Installation on Slackware 14

2019-07-21T12:59:49Z

Roberto.puzzanghera: /* Contact */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.2 to 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget https://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.2.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 123 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 460M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.2".

wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.2.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.1, 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==

Installation on Slackware 14

2016-07-09T12:26:25Z

Roberto.puzzanghera: /* Patch applayed */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.2 to 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.2.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 123 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 460M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.2".

<pre>
#!/bin/bash
#
# v. 2016.06.08
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.2" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Installation on Slackware 14

2016-07-05T12:29:50Z

Roberto.puzzanghera:

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.2 to 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.2.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 123 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 460M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.2".

<pre>
#!/bin/bash
#
# v. 2016.06.08
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.2" # Slackware version

# put here your pkg list

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE

PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.2.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.1, 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2016-07-05T12:25:42Z

Roberto.puzzanghera: /* Make the guest */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.2.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 123 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 460M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.2".

<pre>
#!/bin/bash
#
# v. 2016.06.08
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.2" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2016-07-05T12:24:43Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.2.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 123 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 460M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.2".

<pre>
#!/bin/bash
#
# v. 2016.06.08
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.2" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2016-07-05T12:23:23Z

Roberto.puzzanghera: /* Download */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.2.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# $PWD should work, otherwise put /path/to/slack_vserver

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2014-08-05T18:31:47Z

Roberto.puzzanghera: /* Patch applayed */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# put here your pkg list

# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>
Patch for Slackware 14.1 guest on a Linux-Vserver host

Installation on Slackware 14

2014-01-05T18:28:40Z

Roberto.puzzanghera: /* Make the guest */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2014-01-05T18:24:59Z

Roberto.puzzanghera: /* Contact */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>
Patch for Slackware 14.1 guest on a Linux-Vserver host

Installation on Slackware 14

2014-01-05T18:23:43Z

Roberto.puzzanghera: /* Apply the patch */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 14.0, 13.37 and 13.1, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2014-01-05T18:23:10Z

Roberto.puzzanghera: /* Apply the patch */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.1.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2014-01-05T18:22:15Z

Roberto.puzzanghera:

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository

# put here your pkg list

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-12-29T13:34:02Z

Roberto.puzzanghera: /* Patch applayed */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1** (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-12-29T13:33:00Z

Roberto.puzzanghera: /* Make the guest */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1** (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# put here your pkg list

# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-12-29T13:31:26Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1** (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2013.12.29
# Now the script parses comments in the package list (thanks to Mark Colclough)

VERSION="14.1" # Slackware version

# put here your pkg list

# $PWD should work, otherwise put /path/to/slack_vserver

# the directory where you want to download the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
[ "$LINE" ] || continue
[ "${LINE#\#}" = "$LINE" ] || continue
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
[ "${PKG#\#}" = "${PKG}" ] || continue
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

</pre>

Note that ''/etc/resolv.conf /etc/localtime /etc/profile'' are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>
Patch for Slackware 14.1 guest on a Linux-Vserver host

Installation on Slackware 14

2013-11-10T14:04:03Z

Roberto.puzzanghera:

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.1, 14.0, 13.37 and 13.1** (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Note that ''/etc/resolv.conf /etc/localtime /etc/profile'' are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-11-08T22:17:11Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.1".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Note that ''/etc/resolv.conf /etc/localtime /etc/profile'' are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.

./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-11-08T22:16:49Z

Roberto.puzzanghera: /* Download */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* linux-vserver_slackware-14.1.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-11-08T21:51:17Z

Roberto.puzzanghera: /* Patch applayed */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.1" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# $PWD should work, otherwise put /path/to/slack_vserver

# the directory where you downloaded the slackware packages

# create the folder where the pkg will be downloaded

fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2013-11-08T21:49:37Z

Roberto.puzzanghera: /* Make the guest */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Note that ''/etc/resolv.conf /etc/localtime /etc/profile'' are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>
Patch for Slackware 14.0 guest on a Linux-Vserver host

Installation on Slackware 14

2013-11-08T21:48:59Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.1" # Slackware version

# put here your pkg list

# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# create the folder where the pkg will be downloaded

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-10-19T20:29:14Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the ''slackware{$ARCH}-{$VERSION}_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh script''.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages or empty otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>

</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>
Patch for Slackware 14.0 guest on a Linux-Vserver host

Installation on Slackware 14

2012-10-19T20:26:46Z

Roberto.puzzanghera: /* Make the guest */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages and blank otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

Note that ''/etc/resolv.conf /etc/localtime /etc/profile'' are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.

./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-10-19T20:26:22Z

Roberto.puzzanghera: /* Make the guest */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages and blank otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>

exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script ''make_slack_vserver.sh'':

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-10-19T20:25:13Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script ''download_slack_pkg.sh''. It can create a folder like ''slackware{$ARCH}-{$VERSION}_pkg'' for you, where ''$ARCH'' has to be "64" if you want to download 64b packages and blank otherwise, while ''$VERSION'' is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#

VERSION="14.0" # Slackware version

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do

PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package ''PKG_LIST'', enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the ''/slackware'' folder with the updates belonging to the ''/patches'' dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

Note that /etc/resolv.conf /etc/localtime /etc/profile are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-10-01T17:05:00Z

Roberto.puzzanghera: /* Download */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware.

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version

exit 1
fi

rm index.html*
</pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-10-01T17:03:17Z

Roberto.puzzanghera:

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working.

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware. Comments would be welcome about this :-).

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-09-29T14:39:48Z

Roberto.puzzanghera: /* Contact */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working. You can find here a quick and easy howto concerning Linux-Vserver installation and configuration (patching the kernel + utils-vserver installation).

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware. Comments would be welcome about this :-).

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-09-29T14:39:21Z

Roberto.puzzanghera: /* Patch applayed */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working. You can find here a quick and easy howto concerning Linux-Vserver installation and configuration (patching the kernel + utils-vserver installation).

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware. Comments would be welcome about this :-).

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-09-29T14:35:39Z

Roberto.puzzanghera: /* Download */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working. You can find here a quick and easy howto concerning Linux-Vserver installation and configuration (patching the kernel + utils-vserver installation).

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware. Comments would be welcome about this :-).

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 14

2012-09-29T14:34:41Z

Roberto.puzzanghera: /* Download the packages */

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working. You can find here a quick and easy howto concerning Linux-Vserver installation and configuration (patching the kernel + utils-vserver installation).

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware. Comments would be welcome about this :-).

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

Note that /etc/resolv.conf /etc/localtime /etc/profile are copied form the host.

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.
<pre>
./make_slack_vserver.sh
</pre>

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>
Patch for Slackware 14.0 guest on a Linux-Vserver host

Installation on Slackware 14

2012-09-29T14:33:12Z

Roberto.puzzanghera: Created page with 'The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux…'

The purpose of this note is to setup a guest based on Slackware. What follows was tested on Slackware 14.0, 13.37 and 13.1 (both 32b and 64b). I will assume that you have a Linux-Vserver box working. You can find here a quick and easy howto concerning Linux-Vserver installation and configuration (patching the kernel + utils-vserver installation).

== Download ==
<pre>
wget http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz
tar xzf slack_vserver.tar.gz
cd slack_vserver
ls
</pre>

You have downloaded the following files:

* PKG_LIST is the package list to be installed in the guest
* download_slack_pkg.sh is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware[64]-version_pkg sub-folder.
* make_slack_vserver.sh is the shell script that you have to adjust. It installs the guest.
* rc is the startup script for the virtual server. It will be automatically copied in /etc/rc.d* /init.d/rc
* slackware-14.0.patch is the patch which modify rc.0, rc.6 rc.M, rc.S, rc.inet2 and rc.syslog. It must be applyed after the creation of the vserver process. In the patch I switched off all the mounts and executable that are related to the hardware. Comments would be welcome about this :-).

== Download the packages ==

First of all select a minimal set of packages to be installed on the virtual server. This list of 110 packages is based on the Minimal System reported at http://slackwiki.org/Minimal_System without all hardware, kernel and multimedia related packages. The install leads to a guest of about 448M of size. This set fits with the installation of a complete virtual web server including apache, apache-tomcat, php, mysql, postgresql, qmail and related, ftp, named.

I assume that the packages to be installed are stored in the slackware{$ARCH}-{$VERSION}_pkg folder. If not, adjust its location editing the make_slack_vserver.sh script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh. It can create a folder like slackware{$ARCH}-{$VERSION}_pkg for you, where $ARCH has to be "64" if you want to download 64b packages and null otherwise, while $VERSION is the Slackware version, so it's something like "14.0".

<pre>
#!/bin/bash
#
# v. 2012.09.29

VERSION="14.0" # Slackware version
ARCH="64" # you can put 64 for 64b cpu just to separate 64/32 download folders

# Put here your favourite Slackware repository
SRC="ftp://ftp.slackware.no/slackware/slackware${ARCH}-${VERSION}/"

# put here your pkg list
LIST="${PWD}/PKG_LIST"

# the directory where you unpacked slack_vserver.tar.gz
# $PWD should work, otherwise put /path/to/slack_vserver
SETUP=$PWD

# the directory where you downloaded the slackware packages
PACKAGES="${SETUP}/slackware${ARCH}-${VERSION}_pkg"

# create the folder where the pkg will be downloaded
if [ ! -d "$PACKAGES" ]; then
mkdir -p $PACKAGES
fi

# create the "patches" sub-folder
if [ ! -d "${PACKAGES}/patches" ]; then
mkdir -p "${PACKAGES}/patches"
fi

# download
cd $PACKAGES

if [ -f $LIST ]; then
while read LINE
do
wget "${SRC}slackware${ARCH}/${LINE}*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*

# download packages from the patches folder
cd ${PACKAGES}/patches

if [ -f ${LIST} ]; then
while read LINE
do
IFS='/' read -ra PKG <<< "$LINE"
PKG_LEN=${#PKG[@]}
if [ $PKG_LEN == 2 ]; then
wget "${SRC}patches/packages/${PKG[1]}*.t?z"
fi
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package PKG_LIST, enter your favorite ftp server and run from the command line

<pre>
./download_slack_pkg.sh
</pre>

NB: this script tries also to overwrite the packages downloaded from the /slackware folder with the updates belonging to the /patches dir.

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the rc.* startup scripts removing all the hardware related daemons, and finally replace the /dev dir.

This is done adjusting and running the script make_slack_vserver.sh:

Edit the script inserting at least the NAME, the IP and the CONTEXT. The packages' location should be ok if you downloaded them using my script.

== Apply the patch ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-14.0.patch
</pre>

Inside the tarball you can find the old patch for Slackware 13.1 and 13.37, if you like.

== Post installation tasks ==

Put this inside your rc.local:
<pre>
/usr/local/etc/rc.d/init.d/vprocunhide start
</pre>

== Start the new server ==
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

== Patch applayed ==
<pre>

Installation on Slackware 13

2011-07-28T20:59:12Z

Roberto.puzzanghera: /* Download the slack packages */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-04-28T22:41:03Z

Roberto.puzzanghera: /* Apply the patch and start the guest */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-04-28T22:39:26Z

Roberto.puzzanghera: /* Download the slack packages */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-04-28T22:37:06Z

Roberto.puzzanghera: /* Download the slack packages */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [[PKG_LIST Slackware_package_list]], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

Installation on Slackware 13

2011-04-28T22:35:54Z

Roberto.puzzanghera: /* Download the slack packages */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [[Slackware_package_list PKG_LIST]], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

Installation on Slackware 13

2011-04-28T22:35:29Z

Roberto.puzzanghera: /* Download the slack packages */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [#Slackware_package_list PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

Installation on Slackware 13

2011-04-28T22:33:42Z

Roberto.puzzanghera: /* Download the slack packages */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

Installation on Slackware 13

2011-04-28T22:31:41Z

Roberto.puzzanghera: /* Download the patch and the installer script */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M'' and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
</pre>

Installation on Slackware 13

2011-04-28T22:31:06Z

Roberto.puzzanghera: /* Download the patch and the installer script */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.37.patch] is the patch which modify ''rc.6'' ''rc.M and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

Installation on Slackware 13

2011-04-28T22:29:06Z

Roberto.puzzanghera: /* Slackware package list */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.1.patch] is the patch which modify ''rc.6'' ''rc.M and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.1.patch] is the patch which modify ''rc.6'' ''rc.M and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter

Installation on Slackware 13

2011-04-28T22:26:58Z

Roberto.puzzanghera: /* Hints */

What follows was tested on a Slackware 13.37 and 13.1 guest. I assume you have a Linux-Vserver host working.

== Download the patch and the installer script ==
* [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/slack_vserver.tar.gz slack_vserver.tar.gz]

<pre>
tar xzf slack_vserver.tar.gz
cd slack_vserver

ls
</pre>

* [http://www.linux-vserver.org/Installation_on_Slackware_13#Slackware_package_list PKG_LIST] is the package list to be installed in the guest
* slackware_pkg/ is the folder were the packages (txz) to be installed are stored.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Download_the_slack_packages download_slack.sh] is a script that you can use to download all the PKG_LIST. If you use this scriptlet all the package will be stored in the slackware_pkg sub-folder.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Make_the_guest make_slack_vserver.sh] is the shell script that you have to adjust. It installs the guest.
* [http://www.linux-vserver.org/Installation_on_Slackware_13#Patch_used slackware-13.1.patch] is the patch which modify ''rc.6'' ''rc.M and ''rc.inet2''. It must be applyed after the creation of the guest. In the patch I switched off all the mounts and executable that are related to the hardware.
* ''rc'' is the startup script for the virtual server. It will be automatically copied in ''/etc/rc.d/init.d/rc''
<pre>
# more rc

#!/bin/bash

if [ "$1" == "3" ]; then
/etc/rc.d/rc.M
elif [ "$1" == "6" ]; then
/etc/rc.d/rc.6
else
echo "Invalid level."
exit 1
fi
</pre>

== Download the slack packages ==

First of all select a minimal set of packages to be installed on the virtual server. [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST This list] of '''109 packages''' is based on the Minimal System reported at [http://slackwiki.org/Minimal_System http://slackwiki.org/Minimal_System] without all hardware, kernel and multimedia related packages. The install leads to '''a guest of about 448M of size'''.

I assume that the packages to be installed are stored in the ''slackware_pkg'' folder. If not, adjust its location editing the ''make_slack_vserver.sh'' script.

You can download my minimal set of packages running the shell script download_slack_pkg.sh
<pre>
#!/bin/bash
#
# v. 2011.01.07
# Put here your favourite Slackware repository

SRC="ftp://ftp.slackware.no/slackware/slackware-13.1/slackware/" # 32-bit
#SRC="ftp://ftp.slackware.no/slackware/slackware64-13.1/slackware64/" # 64-bit

LIST="../PKG_LIST"

cd slackware_pkg

if [ -f $LIST ]; then
while read line
do
wget "$SRC$line*.t?z"
done < $LIST
else
echo "Can't find $LIST file."
exit 1
fi

rm index.html*
</pre>

Adjust the package [http://notes.sagredo.eu/sites/notes.sagredo.eu/files/linux-vserver/PKG_LIST PKG_LIST], enter your favorite ftp server and run from the command line
<pre>
./download_slack_pkg.sh
</pre>

== Make the guest ==

Now let's create the guest and install the packages. As you know you must choose at least a "name", a "context" and an ip. In addition you have to modify most of the ''rc.*'' startup scripts removing all the hardware related daemons, and finally replace the ''/dev'' dir.

This is done running the script ''make_slack_vserver.sh'':

== Apply the patch and start the guest ==

The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:
<pre>
cd /vservers/vserver_name/etc/rc.d
The script itsself can install the patch for you. Anyway this is how to apply the patch by yourself:patch -p1 < /path/to/slack_vserver/slackware-13.37.patch
</pre>

Now you can start the newly created virtual server:
<pre>
vserver <vserver_name> start
vserver <vserver_name> enter
