h2. Installation

# Login to pxe.dev.ru.is (password 100feet for now)

<pre>ssh root@pxe.dev.ru.is</pre>

# Install packages

<pre>sudo apt-get install openbsd-inetd tftpd-hpa</pre>

# setup [[DHCP Server]] to give appropriate image (edit /etc/dhcp3/dhcpd.conf on dhcp.dev.ru.is)

<pre>subnet 130.208.209.0 netmask 255.255.255.224 {

    <other config here>

    filename "pxelinux.0";

    next-server pxe;

}

</pre>

# Download the latest version of the alternate install netboot stuff (@precise@ is the name of ubuntu release 12.04, change it for installing an different version)

<pre>

wget -r -nH -P ubuntu-netboot/ --cut-dirs=8 -np http://ubuntu.lhi.is/ubuntu/dists/precise/main/installer-i386/current/images/netboot/

# remove some unnecessary files

find ubuntu-netboot/ -name 'index.html*' -exec rm {} \;

</pre>

# Copy the data into the tftp directory

<pre>sudo cp -r ubuntu-netboot/* /var/lib/tftpboot/</pre>

# Test that tfpd is working.  You should see a pxelinux.0 file when this runs correctly and some information about the transfer

<pre>sudo apt-get install tftp-hpa

cd /tmp

tftp pxe -v -m binary -c get pxelinux.0

</pre>

h3. Kickstart

Kickstart allows you to answer most of the questions that would occur during install beforehand and save this information as file.

# Install apache (or some other webserver) to make the kickstart file available

<pre>sudo apt-get install apache2</pre>

# Find a debian machine with Xwindows and use system-config-kickstart to create @ks.cfg@

<pre>sudo apt-get install system-config-kickstart

system-config-kickstart

scp ks.cfg root@pxe.dev.ru.is:/var/www  # copy to http server on pxe</pre>

# OR Grab the @ks.cfg@ from SVN in Machines/PXE.  You may need to be in www-data group on the machine

<pre>cp /afs/dev.ru.is/project/devnet/workspace/Machines/PXE/ks.cfg /var/www</pre>

# edit the pxe boot menu @/var/lib/tftpboot/ubuntu-installer/i386/boot-screens/txt.cfg@ (@text.cfg@ in older versions) and add the following lines to add an entry which uses the kickstart file

<pre>label install-ks

        menu label ^Install using Kickstart

        menu default

        kernel ubuntu-installer/i386/linux

        append ks=http://pxe.dev.ru.is/ks.cfg vga=normal initrd=ubuntu-install\
