PXE Server¶

this image server lives on giljagaur because there is a potential security risk.
Note: foley setup the multiboot, but it is not documented yet. It is in SVN under Machines/PXE

Default config¶

• user root, passwd 100feet
• user test, passwd heistesty!

Installation¶

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

   ssh root@pxe.dev.ru.is

1. Install packages
   

   sudo apt-get install openbsd-inetd tftpd-hpa

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

   subnet 130.208.209.0 netmask 255.255.255.224 {
       <other config here>
       filename "pxelinux.0";
       next-server pxe;
   }
   

3. 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)
   

   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 {} \;
   

4. Copy the data into the tftp directory
   

   sudo cp -r ubuntu-netboot/* /var/lib/tftpboot/

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

   sudo apt-get install tftp-hpa
   cd /tmp
   tftp pxe -v -m binary -c get pxelinux.0
   

Kickstart¶

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

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

   sudo apt-get install apache2

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

   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

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

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

4. 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
   

   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\
   er/i386/initrd.gz --
