On this page, you find notes about transforming a vanilla (=raw) tjener (mainserver) into a server for installing workstations over the network.

UPDATE : use SysadminHowTo/NetworkInstall

This is "materialising" an idea, which started during a weekend at the German Skolelinux testcenter. When it works, the contents of this page should move to a howto.

vanilla tjener mainserver

We start with assuming an plain unmodified tjener.

probably already described better a at better place 'FIXME'


The workstations to be, do a network boot. ( http://www.google.de/search?q=network+boot )

Tuning of the Tjener

Install a tftpd server by

 apt-get install tftpd-hpa

You may have to use a newer tftpserver than the one that comes with woody. (See ArbeitsTreffen0507/NewerTftpServer for details)

Create a directory for the boot files

Create a symbolic link from pxelinux.0 from the syslinux package in that directory

 ln -s /usr/lib/syslinux/pxelinux.0 /tftpboot/wkst/

Mount the debian-edu CD-ROM

 mount /cdrom

Copy various boot files from the CDROM into the workstation network boot dir.

 cp /cdrom/install/vmlinuz /cdrom/install/initrd.gz /tftpboot/wkst/

Create under wkst/ a pxelinux.cfg directory

 mkdir /tftpboot/wkst/pxelinux.cfg

Create a file named default in that directory with this content

Unmount the cdrom

 umount /cdrom


The install stops after the language selections because it can't find the next information ( it thinks it is on the CD )

Way to go:

Create an initrd.gz that is aware of being a network install.

Debian-Installer, http://www.nl.debian.org/devel/debian-installer/, supports it.
