Updated: Ubuntu LTSP Server

In 2007 I posted a guide to installing an Ubuntu LTSP Server. Since then, Ltsp has become a lot easier to install, setup and use.

Installation basically consists of:

• sudo apt-get install ltsp-server-standalone openssh-server

and

• sudo ltsp-build-client (or ¨sudo ltsp-build-client --arch i386¨ if your on a 64-bit system with 32-bit machines)

You will want edit the /etc/ltsp/dhcpd.conf file to set the server’s IP values:

• gksudo gedit /etc/ltsp/dhcpd.conf

Make sure the lines for domain-name-servers and routers match your network setup if you want to give the thin clients Internet access

Then restart the dhcp server with:

• sudo /etc/init.d/dhcp3-server restart

And do the following to update the SSH server:

• sudo ltsp-update-sshkeys

After that, you will be able to boot your first thin client. On older clients without a ¨Boot from network¨ option in the BIOS, you can use Etherboot or ROM-o-matic. Too write the image to floppy do

• cat filename.extension > /dev/fd0

This  basically all there is on the Ubuntu LTSP wiki page, although there are many more options as far as customization goes.
