Ubuntu 11.10 LTSP

For funsies I wanted to find out how to set up an Ubuntu 11.10 LTSP. The instructions below are what I put together after searching websites, emailing for answers, reading forum posts and trial and error. This works for me on a fresh install of Ubuntu and I hope it works for you if you give it a try.

Please note the following items:

I wanted the thin clients to have Unity 2D, so that is why the lts.conf/LDM instructions are in there. My second network card for the internal LTSP network is eth1 – yours might be different, so change the related entries in /etc/default/isc-dhcp-server and /etc/network/interfaces if needed.

I used 192.168.22.X for my internal LTSP network, but you can have something else entirely like 10.10.22.X for example. If you decide to go with something different please remember to update the /etc/network/interfaces address and /etc/ltsp/dhcpd.conf accordingly.

INSTALL LTSP IN UBUNTU

Open terminal window
- sudo bash & enter password
- apt-get update && apt-get upgrade -y
- apt-get install ltsp-server-standalone openssh-server
- gedit /etc/default/isc-dhcp-server
      add eth1 as follows:
           INTERFACES=”eth1″
      save and exit
- gedit /etc/network/interfaces
      add the following under the existing auto lo entry
           auto eth1
           iface eth1 inet static
                address 192.168.22.1
                netmask 255.255.255.0
      save and exit
- ifup eth1
- gedit /etc/ltsp/dhcpd.conf
      change all 192.168.0.X to 192.168.22.X
           I use gedit’s replace function: 168.0 > 168.22
      save and exit
- /etc/init.d/isc-dhcp-server restart
- ltsp-update-sshkeys
- ltsp-build-client –-arch i386
- /etc/init.d/nbd-server restart
- /etc/init.d/isc-dhcp-server status
- gedit /var/lib/tftpboot/ltsp/i386/lts.conf
      add the following:
           [default]
           LDM_DIRECTX=True
           LDM_SESSION=”gnome-session –session=ubuntu-2d”
      save and exit
- Reboot system for good measure

Click user icon/name top right of ubuntu desktop
- click user accounts
- click unlock (top right of window)
- enter password and authenticate
- click + sign (bottom left) to add new user account
- account type = standard
- full name = tc1 (for thinclient1 – use whatever you want)
- click create
- click account disabled to right of password
- add password and retype to confirm
- click lock (top right of window)

Hook up thin clients, select network boot, and login

If you can’t login because client says ‘response from server, restarting…’ try the following:

Open terminal window
- sudo bash & enter password
- ltsp-update-sshkeys
- sudo ltsp-update-image
- /etc/init.d/nbd-server restart
- reboot clients and try to log in
