Installing the Linux Terminal Server (LTSP) on an existing network
This post is two of 3:
1/ Installing the Linux Terminal Server (LTSP) on a stand alone network
2/ Installing the Linux Terminal Server (LTSP) on an existing network
3/ Using the Linux Terminal Server (LTSP) with a Windows Server 2003 DHCP
Although the stand alone installation of a Terminal Server as descibed in post 1 if relatively easy, it will not work on existing networks that already have a DHCP. To use a Terminal Server on your existing network cabling the install is almost as easy:
Start with a clean desktop install of Ubuntu 8.04.
Run all the updates.
Make sure you have a fixed IP address.
Use Synaptic package manager to install LTSP-server (NB NOT the standalone version) and openssh-server (note the terminal server seems to work without openssh-server but will not authenticate).
Open a terminal window and type:
sudo ltsp-build-client
If this finished without errors you should be good for booting clients as long as your DHCP is set up correctly (See Using the Linux Terminal Server (LTSP) with a Windows Server 2003 DHCP).
If you need to change the IP address you will need to run ltsp-update-sshkeys and (maybe?) ltsp-update-image. If you get an error reporting “This workstation isn’t authorized to connect to server” try running these 2 updates.
