How To Install LTSP in Ubuntu 11.04 Natty Narwhal

Linux Terminal Server Project (LTSP) is a free and open source software for Linux that allows many people to simultaneously use the same computer. Applications run on the server with a terminal known as a thin client (also known as an X terminal) handling input and output. Generally, terminals are low-powered, lack a hard disk and are quieter than desktop computers because they do not have any moving parts.
In case of the newer MueKow (LTSP 5) setup, the client first builds an SSH tunnel to the LTSP server's X environment, through which it will start the LDM login manager (on the LTSP server). From this point forward, all programs are started on the LTSP server, but displayed and operated from the client.

See How to install LTSP in Ubuntu with few simple steps.
First You have to set a Static IP address in Your Machine to 192.168.0.1
( See How to setup static IP)
Now
Open a terminal in your existing Ubuntu Machine ad type the following Commands

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

$ sudo ltsp-build-client
$ sudo /etc/init.d/networking restart
$ sudo /etc/init.d/dhcp3-server restart


Now Your LTSP Server is ready. Set PXE boot in client system ( This means you have to select Network card as your Boot Device).

If you change your IP Address You have to do the following
* Configure DHCP Server (/etc/ltsp/dhcpd.conf)
* Run command "sudo ltsp-update-sshkeys"
