Here  I gonna introduce to you one of the coolest features of linux- LTSP or Linux Terminal Server project.This is a free package which allows multiple users to use a single system which acts as the server.Programs actually run on the server with teminals known as thin clients or X terminals which merely  handles input and output.Terminals used heremay be low powered  and lack harddisk.This can be very effectively implemented in schools and colleges where buying  expensive systems is not affordable.We can create such a setup easily with C2D  or equivalent system with atleast 1 Gb RAM as server and P2 machines even with 64 Mb as clients.This could actuallly serve all the needs of typical computer lab.You may use a switch or hub to connect multiple clients to the server. 

Setup of  LTSP in UBUNTU

UBUNTU comes with LTSP package by default. So no need to further install it.However we have to do some procedures at the client and server level.

At  Server level

1.Boot your Ubuntu CD.

2.After the CD has booted ,press F4 and select install LTSP server..

3.Install the server just as you install your Ubuntu

4.Setup the IP address to 192.168.1.1  or something when you are asked to do.

At client side

From client computers,enter the BIOS. From the BIOS menu select ‘boot from lan’. This will issue the client computer with a DHCP address and PXE linux file neded for booting will be loaded from the network.If your client boots up to the graphical login and the screen looks similar shown in the figure then you are done!! .Try out this .It can be very useful in case you have some really old junk  systems at your place.
