What is LTSP? /1
● Linux Terminal Server Project (LTSP) is an add-on package 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” handling input and output.
● These thin clients are also known as X Terminals. Generally, they are low-powered and lack a hard disk.
What is LTSP? /2
● This technology is becoming popular in schools as it allows pupils access to computers without purchasing expensive desktop machines.
● Some examples of distributions using LTSP are K12LTSP, Skolelinux and Edubuntu.
● Old computers can easily be turned into thin clients.
A sample infrastructure
Clients:● Thin client● Old PCs
Thin Client Terminals
How to work /1
Services accessed by client:– DHCP server– TFTP– NFS– XDMCP
How to work /2
Installing LTSP
● Install the ltsp-utils package
– RPM for Redhat,Suse,Mandrake, etc...– .deb for debian and friends– .tgz tarballs for everybody else
● Run ltspadmin
– This will download the packages that make up the root filesystem for the thin clients.
Costs
● LTSP and Thin client allow cost saving● Example: Imagine a school where 50
client need to be updated:– Case 1: buy new 30 clients: ~700x30 € =
21000€– Case 2: buy only a new server and reuse
old workstations as thin clients: ~5000€
