= Setting up a LTSP cluster =

This page details the steps to take when setting up an LTSP cluster, similar to the Marbella Cafe setup.

=== Hardware requirements ===
Server+client requirements: http://www.ltsp.org/~sbalneav/LTSPManual.html#requirements-server

Assuming you just want an internet cluster, you will need:

A server (preferably something like a dual core 2Ghz processor, 4GB of
RAM, two network cards and raid - this will be able to handle 12+
client computers I think)<br/>
Desktop PCs (at least a 400Mhz processor, with 256MB RAM, network card
that supports PXE boot. No hdd or cdrom required), with monitors,
keyboards and mice.<br/>
Lots of network cable (this will depend on location, probably best to
have a reel of cat5e and lots of RJ45 connectors).<br/>
A switch (with enough ports for each computer).<br/>
Power strips (again will depend on location).

== Marbella Cafe Setup ==
See the debian HOWTO and Dave's notes.

pxe boot - is assigned an IP address by dnsmasq, then provided with a kernel via tftp<br/>
login screen via ldm (similar to gdm/kdm, but encrypted - this should be disabled for older pcs on a secure network)<br/>
/opt/ltsp/i386/etc/lts.conf - config file containing a list of automatic logins, based on mac address. can also be used to configure screen and other info for each individual client.<br/>
/opt/ltsp/i386 - location of image used after login (accessed via nfs)<br/>
