During the development gathering this weekend, Ronny and me worked a bit on adding load balancing support to the LTSP version in Debian Edu 3.0. A version of ldm is now in etch-test with this support. It make it possible to configure LTSP to let the clients pick a ldm server at random from a list, or to write a script to do more advanced selection like based on server load.
To use it, specify several hosts in the LDM_SERVER variable in lts.conf, and make sure the clients ssh know_hosts file include all the servers listed in LDM_SERVER. If you want more advanced load balancing, a script /opt/ltsp/i386/usr/lib/ltsp/get_hosts need to be created to print the server IP (or DNS name if DNS work on the clients). The server is selected by the client when it starts the X server (to make sure the xfs server is the same as the ldm server). In practice this will make the clients select server at boot time. I hope this will make LTSP in 3.0 r1 easier to use with many thin clients. Please test this feature in etch-test and provide feedback. This feedback will decide if the feature is ready for r1 or not.
