Hi, > About the best solution I've seen is to distribute the XDMCP sessions > between the servers. Yeah, that's right. Dispatching sessions on servers is realy easy to do.
Install one server as a the "master", that will run nfsd home and client root, nis (or slapd) tftpd, dhcpd and xdmcp. On other "secondary" server, configure them to be client of the master server (ldap authentication, mount nfs homes, etc.). Secondary servers are like standard networked workstations that will be used to serve desktop applications to users. If you need high avaibility for the master server, than double it with heartbeat. I'm not aware of practical solution for desktop session migration, in the case of a secondary server goes down. Sessions are lost. For load-balancing sessions, the next release of ubuntu gutsy in few days will make this easier. And, the edubuntu handbook covers this aspect. You can also take a look to ltsp-loadbalancer : https://svn.revolutionlinux.com/MILLE/XTERM/branches/ltsp-cluster/ltsp-loadbalancer/ One thing that will not work at this moment is student-control-panel, because it's targeted for a single host system.
