We are now testing out skolelinux with new edu 6.10 to get them to work
But skolelinux dont have any solution to cluster edu servers.
And ltsp-mosix is too old to use.
To cluster server I'm looking at LVS to load balance the servers.
And then Webmin to cluster the server so package and shell scripts are the
same on all servers.
This mean that you can run update and run scripts on one server and the
other server in the cluster will follow.
And the LVS balance the load of the server and if one server goes down the
other will step in.

(edubuntu)TERMINAL SERVER 2

Switch to thin clients
The clients boot to server ip 192.168.0.3 and the loadbalnce sends the
request to one of the terminal servers.
The next request to ip 192.168.0.3 is sent to the other terminal server.
The terminal server is connected to together with webmin so if you update
terminal server 1, terminal server 2 will also be updated.
So the clients only se one server 192.168.0.3
And if you want to upgrade you can only install one more terminal server to
And then only set the clients to the switch.

Yes, and they do it with LDAP, and NFS home directories.

This would mean that someone who wanted to run more than one Edubuntu
server would need to run 2 distros: 1 Skolelinux as the authentication
server, and then the Edubuntu servers.
Which means running 2 distros. Now, certainly, what's being done for
Edubuntu should allow for an Edubuntu server to authenticate AGAINST an
Skolelinux box, some sites might not want to run more than one distro,
so we need to include the server functionality as well.
