Thanks for the input, David.
Still getting my head around *NX. Can the client work from the thin-
clients without loading a windowing system?
In the meantime, I found this article http://ubuntuforums.org/archive/index.php/t-368869.html
Looking around the configuration files I don't see any compression
enabled in /var/lib/tftpboot/ltsp/i386/lts.conf so I've added:
## SSH compression between LTSP client and server
NETWORK_COMPRESSION = True
remotely, but haven't been onsite to test it yet.
/var/lib/tftpboot/ltsp/i386/config-2.6.38-8-generic has several
compression parameters, but nothing explicitly about SSH from what I
Will post an update when I've had a chance to test.
