I am running a VNC onto the server, and using a window in there can 
switch users quite happily. But nobody can ssh into the server.

My only thought is that a few days ago I changed the hostname using 
system-network-config but I am pretty certain that I could still ssh in 
after doing that. It just stopped working this morning.

I've even tried rebooting in case there were odd processes hanging 
about, but that's made no difference. At the moment I'm totally stuck!
