When you want answers to Qs like this, it's a good idea to switch to the 
shell on tty2 and have a look around. There's useful stuff in /proc 
(commandline for the kernel, maybe some stuff for processes), there's 
the environment - the console stuff may be there too.

You _can_ find your server if you're doing ftp/http (nfs too I think), 
and potentially get more info there, perhaps a profile or script that 
makes futher customisations.
