Not that I'm inviting anyone to try, but good luck trying to break into area51.slab.conman.org. You won't get very far nor is it a very interesting box. A Compaq 486DX/2 running at 66MHz with 20M of RAM and no harddrive.

It's running a modifed Tom's Rootboot disk [1] distribution with some network monitoring software I wrote. I just thought the name was cute.
