I think the first thing is "netstat -a" which will tell you which ports are
open 
If you see some you don't expect, trace it with tcpdump
if you don't see any, they may have installed a hacked version of some
common daemon
they may also have changed inetd.conf and redirected some normal app to a
root shell

if you find something interesting with netstat, try netstat -p
