port log

[Warren Togami]

netstat -l
or
netstat -ln

are good to display the exact port and type of protocol (TCP, UDP, RAW) that
are listening.

And yes, nmap scanning yourself works, but it is always better to scan from
another machine.  Ask for a non-priveged shell account on your friend's
machine to nmap scan yourself or something.
