I bought a new Airport Extreme the other day. Since it does disk/printer/network sharing I figured it would be a little bit more interesting than my last Airport.

$ sudo nmap -A -F airport

Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2007-02-21 15:00 PST
Interesting ports on airport:

Interesting indeed.
