I am fond of snort at http://snort.sourcefire.com/ports.html, but a search for icq turned up nothing.  Other interesting site are:

thanks geoffryn i managed to find a superb little text-based app called FPort.
run it and you see every open port that is in use and the app using it.
obviously that's on the current machine
for the moment this is for use on a server i am using with ZoneAlarm so it's ideal.
thanks for the links.
