Sorry to take so long to find this but here are places to get a pretty definitave list of ports and their assignments: http://www.isi.edu/in-notes/iana/assignments/port-numbers http://info.internet.isi.edu/in-notes/rfc/files/rfc1700.txt The second files actually accounts for every port below 100 (mentioning which are unassigned). It is some good light reading to do while commuting. (Right and good luck reading it all.) Kirk Wood
