Doing a little "work" this evening, I came across the following:

Port State Service
21/tcp open ftp
22/tcp open ssh
23/tcp open telnet
53/tcp open domain
80/tcp open http
135/tcp filtered loc-srv
139/tcp filtered netbios-ssn
443/tcp open https
445/tcp filtered microsoft-ds
593/tcp filtered http-rpc-epmap
3306/tcp open mysql
4444/tcp filtered krb524
5555/tcp filtered freeciv
6346/tcp filtered gnutella
6666/tcp filtered irc-serv
6699/tcp filtered napster
8888/tcp filtered sun-answerbook

This is from an educational institution, and a quick telnet to port 23 does in fact give you a login prompt.

No big deal there, however the question I have is this:

Port 6699 is designted as "napster." I haven't seen this one before. Is this because:

1. It is a napster server?

2. They know students will use napster, so designte a port for it?

3. Have no clue, and someone has set up napster to run through the server while the admin(s) re oblivious?

Any guesses? Has anyone seen this before?
