Years ago - back in about 1998 - there was an incredibly useful tool called the Internet Ports Database running on the domain portsdb.org. I used it about once a week back then, so I was pretty irritated when the site just disappeared over night.

Finally, I've gotten around to producing my own version. You can find the interactive version here: Internet Ports Database. There is also a version for use in scripts. Use curl to send a GET request to http://www.daemonchild.com/pdb/ports.php?port=[port number] and you'll receive a simple format list of ports.
