This can also be found on any *nix box by doing a 'cat /etc/services'

Thanks for the link. I will definitely be bookmarking that for future reference.

From what I can see the owner of that site tries to update the list periodically. It may prove helpful in the future if you have weird activity on some port to visit this site and see what it might be.

I like the fact that he not only enumerates the ports and what services run on them, but he talks about the common applications that may use it and the potential problems associated with it. It is much more informative than simply associating a service name with a port number.

Great Information!

That's a great help thanks.

Two other good helpers when you want to find information about ports are: Snort DB, Ports DB.

then there is always the source to go to, and one that is constantly updated as ports change:


http://www.iana.org/assignments/port-numbers


I know it's a bit different than the one that was originally posted, but I use the IANA reference for just about all of my port look ups now.
