Thanks.

A google search for "Port n" usually returns good results - since there's a vast amount of information available and I have no idea what you're looking for particularly, I'll let you do the sifting.

You might also try the Internet Port Authority pages at grc.com - try http://grc.com/port_n.htm, replacing the n with the number of the port you're after. I'm not sure how much information they have on the lesser-used ports, though.

hello,
i think you will find that info on this page http://www.chebucto.ns.ca/~rakerman/port-table.html and links in that page
