While the /etc/services file can tell you a good bit about what your computer has to offer, it is not a complete picture. For instance, it doesn't really tell you which port(s) that are used by the "service" <g> of common Trojans and hacking software. It is sometimes interesting to see what ports other computers use for various functions (Black Hat "crackers", games, net "utilitites" like AIM, etc). I have found the following site to be a good portal for info of this kind: http://www.chebucto.ns.ca/~rakerman/trojan-port-table.html#Trojan-Ports . It has some good links to other sites of interest...very good for tracking down strange port probe entries in your firewall's logs. Cheers, -Don Spoon-
