Good luck on _that_. If you want just a fairly comprehensive list of
official TCP/UDP port number assignments, start here:
Link "Protocol Numbers and Assignment Servers" goes to
Link "port numbers" goes to
There are better-organised listings elsewhere (e.g., the one linked from
http://www.networksorcery.com/enp/), but that's the easiest to
find, and has IANA's imprimatur.
Want to know _which_ ports are security-sensitive? Welcome to the study
of security. You'll have fun reading Craig Hunt's _TCP/IP Network
Administration_, Nemeth and Frisch's sysadmin manuals, and a sampling of
the better books on Unix security.
