the ports above 1024 are allowed to be bound by non-root users. In your
/etc/services file is a list of what service uses what port. Rick has a
nice list on his website www.pointman.org of what services use what
port. You can use netstat -an to see what is actually bound to what.
Anything in a LISTEN state is excepting connections.
