Default Ports
Ports
utilised by default do depend on what operating system platform you are running.
Having a general idea of what default ports are open on a host is
a good way to "fingerprint" it. Knowing what services run on these ports
also allows you to carry out a great deal of enumeration by banner grabbing
to obtain version and system information. From this information you can
then plan your next step when carrying out the vulnerability
assessment of the entire system.

listing from IANA is available locally, (790kb)
zipped, (226kb) or from their
