Which ports are dangerous when using TCP/IP? Simple, the one you forgot to
shutoff or didn't know about.
Its not as simple as the port number but rather what daemons or services
are listening on them.
If you are concerned about your own site's security a good rule of thumb is
to make sure you are
not running any services that you don't need. i.e. A default inetd or
NetBIOS open to the Internet.
Historicly some services(running on standard ports) have had problems which
pose dangers to the security of a site,
you might be interested in taking a look at
http://sunsite.auc.dk/RFC/rfc/rfc2196.html which is the rfc covering site
security.
