Can someone refer me to a document listing all of the TCP and UDP ports?
TIA.
Lou
Wow, that's easy. Try:
for(i = 0; i < 65536; i++)
{
cout << "TCP port " << i << endl;
cout << "UDP port " << i << endl;
}
Sorry, that was cheap. Couldn't resist.
Lou, there are several documents you might want to get your hands on. The
canonical choice is this book:
Building Internet Firewalls
By D. Brent Chapman & Elizabeth D. Zwicky
1st Edition September 1995
1-56592-124-0, Order Number: 1240
544 pages, $32.95
If you don't have it, get it. It contains a rather detailed list of ports and
what services they're usually assigned to. Of course, this book is rather
UNIX-centric. If you're in an environment with Wintel boxes, there is a lot
more to watch out for. We've all seen how many skeletons are in Microsoft's
closet over the past few months. A listing of the ports assignments including
those specific to MS can be found in the resource kits for NT WS 4.0 and
Server 4.0. WS Resource Kit is somewhere 'round $70, not sure about the server
kit. Note that this is just a list with only one or two lines of
explanation. You'll have to hunt and peck through vendor documentation (MS,
Novell, whatnot) to get a clearer view. That is, IF the stuff is properly
documented at all. Then again, someone might come up with a more detailed
reference to Wintel-specific port assignments.
