A difficult one!

Does anybody know what all of the Windows UDP ports are?

Talking about User Datagram Protocol?

What ports Windows are using with the UDP.. eh.. You have to read all protocol standars that is build on the IP-protocol. Look at http://www.rfc-editor.org to get more info.

Where is that document? I can't find it!!

http://www.protocols.com/protoc.shtml
http://www.cis.ohio-state.edu/htbin/rfc/rfc768.html
http://www.cis.ohio-state.edu/htbin/rfc/rfc762.html

Those describe the UDP protocols and many many others dating back to the '70s. I couldn't find the 32,767 descriptions to the possible UDP ports that you asked for.

I don't think anybody has made a list with all port and it's "common" use.

I did not say that the list was at the site. You have to search and made your own list if you need it that bad.. sorry..

It appears I was a bit over enthusiastic! Does anyone kno wwhat the 10 or so most commonly used ones are? It is for a chat program.

If your making a chat program use your own port number.
Post numbers over 8000 is usually always free.

Thanks!!
