   Port numbers available for use?
  Hey guys.I'm totally new to network programming.  But I'm trying!  Anyhoo, I'm wondering what port ranges are available for use in indie games...  I know that chat programs use certain ports (Yahoo, MSN Messenger, etc), and so do popular online games (Quake3, HalfLife2, etc).  The Paper-Scissors-Rock socket programming demo uses port 5555 (which Norton AntiVirus picks up as a trojan - go figure).  What ports should I use for my games that won't infringe upon any of the standards?Thanks in advance for the info!   
WELL KNOWN PORT NUMBERS;  Cool, thanks for the info LessBread!Just to make sure I understand correctly, I can pretty much use any port number from 49152 through 65535?   ;  I'm not an expert but you might be better off using an unassigned port numbers in the range 1024-49151.   ;  Some time ago, I had a problem where only one test user couldn't connect to my server and it turns out that his ISP was blocking him from sending anything to that particular part.  Make sure you keep this possibility in mind as I spent nearly a week looking for the cause of this problem.
