 You shouldn't bind your client on a port where your server is listening

I'm following what is written in "Peer-to-Peer Communication Across
Network
Address Translators" in order to implement TCP hole punching, and they
suggested to do so..


Are you talking about section 4.2?  If so, try creating the client before
you create the server.  This is a somewhat arbitrary limitation imposed by
your platform's implementation of the BSD socket API.


Thanks for the suggestion, I'll try this and let you know.


Well, apparently at least on my Linux box, I still have the same address
already bound error even if I first do connect() and then listen() using the
Twisted reactor APIs  (connectTcp(), listenTcp() ).

Any clue?

You might have to create and connect the socket before giving it to Twisted
then.
