netstat won't display the port, but netstat /a should. (In Windows)

Are you in Windows XP, or do you run a firewall on your machine? It could be preventing the socket from being created or reached.

According to the docs, <HANDLE> shouldn't be used with sockets. sysread should be used instead. I don't think that's the problem, though.

In fact, it ran for on my system after I removed LocalHost => '192.168.1.50', from the server (and you probably shouldn't be using it either) and used '127.0.0.1' for the PeerAddr on the client.
