What user are you trying this as? I think you have to be Administrator or a
user that has priveledges to use raw sockets.

Please note that this mailing list isn't about socket programming in general.
It's about libsocket, a BSD sockets library for DJGPP. You would be better off
asking in the Winsock newsgroup or reading the Winsock Programmer's FAQ.
