I'd suggest to find the Richard W. Stevens book "Unix Network Programing".
You'll learn a lot about networking from that book. It's based on C, but
you'll see that the concepts can be easily used with Python too.

Find that book, and don't forget the stdlib docs:
http://docs.python.org/lib/module-socket.html
http://docs.python.org/lib/module-select.html
