If you don't care what port you use, you don't need to bind at all. That may be why it's not mentioned - the classic TCP socket server involves bind/listen/accept, and the classic TCP client has just connect; bind/connect is a lot less common. Incidentally, interfaces don't have to correspond 1:1 to network cards. At work, we have a system of four IP addresses for each server, even though it has only one NIC - it's used for traffic management and routing. Binding to a specific address is sometimes important there. Chris Angelico -- http://mail.python.org/mailman/listinfo/python-list
