Specify the SO_REUSEADDR socket option after you create the socket.  By
default, the old socket stays around in the TIME-WAIT state for a while so
that the system can reject retransmissions from old connections.

You use shutdown(2) when you want to close only one direction of
communication.  This is pretty rare.
