    From the man page:

	s_port     The port number at which the service resides.
		   Port numbers are returned in network byte order.

    which is the same byte order which it should be shoved into sockaddr_in.

    In order to get it in the right byte order to print out in human readable form
    you need to use the ntohs() routine.
