port
     
        1.  A logical channel or channel endpoint in a
        communications system.  The {Transmission Control Protocol}
        and {User Datagram Protocol} {transport layer} protocols used
        on {Ethernet} use port numbers to distinguish between
        (demultiplex) different logical channels on the same {network
        interface} on the same computer.
     
        Each {application program} has a unique port number associated
        with it, defined in /etc/services or the {Network Information
        Service} "services" database.  Some {protocols}, e.g. {telnet}
        and {HTTP} (which is actually a special form of telnet) have
        default ports specified as above but can use other ports as
        well.
     
        Some port numbers are defined in {RFC 1700}, divided into
        {well-known ports} and {registered ports}.
     
        2.  To translate or modify
