These options are mutually exclusive: either you let inetd accept the connections and invoke your program, or your program binds to a port and listens itself for connections on it. The accept call returns the port number of the client in this case.

Inetd has no knowledge of your program if yo uuse the sockets unit, but if you use inetd your program has no knowledge of the remote port.
