The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic.They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. Running the NSCA daemon under inetd and making use of TCP wrappers allows you to perform some host-based authentication of clients.
