This configuration parameter sets the TCP port number the adnisd process uses to create the socket for NIS client communications. For example, the following sets the TCP port to 2556:

nisd.port.tcp: 2556

By default, no port number is specified. If you do not specify the port number, the operating system assigns a random port number.

Use the nisd.port.udp and nisd.net_addr parameters to complete the NIS client socket configuration.
