Step 3: set up the listen port monitor

The listener is a port monitor under the control of the Service Access Controller (SAC), a daemon process that provides a consistent interface to all services, whether the user's connection to the system is local or across a network. (Because the purpose of the SAC is not limited to managing network access, it is not documented in this topic. For more information about the SAC and setting up the listener, see ``The Service Access Facility'' and ``Administering the listen port monitor''.) To set up the listener, do the following:

1. Add a listen port monitor to the SAC's administrative file, using sacadm(1M).

2. Set up the port monitor's administrative file, using pmadm(1M). Setting up the file involves:

   • adding one or more services to the listener's administrative file

   • enabling the service on a port that the listener is monitoring

   • associating an authentication scheme with a service
