32 listens on a network for inbound calls to local services.

58 a new namespace is created,
67 option limits the number of processes that
69 spawns to service the connections. If the
73 will log the event and delay servicing until the number
74 of connection processes drops below the limit again. A
76 smaller or equal zero means no limit (default).
79 suppresses affirmative log information.
82 suppresses the periodic scan of the service directories for changes.
84 Service names are made by concatenating the name of
85 the network with the name of the service or port.
87 an inbound call on the TCP network for port 565 executes service
