30 listens on a network for inbound calls to local services.
32 is the network protocol on which to listen, by default
34 The services available are executable, non-empty files in
44 looks for executable files in
52 are executed as the user who started
56 a new namespace is created,
65 option limits the number of processes that
67 spawns to service the connections. If the
71 will log the event and delay servicing until the number
72 of connection processes drops below the limit again. A
74 smaller or equal zero means no limit (default).
77 suppresses affirmative log information.
80 suppresses the periodic scan of the service directories for changes.
82 Service names are made by concatenating the name of
83 the network with the name of the service or port.
85 an inbound call on the TCP network for port 565 executes service
88 At least the following services are available in

105 serve a piece of the name space using the Plan 9 file system protocol,
106 with authentication at the start,
107 optional SSL encryption,
108 and no multiplexing of users
119 but serves the root of the tree,
120 forgoing the negotiation for which subtree to serve.
134 command for compatibility with old clients.
137 echo any bytes received (bit mirror)
140 consume any bytes received (bit bucket)
151 `secure shell' encrypted terminal connection or file transfer.
175 CIFS/SMB file sharing.
186 report the address of the incoming call.
189 Secure IMAP4rev1 port.

222 for each incoming connection;
223 the network directory is passed in the environment
230 to run as the invoking user; the default
236 causes verbose logging on standard output.
