RedHat 9 (Linux i386) - man page for upsd (redhat section 8)

UPSD(8) 			     Network UPS Tools (NUT)				  UPSD(8)

       upsd - UPS information server

       upsd -h

       upsd -V

       upsd [-p port] [-t port] [-i interface] [-f] [-u user] [-c command]

       upsd  is  responsible for serving the data from the drivers to the clients.  It listens on
       network ports and delivers the data from the state files or  shared  memory  used  by  the
       drivers.   It  also  conveys  administration messages from the clients such as upsrw(8) or
       upscmd(8) back to the drivers.

       This program is essential, and must be running at all times to actually make any  use  out
       of the drivers and clients.

       Controls  in  the  configuration  files	allow  you to limit access to the server, but you
       should also use a firewall for extra protection.  Client processes such as upsmon(8) trust
       upsd for status information about the UPS hardware, so keep it secure.

       -c command
	      Send command to the background process as a signal.  Valid commands are:

		   reload - reread configuration files
		   stop - stop process and exit

       -f     Stay in the foreground for testing.

       -h     Display the help text.

       -i interface
	      Bind the listeners to the interface specified by its internet address.  This may be
	      useful in situations with internal and external interfaces on the same host.

       -p port
	      Run the UDP and TCP listeners on that port.  This overrides any value you may  have
	      set  with  'configure  --with-port'.  If you don't change it with configure or this
	      switch, upsd will listen on port 3493.

       -t port
	      Run just the TCP listener on that port.  If you want the TCP and UDP  listeners  on
	      different ports for some reason, use -p, then follow it with -t.

       -u user
	      Switch  to user user after startup if started as root.  This overrides whatever you
	      may have compiled in with 'configure --with-user'.

       -V     Display the version of the program.

       upsd can reload its configuration files without shutting down the process if you send it a
       SIGHUP  or  start it again with '-c reload'.  This only works if the background process is
       able to read those files.  Since upsd gives up root after reading the files for the  first
       time, this may not always be the case.

       If  you think that upsd can't reload, check your syslogs for error messages.  If it's com-
       plaining about not being able to read the files, then you need to adjust  your  system  to
       make it possible.  Either change the permissions on the files, or run upsd as another user
       that will be able to read them.

       DO NOT make your upsd.conf world-readable, as it contains passwords and some  evil  person
       could pretend to be your master upsmon and command your systems to shut down.

       upsd  expects  the  drivers  to	update	their status regularly.  By default, they must be
       refreshed every 15 seconds.  After that, the UPS is declared "stale" and no more  informa-
       tion will be provided to the clients.

       If upsd complains about staleness when you start it, then either your driver or configura-
       tion files are probably broken.	Be sure that the driver is actually running, and that the
       UPS definition in ups.conf(5) is correct.

       The  general  upsd  configuration file is upsd.conf(5).	The administrative functions like
       SET and INSTCMD for users are defined and controlled in	upsd.users(5).	 UPS  definitions
       are found in ups.conf(5).
