upsd.conf

UPSD.CONF(5)							    NUT Manual							      UPSD.CONF(5)

NAME

       upsd.conf - Configuration for Network UPS Tools upsd

DESCRIPTION

       upsd uses this file to control access to the server and set some other miscellaneous configuration values. This file contains details on
       access controls, so keep it secure. Ideally, only the upsd process should be able to read it.

CONFIGURATION DIRECTIVES

       "MAXAGE seconds"
	   upsd usually allows a driver to stop responding for up to 15 seconds before declaring the data "stale". If your driver takes a very
	   long time to process updates but is otherwise operational, you can use MAXAGE to make upsd wait longer.

	   Most users should leave this at the default value.

       "STATEPATH path"
	   Tell upsd to look for the driver state sockets in path rather than the default that was compiled into the program.

       "LISTEN interface port"
	   Bind a listening port to the interface specified by its Internet address. This may be useful on hosts with multiple interfaces. You
	   should not rely exclusively on this for security, as it can be subverted on many systems.

	   Listen on TCP port port instead of the default value which was compiled into the code. This overrides any value you may have set with
	   configure --with-port. If you don't change it with configure or this value, upsd will listen on port 3493 for this interface.

	   Multiple LISTEN addresses may be specified. The default is to bind to 127.0.0.1 if no LISTEN addresses are specified (and ::1 if IPv6
	   support is compiled in).

	       LISTEN 127.0.0.1
	       LISTEN 192.168.50.1
	       LISTEN ::1
	       LISTEN 2001:0db8:1234:08d3:1319:8a2e:0370:7344

	   This parameter will only be read at startup. You'll need to restart (rather than reload) upsd to apply any changes made here.

       "MAXCONN connections"
	   This defaults to maximum number allowed on your system. Each UPS, each LISTEN address and each client count as one connection. If the
	   server runs out of connections, it will no longer accept new incoming client connections. Only set this if you know exactly what you're
	   doing.

       "CERTFILE certificate file"
	   When compiled with SSL support, you can enter the certificate file here. The certificates must be in PEM format and must be sorted
	   starting with the subject's certificate (server certificate), followed by intermediate CA certificates (if applicable_ and the highest
	   level (root) CA. It should end with the server key. See docs/security.txt or the Security chapter of NUT user manual for more
	   information on the SSL support in NUT.
