       upsd.conf - Configuration for Network UPS Tools upsd


       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.


       "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

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

               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.
