       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 interface.

           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.
