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.
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.
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 127.0.0.1 if no LISTEN addresses are specified (and ::1
if IPv6 support is compiled in).
This parameter will only be read at startup. You'll need to restart
(rather than reload) upsd to apply any changes made here.
UPGRADING FROM OLDER VERSIONS
The ACL/ACCEPT/REJECT mechanism that existed in versions before
nut-2.4.0 has been removed. You'll want to use the LISTEN directive to
limit the addresses the server listens at on multihomed systems. If
this is not fine grained enough, use a firewall.
