Do you mean that B does not need to run upsd? Then how does B know which IP to connect with? Does upsmon read upsd.conf, too? I ran like this, and upsmon printed: # upsmon Network UPS Tools upsmon 2.6.3 UPS: MY_UPS@localhost (master) (power value 1) Using power down flag file /etc/killpower Just like if there is no any upsd running in my whold workspace. > >In this case, A is the master, and B is the slave, as described here: > >http://www.networkupstools.org/docs/man/upsmon.html#_ups_definitions > >-- Andrew 2012-03-19
