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 at 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.
