No, A runs the driver, plus upsd with LISTEN <IP of A>. If A needs to shut down based on its own UPS (the usual scenario), then it needs to run upsmon connecting to A's IP or localhost. B runs upsmon, connecting to A. 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 -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
