ReadyNAS as Network UPS Tools (NUT) client?

Thanks! OK; added the SSH add-on; found I'd need to reboot to enable it... deferred that (as it's disruptive). Saw (yesterday) that RAIDiator 4.2.27 was now available, so incorporated that update with my regular weekly updates of Everything Else (that was going to be disrupted anyway); on reboot, was reminded that SSH was now available. Right. So, referred to above "viewtopic..."; created /etc/not/.orig & copied all the files from /etc/nut there. (Would have use RCS....) Anyway: referred to the cited post & a FreeBSD machine that's acting as a "nut" slave; copied MONITOR line in upsmon.conf; also edited upsd.users to conform to working machine.

But how do I (re-)start upsmon? Available options on Web interface ("Frontview?) for UPS Configuration don't really apply (and selecting them overwrites the above). On my FreeBSD box, I'd "service nut_upsmon restart" to do this... but I'm unfamiliar with Linux.
