NUT is set up on all the clients and it all works like a charm - in so much as everything shuts down during a power-fail. However, I would also like to be able to issue 'instant commands' to the UPS from one of the clients. Checking what commands are supported with upscmd -l UPS@my_nas_ip_address I initially got this list back:
Instant commands supported on UPS [UPS]:
beeper.disable - Disable the UPS beeper
beeper.enable - Enable the UPS beeper
beeper.mute - Temporarily mute the UPS beeper
beeper.off - Obsolete (use beeper.disable or beeper.mute)
beeper.on - Obsolete (use beeper.enable)
load.off - Turn off the load immediately
load.off.delay - Turn off the load with a delay (seconds)
load.on - Turn on the load immediately
load.on.delay - Turn on the load with a delay (seconds)
shutdown.return - Turn off the load and return when power is back
shutdown.stayoff - Turn off the load and remain off
shutdown.stop - Stop a shutdown in progress
test.battery.start.deep - Start a deep battery test
test.battery.start.quick - Start a quick battery test
test.battery.stop - Stop the battery test
To issue any of the above commands required adding a user with the appropriate priveledges so I edited /etc/nut/upsd.users on the NAS to give user 'commander' access to all instant commands:
[monuser]
password = pass
upsmon master
[commander]
password = pass
instcmds = all
Then issuing upscmd -u commander -p pass UPS@my_nas_ip_address beeper.disable from any client stops the beep. Cool.
However, while this did indeed work fine to begin with, on re-starting the ReadyNAS I find that the commands are no longer listed:
Instant commands supported on UPS [UPS]:
and somehow the /etc/nut/upsd.users file had been altered as follows:
[monuser]
password = pass
upsmon master
[commander]
password = pass
upsmon slave
Not beleiving it could be any fault other than my own, I put the user priveledges back in the file and tried again. On re-boot the file reverted once again. What shenanegans are going on to do this - and how can I prevent it? Also, where did the list of instant commands go?
