No. It will complain in case of permissions problems, but this is not what is happening here. > I am new to 'nut' so any hints are welcome. I have no clue why > upsdrvctl fails when I start nut when it first starts properly by itself. You can't start a driver multiple times for the same UPS. So if you ran 'upsdrvctl start', the script '/etc/init.d/nut start' (that will do so also) will fail. You need to run 'upsdrvctl stop' first, if the driver is running already for whatever reason. > # upsdrvctl start > Network UPS Tools - UPS driver controller 2.0.4 > Network UPS Tools - BCMXCP UPS driver 0.10 (2.0.4) You may want to upgrade to the latest stable version (2.0.5), although this doesn't seem to be related to the problem you're having. > # /etc/init.d/nut start > Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon. See above. This script attempts to start the UPS driver through 'upsdrvctl', but since it is already running, this fails. A well behaved startup script would check for a successful startup of the driver and would have terminated here. Why it isn't, is beyond me.
