[Nut-upsuser] Can Not Get UPS to Turn Off After System Shutdown

[richjunk at pacbell.net]

I just installed NUT on a new Linux (Gentoo) system. Most things work,
(notification after 10 seconds on battery, notification and system
shutdown after 100 seconds on battery.) However I can't seem to get the
UPS (an Eaton 5SC1500) to turn itself off after the Gentoo system shutdown.

This is the shutdown command I am using in /etc/nut/upsmon.conf:

SHUTDOWNCMD "/usr/sbin/upsdrvctl shutdown Eaton5SC1500 ; /sbin/shutdown
-h +0"	

The /etc/shutdown part works. The UPS name, Eaton5SC1500, is correct
because the command 'upsc Eaton5SC1500' lists the current parameters of
the ups.

Here is part of /var/log/messages during my last test "power outage":

Jul 26 19:08:57 run-public upssched[4923]: Event: timeshutdown
Jul 26 19:08:57 run-public upssched-cmd[4940]: The UPS has been on
battery for 100 seconds -- shutting down
Jul 26 19:08:57 run-public upsmon[4897]: Signal 10: User requested FSD
Jul 26 19:08:57 run-public upsmon[4897]: FSD set on UPS

shutdown
Jul 26 19:08:57 run-public upsmon[4897]: Auto logout and shutdown

Any idea on what is causing that ERR ACCESS-DENIED message?

Running upsdrvctl in test mode doesn't tell me much:

# /usr/sbin/upsdrvctl -t shutdown Eaton5SC1500
Network UPS Tools - UPS driver controller 2.7.4
*** Testing mode: not calling exec/kill

If you're not a NUT core developer, chances are that you're told to
enable debugging
to see why a driver isn't working for you. We're sorry for the
confusion, but this is
the 'upsdrvctl' wrapper, not the driver you're interested in.

Below you'll find one or more lines starting with 'exec:' followed by an
absolute
path to the driver binary and some command line option. This is what the
driver
starts and you need to copy and paste that line and append the debug
flags to that
line (less the 'exec:' prefix).
