[Nut-upsuser] Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon ?

[Theo G. Kanter]

Using the HOWTO in
http://keystoneit.wordpress.com/2006/09/25/network-ups-tools-nut-on-ubuntu/
I installed nut on an Ubuntu Edgy LAMP Server with an Eaton Powerware 5110
attached to it via usb. But nut fails to start properly (see the error
message "Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon"
below). It then complains about communication with the UPS being lost
("UPS upsl at localhost is unavailable").

I wonder whether this communication error message may be related to the
howto assuming that a user 'upsl' exists, while 'nut' only configures a
user 'nut'. 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.
Below I included the configuration files (found in /etc/nut/*)
Please advise me on how to deal with both these issues.


# upsdrvctl start
Network UPS Tools - UPS driver controller 2.0.4
Network UPS Tools - BCMXCP UPS driver 0.10 (2.0.4)

Model = POWERWARE UPS    1000VA
Firmware = 00.50
Shutdown delay =  120 seconds
Shutdown delay longer than battery capacity when Low Battery warning is
given. (max 60 seconds)
# /etc/init.d/nut start
Starting Network UPS Tools: (upsdrvctl failed) upsd upsmon.
