[Nut-upsuser] machine not shutting down and connection failures in logs

[Riccardo Magliocchetti]

Hi,

this is my first nut installation, i see lot of connection failure and when i tried
the configuration removing the power chord from the ups i expected tha machine will
power itslef down but this has not happened.

I'm using nut 2.2.2-2 from debian lenny, ups is a mustek powermust 2000 with usb cable.

All config files are root:nut and 640, i've had to add nut user to nut group manually.

ups.conf:
[bongups]
driver = megatec_usb
port = auto
desc "UPS Mustek PowerMust 2000"

upsd.conf:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACL mybox 192.168.10.75/32

ACCEPT localhost
ACCEPT mybox
REJECT all

upsd.users:
[admin]
	password = pass
	allowfrom = localhost
	upsmon master

[monuser]
	password = pass
	allowfrom = mybox
	upsmon master

upsmon.conf:
POWERDOWNFLAG /etc/nut/killpower
MONITOR bongups at mybox 1 monuser pass master
SHUTDOWNCMD "/sbin/shutdown -h +0"

syslog (daemon.log):

Every 3 minutes i get a failure.

ps aux | grep ups:

The zombie will disappear after a few time.
