[Nut-upsuser] Ubuntu server won't restart

[Erik Hjertén]

Hi all

I have a simple setup:
Ubuntu 9.04 server
APC Back-UPS ES-700 connected with USB
nut installed from packages (apt-get install nut). I guess that makes it 
version 2.4.1 ?

The problem:
When issuing: upsmon -c fsd I get a messages that the server will halt, 
and it does. But it won't restart again.

I have set the BIOS to always power on, and this works fine when if I 
just cut the power and turn it back on without the UPS connected.

If I understand this correctly the script /etc/init.d/halt is supposed 
to poweroff the UPS to cut the power to the server rather than letting 
it halt gracefully, and in that way make use of the BIOS power setting? 
I supect that this doesn't happen in my server and now I need help 
trouble shooting this.

My configurations files are as follows:

/etc/nut/nut.conf:
MODE=netserver

/etc/nut/ups.conf
[UPS]
driver = usbhid-ups
port = auto

/etc/nut/upsd.users
[zem_mon]
         password = password
         allowfrom = localhost
         upsmon master

[monuser]
         password = password
         allowfrom = local
         upsmon master

/etc/nut/upsmon.conf
MINSUPPLIES 1
SHUTDOWNCMD "/sbin/shutdown -h +0" #also tried "/sbin/shutdown -P +0" here

DEADTIME 15
POWERDOWNFLAG /etc/killpower
RBWARNTIME 43200
NOCOMMWARNTIME 300

MONITOR UPS at localhost 1 zem_mon password master

in /var/log/daemon.log I have:
Feb 19 20:24:25 hactar upsmon[5328]: Signal 10: User requested FSD
Feb 19 20:24:25 hactar upsd[5324]: Client zem_mon at 127.0.0.1 set FSD on

Feb 19 20:24:41 hactar usbhid-ups[5322]: Signal 15: exiting

that seems to be UPS related.

Last message in /vat/log/syslog is:
Feb 19 20:24:41 hactar exiting on signal 15
  which seems to be a proper halt?

I'm quite stuck now so any pointers on how to troubleshoot is most 
appreciated.

Kind regards
