NUT was working fine but I had to restore some configuration in pfsense 2.4.4-RELEASE-p2. After that I loaded the NUT package but it fails to start. I've tried rebooting, reloading package, etc.

I removed nut and tried apcupsd and it works so I removed that and loaded nut again but it fails to load.

I can't find logs or any idea why it would fail when it worked before. Is it odd that the package is 2.7.4_7 but has a dependency of nut_2.7.4_8? (I was told on /r/pfsense that was unrelated.)

@stevemac00 Look for entries in the system log (Status / System Logs / System / General) matching either "nut" or "ups". Use the funnel icon to scan.

When I restored configuration for some reason it didn't reconfigure. I did manually and it works again. Probably operator error. Thank you for replying.

I'm using NUT 2.7.4_7 with a APC Back UPS Pro 550 USB but I don't get it to work. I selected the usbhid driver, but I always see in logs:

Apr 16 22:52:07	upsmon	69828	Poll UPS [APC_BackUPS_Pro_550] failed - Driver not connected
Apr 16 22:52:02	upsmon	69828	Poll UPS [APC_BackUPS_Pro_550] failed - Driver not connected
Apr 16 22:50:52	upsmon	69828	Poll UPS [APC_BackUPS_Pro_550] failed - Driver not connected
Apr 16 22:50:47	upsmon	69828	UPS APC_BackUPS_Pro_550 is unavailable
Apr 16 22:50:47	upsmon	69828	Poll UPS [APC_BackUPS_Pro_550] failed - Driver not connected

Any idea?

@mrsunfire What you are looking for is further back in the logs. You're looking for what usbhid-ups says when it starts up. You can force new log entries by restarting the UPS service.

Have you rebooted or unplugged/re-plugged since you installed NUT?

dennypage

@jompigrande No reason I know of for this.

Yes I did. I also reinstalled the NUT package. The apcups package also works fine with the UPS.

@mrsunfire We would be looking for messages from "usbhid-ups" which is the actual driver.

Also, can you also post your UPS config? Either the <nut> section of the config or a screenshot of Services / UPS / Settings. Thanks.

mrsunfire

I don‘t see any log with usbhid-ups.

dennypage

@mrsunfire There definitely should be log entries for "usbhid-ups" when you start the nut service.

Just to make sure you're not hitting a name limit, please change the name of the ups to something simple with no special characters. Something like "myups"

Please post the output of these two files:

/usr/local/etc/nut/ups.conf
/usr/local/etc/rc.d/nut.sh

Thanks.

mrsunfire

@dennypage I changed the name to „UPS“. Still the same error. I don‘t see any logs from usbhid-ups.

OK I got it to work by also using the apcusbd package and setup the NUT package to USB type „Remote apcusbd“. Now I got the widget working!

dennypage

@mrsunfire Please try starting the script by hand using the command:

/usr/local/etc/rc.d/nut.sh start

and post the output.

dennypage

@mrsunfire Uh... you aren't trying to run apcupsd and nut at the same time are you?

mrsunfire

No I was not. But now I am and it works flawless.

dennypage

@mrsunfire You cannot use apcupsd and nut at the same time. They cannot both manage system shutdown.

If you want help to understand the issue with nut, I will help you but you need to disable or delete apcupsd before proceeding.

Otherwise, if you are happy with using apcupsd, you should delete the nut package.

mrsunfire

Why? I just want the widget and nothing else. This works only with NUT and NUT only works with apcupsd right now :)
But yes, I want to find out what the problem is. I will do this tomorrow guided by your help.
Thanks in advance!

dennypage

@mrsunfire Because you cannot have two processes trying to manage system and ups shutdown/restart.

mrsunfire

I don't want to shutdown. I only want the widget. Is there a way to disable the shutdown completely?
