NUT notifications not working on pfsense+

@austin-0 While we're at it, we might as well just do this:

grep notify_monitor /var/log/system.log

This will include the prior attempts as well.

I replaced the email address with ----- in the output for privacy reasons. It was the correct email though. I also did get the notification email when running this test.

Actually now it is spamming the email with the "this is a test" message.

Meaning you received a notification from NUT saying that the UPS was not available? There are two successful indications in there.

Austin 0

And it was failing to get the UPS status until reseated the cable, and restarted the nut service.

Austin 0

@dennypage Yes however last time we tried that I also got the notifications when running the command. I just don't get them when I disconnect the UPS, or it switches to battery.

Ah... there we go. See this Redmine entry for a patch.

@dennypage Thank you. We are currently live streaming. So it's not a good time to be installing patches, but once that is done I will try out the patch.

After installing the patch, you may also need to remove the existing notification files. And if a process is hung processing notifications, either kill it or reboot pfSense.

@dennypage Okay so I have never done this before, but from what I can tell I correctly entered th commit ID, but it is telling me it is invalid. What am I doing wrong here?

dennypage

@austin-0 Not sure, but you can try it in URL format:

https://github.com/pfsense/pfsense/commit/c5faa351c1ef6d4555478a7f50b3a16ece7e0b2a.patch

@dennypage Thank you. I was able to install the package, and then rebooted. Notifications are still not being emailed to me when I unplugged the USB cable to the UPS. I did get the notifications for the actual reboot.

dennypage

@austin-0 Can you post the grep output please?

grep notify_monitor /var/log/system.log

Austin 0

@dennypage Well I am no longer there and someone turned off the computer I usually use to remote in. So I won't be able to do this until Friday or Saturday.

dennypage

@austin-0 Okay, I just tested that patch. The effect is that all non root notifications silently fail. I've reached out to @jimp in the Redmine discussion.

In the interim, it appears that the only way you will be able to make it work is to have NUT run as root. You can do this by adding the line

RUN_AS_USER root

to the "Additional configuration lines for upsmon.conf" section in Services / UPS / Settings / Advanced settings.

@dennypage I am not getting email notifications from NUT either, and hope you can point me in the right direction.

I have a Cyberpower UPS plugged into my pfSense box with a UPS, and the UPS is recognized fine within the GUI. If it is on battery, I get an alert in the GUI, but do not get an email through the normal pfSense process.

I added the additional configuration to run NUT as root, and rebooted, but that did not work. See below for my upsmon.conf and nut_email.php files, and please let me know what I am missing - thank you!

@pdavis @dennypage Sorry, Denny, scratch that last request - I just got the emails following the change to have NUT send as root, so all set!

Thank you

dennypage

@pdavis Glad you have it working. I'm hoping that the requirement to run as root is temporary.

Austin 0

@dennypage Well hopefully this works for me as soon as I get a chance to test it. I am curious as to what the security impacts of running the process as root would be. Would it not be better to change the access to whatever file nut needs access to?

dennypage

@austin-0, @pdavis I have a PR in which will restore notification functionality. You can find it here if you want to follow it, or if you just want to grab the revised version of nut_email.php.
