NUT package (2.8.0 and below)

It sounds like SNMPv3 may not be properly configured/functioning in NUT. Can you post the contents of /usr/local/etc/nut/ups.conf please?

I am going to find an SNMPv3 client and try replicate this in a moment. If a different v3 client fails in the same way the issue is with AP9631.

If it doesn't then there may indeed be a NUT issue. Maybe it has some routine to check SNMPv1 availability before anything else, even if only SNMPv3 is needed.

I realize the credentials are in there but it's a sandbox setup so this is not really a concern. My full, unedited /usr/local/etc/nut/ups.conf:

retrydelay=30
maxretry=20
snmp_version=v3
privProtocol=AES
authProtocol=SHA
secName=pfSense
authPassword=VtwHzSj6XQlmp9OFFa28NJcUL93qq5zZ4
privPassword=TpWsICXWm4CeKtwUehtvcBpDnBW0KZCC

[S10-AP9631]
driver=snmp-ups
port=172.16.10.5
snmp_timeout=2
snmp_retries=10

SNMP parameters are part of the UPS specification. As such, they go in the "Extra Arguments to driver" rather than in the "Additional configuration lines for ups.conf" section. The advanced section is only for Global Directives (see ups.conf), and anything that is not recognized as a global directive is ignored by NUT. I know it's confusing, but it's how NUT's configuration works. Anything that comes from the driver man page (snmp-ups in your case) goes into Extra Arguments to driver.

Edit: So it seems it was using SNMPv1 all along due to my mis-configuration resulting in the SNMPv3 stuff being ignored. There is no bug. Now that I have the correct structure in ups.conf it is indeed trying to connect SNMPv3 but it is not authenticating. The AP9631's built in baby IDS keeps sending me notifications now that there are failed SNMPv3 authentications from the pfSense IP.

I will switch her back to SNMPv1 for now and troubleshoot my SNMPv3 setup with qtmib

That makes sense. For what it's worth, most people use a read-only SNMPv1 group for UPS monitoring. There isn't any sensitive information in the stream.

The docu said a write community is needed to facilitate shutdowns. I wanted the UPS and NUT to coordinate that NUT will shut down pfSense when there's not much runtime left and then tell the UPS to shut off the outlet in x minutes and come back up when AC power is restored and battery has at least y % charge.

Otherwise pfSense will just shut down and stay down until someone presses the power button or the BIOS power on time is reached.

Ah, yes. Needing write permission to kill power makes sense. Note that the pfSense NUT package version 2.7.4_5 does not support issuing the final power kill order. This will come with NUT package 2.7.4_6 which requires pfSense 2.4.3.

xx_robot_xx

Hello,

How do you configure power-kill after shutdown? I have pfsense 2.4.3 and latest version of nut..

dennypage

Power kill is enabled automatically with pfSense 2.4.3 and 2.7.4_6 of the NUT package. No configuration necessary.

Hello,

I have a TrippLite Smart 1300VA unit connected via USB. dmesg does show it connected. This model is also one listed in NUT to use the USB driver (not the legacy TrippLite driver). I got readings from it very briefly last night when setting it up, but also a bunch of messages in the log about the data being stale. This was on pfSense 2.4.1.

Now it doesn't work at all. I upgraded to the latest NUT package. No dice. I upgraded pfSense to 2.4.3… no dice.

All I get is this in the status logs:
Apr 4 14:57:20 upsd 97125 User monuser@::1 logged into UPS [main]

pfSense has been rebooted twice now. Once for the 2.4.3 upgrade. And another time after I removed NUT package and reinstalled NUT package. NUT is version 2.7.4_6.

Please run "usbconfig dump_device_desc" and post the output. Also, can you post the contents of /usr/local/etc/nut/ups.conf please? And lastly, the exact model number of the UPS.

Btw, where did you see the note about using the usbhid-ups vs. the tripplite_usb driver? I didn't find a Tripp Lite 1300VA model in the NUT HCL…

kjstech

Ok the model number is SMART1300LCDT. I was at work when I posted and I forgot the exact model number. I was told I can use usbhid-ups from here: http://networkupstools.org/ddl/Tripp_Lite/SMART1300LCDT.html

I also wanted to add, I tried specifying more detail in the ups.conf like the port and description, and also change the poll interval.

Still nothing.

It almost seems to be maybe a permissions problem? But even if I try to run it as root it shows this:

The "retrieving string failed" is something I haven't seen before and would seem problematic. First thing I would suggest is trying a USB port on the other bridge chip. I would also test a different cable.

kjstech

Ok I did try another USB port and its the same results.

I'm at work now, I can try a new USB A to B cable. There's 6 ports on the back, 2 on the front. Its a Dell Optiplex 390. It doesn't appear to have USB 3.0 - at least none of the ports are blue. I could also throw in a USB 3.0 PCIe card if none of the onboard ports work. TrippLite's website does not appear to have any firmware for this model. If it did I would plug into my Windows laptop temporally and update it.

It looks like all the ports are USB 2.0. The UPS itself is a low speed USB device, so you are using the internal compatibility bridge anyway.

Btw, if you have any other USB devices connected, you might want to disconnect them while you diagnose your UPS issue.

kjstech

Fortunately, I have no other USB devices connected, as its running headless. Just a mini-tower with two ethernet cables, power, and now as of this week, a USB cable to a UPS.

kjstech

I tried another port and cable. It still seems to think it’s in the same port 0.3.
Still see the retrieving string failed. Still not able to monitor UPS in pfSense GUI.

I’m not sure what the issue is.

Until you have the USB issue figured, I would disable the NUT service in pfSense.

On the USB bus, the second bus may the front connectors. It's worth a shot. Normally, I recommend against USB hubs, but it's also worth a try to put a (high quality) hub between the host and the UPS to see if that helps.

Btw, did you ever try the tripplite driver?

kjstech

Yes I tried the tripplite driver and I get the same result.

I tried the back USB ports. I did't try the front because I was trying to keep it a clean install without cables coming out of the front. I could try that though.

I have some usb hubs I could try, it would be strange solution but I'm willing to try it.

The only thing I haven't tried is connecting a monitor and keyboard up to it and booting into the BIOS to see if there's anything specific to USB in there.

I have an APC BackUPS 550 I could also try. I wanted the TrippLite on this unit though because it's a higher capacity, but for experimentation purposes I can switch it.
