NUT package (2.8.0 and below)

I'm confused. I was able to recreate the power race problem. Are you saying that this happens with a very low probability that makes it not worth applying the workaround? Sorry, I know I'm persistent but I'm just into the nitty-gritty details.

EDIT:

Also, do you have any ideas about this? https://forum.netgate.com/topic/109510/upsmon-parent-process-died-shutdown-impossible/5 . I'm encountering the same issue every now and then.

@dennypage

Would you be able to continue helping me? Thanks.

@kevindd992002

I’m traveling, so it’s a bit hard atm. Not sure what additional help you need. Not sure what you tested was the issue referred to in the link. Regardless, offdelay and ondelay are likely what you need to look at.

@dennypage

Sorry.

So basically, I wanted to solve the power race problem wherein the UPS acts weird when the mains comes back exactly during its shutting down phase. There's already a script written in NUT's FAQ page but you mentioned that I don't need to do that and insteast just concentrate on ondelay and offdelay. I'm confused why I don't need to solve the power race problem according to what you said. What's the difference between implementing that script and implemnting off/ondelay?

As for the link I posted, that's regarding the upsmon parent process died error message that's being sent through email notification. I haven't gotten it in a few days now but was wondering what you thought about that since you replied to that old thread at one point.

@kevindd992002

The workaround you reference indicates that it is for dealing with contact closure (dumb) UPS units. But you don’t have one of those.

It’s unclear to me what you have experienced. The nut users list is a better place to seek help with core nut behavior.

I have a TrippLite ECO 850 LCD. The UPS is about 4-6 months old, has a 100% capacity still, and has been working flawlessly. It's ECO mode is tured off.

I gracefully rebooted my pfSense three days ago. Since then, I've been receiving the following notices every 10 minutes. I get the first one and then about 5 seconds later I get the second one. Then 10 minutes later I get the same two messages again. When this started, I checked and there was an update for NUT that I installed. This didn't help. I've rebooted pfSense again and that didn't help.

Is there additional information I can supply or steps I can try to resolve this issue?

@pfserik
Most often this is cause by flakey USB connectivity. You kind of have to use the cable that came with the unit, so unless you have another unit to swap cables with it's kind hard to check that. If you have multiple USB hubs in the box, try one of the ports connected to a different hub. Lastly, if you you can try add/remove of an external hub.

It could also be a bad UPS, but I think that unlikely. When these unit fail, it is usually complete. Worth running a self test however. Note of caution: although undocumented, when you run a self test the ECO sockets get turned off even if you have ECO disabled. I found that out the hard way.

Btw, I assume you are running 2.4.3-RELEASE-p1, yes?

Hi, I am currently having trouble accessing my SNMPv3 enabled APC SmartUPS 3000 using NUT 2.7.2 downloaded from package and NMC AP9631 on CentOS 7

My ups.conf

[ups6]
driver = snmp-ups
port = ups6.domain.name
snmp_version = v3
secLevel = authPriv
secName = ups6
authProtocol = MD5
privProtocol = AES
authPassword = <secret>
privPassword = <secret>
pollfreq = 15

When I run /usr/sbin/upsdrvctl start I get

# /usr/sbin/upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.2
Network UPS Tools - Generic SNMP UPS driver 0.72 (2.7.2)
No supported device detected
Driver failed to start (exit status=1)

But when I switch it to SNMPv1, it works
ups.conf

[ups6]
driver = snmp-ups
port = ups6.domain.name
snmp_version = v1
pollfreq = 15

# /usr/sbin/upsdrvctl start
Network UPS Tools - Generic SNMP UPS driver 0.72 (2.7.2)
No matching MIB found for sysOID '.1.3.6.1.4.1.318.1.3.27'!
Please report it to NUT developers, with an 'upsc' output for your device.
Going back to classic MIB detection method.

Can someone help me out with this please

This isn't the forum you are looking for. This forum relates to pfSense, which is a firewall distribution, and this thread is about the NUT package for pfSense. No relationship to NUT on CentOS. You should seek help in either the CentOS or NUT forums/mailing lists.

Before you ask them for help however, you probably want to upgrade. The version of NUT you are using, 2.7.2, was obsolete more than 3 years ago. The current version is 2.7.4, which was released over 2 years ago. Just sayin'.

Oh oops I will do that then.

The newest release for CentOS7 is 2.7.2-4. https://pkgs.org/download/nut
Should I just download 2.7.4 from somewhere?

Derelict · Sep 15, 2018, 9:53 PM

Again, a question for the CentOS folks.

dennypage · Sep 17, 2018, 3:31 PM

@derelict That I've noticed, OP posted here, on the NUT users list, and also on Reddit. I expect he found a CentOS board to post on as well. Spray and pray.

Sheesh, you don't have to be so mean. I was researching this issue for over a day, so decided to go on forums to ask. Might as well post on many, since not all of these are super active. I saw one person having the same issue in this same thread and ended up using v1, and saying he will figure out v3, and not updating his post. @dennypage also replied to that comment saying it was a misonfiguration in the .config file, but it is just that NUT doesn't support SNMPv3 on the AP9631 APC UPS NMC.

I hope i didn't annoy you all with my question, and hopefully what I found out will help users in the future.

@kaeny123 I wasn't being mean dude. You should understand that the approach you took is considered to be inappropriate and does not incline people to help you.

How so? I am fairly new to this, maybe I don't understand the etiquette. I apologize for any rude behavior on my part, I would like to know so I dont repeat the same mistake

dennypage · Sep 17, 2018, 4:38 PM

@kaeny123 Given that you are trying to hook up a UPS to a Linux system, and are trying to using SNMPv3 (!), I would have expected you to have some computer awareness. If not, there should be hundreds if not thousands of folk at Georgia Tech that would be able to help you.

That said, I'll try a simple analogy. Coming into a support forum for a firewall distribution based on FreeBSD and asking a question about the NUT package on CentOS is akin to going into a BMW forum and asking a question about tire recommendations for a Honda. It doesn't matter that both cars use tires, the question is completely out of scope for the audience.

Also, you had already asked your question upstream in the NUT users list. If the terms upstream and downstream don't make sense, ask some of the people around you.

Well, other than the blatant condescending tone, I understand what you mean. I was being modest when I said I was new to this. And it turns out my issue wasn't computer knowledge related. I should've checked the forum topic first, this just came as a result of googling.

Thank you for your replies, they were very helpful :)

Dial it back son. You asked me to explain so you could avoide the same mistake in the future, and I did. Computer awareness meant understanding the difference between CentOS and a firewall distribution based on FreeBSD. This was not indented to be condescending.

Hello all,

Trying to get NUT working with a local-usb apc back-ups pro (on pfsense ).

ugen0.2: <American Power Conversion Back-UPS RS 900G FW879.L4 .I USB FWL4> at usbus0

I've configured the pfsense package gui with a random name, driver usbhid-ups and "Local USB" as type. Nothing else.

cat /usr/local/etc/nut/ups.conf
[APC_Back-UPS_PRO_900]
driver=usbhid-ups
port=auto

Nothing works and I see:

Oct 19 16:33:25	upsd	15243	User local-monitor@::1 logged into UPS [APC_Back-UPS_PRO_900]
Oct 19 16:33:25	upsmon	14608	Poll UPS [APC_Back-UPS_PRO_900] failed - Driver not connected
Oct 19 16:33:25	upsmon	14608	Communications with UPS APC_Back-UPS_PRO_900 lost
Oct 19 16:33:30	upsmon	14608	Poll UPS [APC_Back-UPS_PRO_900] failed - Driver not connected
Oct 19 16:33:30	upsmon	14608	UPS APC_Back-UPS_PRO_900 is unavailable
Oct 19 16:33:35	upsmon	14608	Poll UPS [APC_Back-UPS_PRO_900] failed - Driver not connected

Could someone please point me in the right direction?
(the same worked out of the box with apcupsd)

Thanks

dennypage · Oct 19, 2018, 4:33 PM

The messages you are looking for are those from process "usbhid-ups". You can find them by going into the system logs (Status / System Logs / System / General), selecting the funnel icon, and then inputing "usbhid-ups" in the Process field.

Perhaps to short circuit the process, have you rebooted or unplugged / replugged the UPS since you installed it? If not, it's likely a permissions problem.
