NUT package (2.8.0 and below)

dennypage

Notes on executing commands

NUT has command line tools that allow execution of local commands to perform tasks such as a battery test or set variables in the hardware of the ups. Information on these tools can be found here:

http://networkupstools.org/docs/man/upscmd.html
http://networkupstools.org/docs/man/upsrw.html

In order to use these tools, a privileged NUT user is required. The NUT package automatically creates an administrative user for this purpose. The username is “admin”, and the password can be found in /usr/local/etc/nut/upsd.users. Note that the password is automatically generated, and changes each time the NUT configuration is changed or the system is rebooted.

Be careful with these commands. :)

I didn't notice that this update went through, so I never removed the old version.

I thought it was broken at first, because I kept going to "Services -> NUT" and I kept getting an nginx error, didn't realize that it had moved to "Services -> UPS"

Is there any way to remove the old "Services -> NUT" menu entry? It seems stuck there.

If you are comfortable editing the config file, you can remove the old menu section. It looks like this:

<menu>
<name>NUT</name>
<tooltiptext>Set Network UPS Tools settings.</tooltiptext>
Services
<url>/ups_status.php</url>
</menu>

Be very careful editing the config file, and back up the config first.

Thank you,

I have no problem editing xml config files (though the pfsense version of vi is awful), but where is the file?

Or is it more appropriate to save a backup config to my workstation, edit the config, and then upload the edited version?

You can download/edit/upload if you are okay with a firewall reboot. Alternatively, you can ssh in and use viconfig.

mattlach, did you get your issue resolved?

Just a note I was getting "Driver not connected" errors that wouldn't go away until I rebooted.
Works fine now.

Backstory:
After install, Nut picked up an old (and correct) config - Local USB & usbhid.

It kept failing w/ the following errors:
Poll UPS [APC] failed - Driver not connected
Can't connect to UPS [APC] (usbhid-ups-APC): No such file or directory.

I followed every suggestion here and other BSD (ie: NAS) threads.

None of that helped but a reboot put everything right.
I still appreciate everyone's input though.

Below is just for ref:

Original config:

                <nut><config><type>local_usb</type>

                                <upsmon_conf><extra_args></extra_args></upsmon_conf></config></nut>

Do you mean to say that you install a new version of the NUT package? Both configs you posted are are from the new version of the package. Neither is from the old package.

From a UPS driver point of view, the two configs are identical. The addition of RUN_AS_USER in upsmon_conf has no effect on the driver (usbhid-ups). It's only use is have the monitor (upsmon) run as root in order to work around an issue sending email with a TLS connection, which you are not using. Unless you are planning to use email with a TLS connection, you should remove this directive.

It went like this.
I installed Nut from the package manager. After install, Nut said it found an old config and would use that.
That's when I started getting the driver errors. I did some poking around, checked out the Nut section of config.xml. That's what I posted as my original config.

Today, I went into a config.xml backup from June and the Nut config section there is in the older format.

		 <nut><config><monitor><powerdown><allowaddr><allowuser>fakeuser</allowuser>
				<allowpass>fakepass</allowpass>
				<name>APC</name>
				<driver>usbhid-ups00</driver>
				<port>auto</port>
				 <upstype><cable><snmpname><snmpaddr><snmpcommunity><snmpversion>v2c</snmpversion>
				<snmpmib>ietf</snmpmib>
				 <snmpfreq><snmpdisabletransfer><remotename><remoteaddr><remoteuser>fakeuser</remoteuser>
				<remotepass>fakepass</remotepass></remoteaddr></remotename></snmpdisabletransfer></snmpfreq></snmpcommunity></snmpaddr></snmpname></cable></upstype></allowaddr></powerdown></monitor></config></nut>

I'm assuming the new ver of Nut rewrote my config, sometime after install.

Okay. I tried that after reading a github post about perm issues w/ Nut & was ready to throw spaghetti at the wall.
(ref: https://github.com/rockstor/rockstor-core/issues/1073)

I'll get rid of RUN_AS_USER.
Thanks for the input.

It wrote the new config when you pressed the save button on the Settings page. This is also when the service starts.

I noticed the APC UPS plugged in via USB seems to stay connected for a few days then shows up as offline. I can reload the service and still doesn't work but if I physically unplug it and plug it back it works again.

Not sure what to tell you about this one. It sure looks like a USB connectivity issue. Is there a USB hub or anything you can remove? Another USB connector on the MB you can try? Another cable perhaps?

Yes, I'm shooting in the dark here. :)

It could be a issue with vmware passthrough.. Ill try another port and see if I have the same issues with a windows vm.

Thanks

Hey Dennypage,

I just switched from an older server to a newer server. Older server was running Pfsense 2.3.1 running a much older version of NUT. Backed up the configuration file, installed Pfsense 2.3.2 and restored the configuration file. I then installed the NUT package (Which is now 2.7.4_2) and now the service runs, and the UPS option is under the services menu, but the NUT option is still under the services menu. Is this option supposed to work? All it gives me is "404 Not Found nginx". The UPS tab also doesn't have the fancy bar graphics the older NUT package has. Is this supposed to be under the NUT tab? How do I fix it?

dennypage

I'm looking at how to automatically remove the old Services / NUT menu item. In the interim, this tells you how to do it manually:

@frozensteel:

The UPS tab also doesn't have the fancy bar graphics the older NUT package has.

Both the old and the new NUT package have the same two bar graphs, UPS Load and Battery charge.

In the new package, you will find them on the status page (Services / UPS / Status). This page also shows full detail of what is reported by the NUT driver for the UPS. There is also a UPS Status widget for the dashboard which provides a abbreviated status listing including the two bar graphs.

frozensteel

So I did what you said and removed the following:


<menu>

<menu>
			<name>NUT</name>
			<tooltiptext>Set Network UPS Tools settings.</tooltiptext>
			Services
			<url>/ups_status.php</url>
</menu>

Restored only the package information (since my configuration has changed since this configuration file was used) and it worked like a charm.

However, this is the output I get from UPS Status:

![](https://s22.postimg.org/7ll45jiap/ups_status.png)

I wish it looked like the older version which was like this:

![](https://doc.pfsense.org/images/0/0d/Nut-status-example.png)</menu>

dennypage

The reason that you are not seeing bar graphs for load and charge is because they are not being reported for your UPS. The fields battery.charge and ups.load are missing from the UPS Detail section.

Best guess is that you want a different mib. I would try explicitly setting the ietf mib and see what it shows.

https://forum.pfsense.org/index.php?topic=115349.msg649477#msg649477

dennypage

Another indication that something may be wrong with the mib is that your UPS has a runtime of 136 hours. :)

frozensteel

Man do I want to buy you a beer! Added mibs=ietf to the "Extra Arguments to driver" field, saved it and BOOM!

That about wraps up all the issues!

Thanks :D
