NUT package (2.8.0 and below)

I‘m having the issue that I get a shutdown loop after the UPS battery is empty.
pfSense shutdown as expected. After power restores the UPD turns on and pfSense boots up. Couple of seconds later the UPS is doing battery check. This seems to trigger pfSense to shutdown again and turns of UPS aswell. This loop continues until I unplug communication to the UPS and wait that battery gets fully charged.
You can see here that the input power is available but the UPS is getting the signal from pfSense to not charge. After couple of seconds pfSense and UPS shutdown.
-
@mrsunfire please post your config. And your UPS model.
-
@dennypage Config is vanilla (no change). UPS is APC Backups Pro 550 via USB.
-
@mrsunfire Hmm... I would have expected there to be some config change, either in the NUT package or in the UPS, as the UPS should not be bringing the load back on that quickly (0%). Nor would I expect it to show "On Line" and "Discharging" like that unless a calibration cycle were underway.
Speaking thereof, have you run a battery calibration recently? Perhaps the battery is dead...
Lastly, can you post the output of upsrw?
-
@dennypage No calibration. I wo der why UPS switches back on battery the moment I connect pfSense.
Whats the command for that output? -
@mrsunfire How old it the UPS and battery?
Please post the output of upsrw. If you aren't familiar with that, you can find examples in this thread.
-
@mrsunfire I was having weird issues in the last and it turned out to be a bad battery not the software.
-
@jonathanlee Yes I already ordered new batteries before continue further testing.
I also did edit upsmon.conf and removed "SHUTDOWNCMD "/sbin/shutdown -h +0"". Unfortunately after reboot this setting is back there. How to proper edit that file? My goal in the first step was to not shutdown the pfSense at all.

Fast answer : you can't.
As the GUI states, this is what gets inserted in that file :And this is what gets inserted upfront by the GUI interface, even when you leave that bloc empty :
/usr/local/pkg/nut/nut.inc line 250->252
( so, edit that file and do whatever you want ^^ )

You can't. If you want to prevent NUT operation (shutdown and everything else), change the UPS Type to disabled until you replace the battery.
-
I have an APC Back-UPS BX2200MI connected and configured in pfSense.
Everything seems to work fine.
But how and where can I customize the shutdown delay?
I want it to turn off when the battery guarantees me no more than 10 minutes of electricity.
If within these 10 minutes the current returns, what happens?
What if pfSense has shut down in the meantime? The BIOS is configured for the PC to turn on when the power returns; is this enough? -

-
@darkcorner If your UPS allows you to, you can configure
battery.runtime.low
to the amount of time you want the UPS to declare a critical condition. Unfortunately, a lot of UPSes don't allow you to configure this. If they do, you should be able to see and adjust the setting with theupsc
command.

Thanks for your answers.The UPS USB cable is connected to pfSense, but it covers multiple PCs/servers that need to shut down automatically.
So, pfSense is the Master of NUT and on these PCs/Servers I'm installing tools configured as NUT Slave.TrueNAS is configured as "Slave" in its NUT service, but it doesn't seem to notice the presence of the Master.
On a Win10 Pro PC I mounted WinNUT-Client and it gives me a login failure error for authentication.
(If it's not the right software, can you suggest me some other client?)For all, the port is the standard one (3493).
In Windows10 I turned off its Windows Defender Firewall.
On pfSense there are two rules in LAN and DMZ for LAN-Net and DMZ-Net which allows any to any with any protocol.
In pfSense, with Diagnostic - Test Ports the port seems open, but from console telnet 127.0.0.1:3493 or (localhost:3493) reports the error "Name does not resolve".
On PC Win10 telnet LAN-NIC-Address:3493 reports error "Could not open connection to host. on port 23: Connection failed"As NUT users I am using both admin and local-monitor with the password present in /usr/local/etc/nut/upsd.users.

This one ?
I'm using several of them, pfSense being the NUT-master. It works.pfSense side :
and
Note : my ups is called 'ups'.
On the Win NUT client side, a PC :
where password = "secret2" as this is "pcrecep1".
I've no particular firewall rules on my LAN, 19.168.1.1 - just one pass-all, so the client connects just fine.

You instructed NUT (pfSense) to listen on what interfaces ?
127.0.0.1 is not reachable from LAN. So
I want NUT to listen on my LAN so I told it to do so :@darkcorner said in NUT package:
On PC Win10 telnet LAN-NIC-Address:3493 reports error "Could not open connection to host. on port 23: Connection failed"
telnet could be a good test.
But telnet uses TCP. Not sure if NUT uses UDP or TCP.A better test : ask the system directly. I know the port, 3493, so :
[22.05-RELEASE][admin@pfSense.local.net]/root: sockstat | grep '3493' root upsd 21699 4 tcp6 2001:470:xxxx:5c0:2::1:3493 *:* root upsd 21699 5 tcp4 192.168.1.1:3493 *:* root upsd 21699 6 tcp6 ::1:3493 *:* root upsd 21699 7 tcp4 127.0.0.1:3493 *:* root upsd 21699 11 tcp6 ::1:3493 ::1:64823 root upsd 21699 12 tcp4 192.168.1.1:3493 192.168.1.33:36453 root upsd 21699 13 tcp4 192.168.1.1:3493 192.168.1.6:58694 root upsd 21699 14 tcp4 192.168.1.1:3493 192.168.1.7:60690 root upsmon 20768 4 tcp6 ::1:64823 ::1:3493
This tells you everything you need to know.
Nut listens on my LAN IPv6, and 192.168.1.1 all port 3493. Protocol is tcp.
PC's (clients) 192.168.1.6 and 192.168.1.7 have an established connection.
Like 192.168.1.33, my syno NAS, using 'monuser' and 'secret' as login ID.
Btw : ok, it listens also on localhost or 127.0.0.1 or ::1 on port 3493, tpc.@darkcorner said in NUT package:
As NUT users I am using both admin and local-monitor with the password present in /usr/local/etc/nut/upsd.users.
True, this information :
will be placed into that file.
Do NOT edit that file yourself, use the GUI.My "/usr/local/etc/nut/upsd.users" file has more info in it.
At the top, I find :[admin] password=be7b490cda2016c2a1fe actions=set instcmds=all [local-monitor] password=e90150cecfe29445f4a3 upsmon master
These are created when you install the package.
Not sure why I should use these. These [admin] and [local-monitor] are probably RTFM items.edit :
By now, you have your clients up and connected.So, bonus time :
The NOTIFYFLAG lines ask nut to spam logs, messages on the console, which can be seen if you are logged in console or SSH.
This one : "NOTIFYCMD /usr/local/sbin/upssched" is special.
You have to make your copy of this file : /usr/local/etc/nut/upssched.conf - take upssched.conf.sample as an example.
My /usr/local/etc/nut/upssched.conf :CMDSCRIPT /root/upssched-cmd.sh PIPEFN /var/db/nut/upssched.pipe LOCKFN /var/db/nut/upssched.lock AT ONBATT * START-TIMER onbatt 15 AT ONLINE * CANCEL-TIMER onbatt online AT LOWBATT * EXECUTE lowbatt AT COMMBAD * START-TIMER commbad 30 AT COMMOK * CANCEL-TIMER commbad commok AT NOCOMM * EXECUTE commbad AT FSD * EXECUTE powerdown AT SHUTDOWN * EXECUTE powerdown
and before you ask : here is my home made /root/upssched-cmd.sh :
#!/bin/sh UPS="ups" STATUS=$( upsc $UPS ups.status ) CHARGE=$( upsc $UPS battery.charge ) CHMSG="[$STATUS]:$CHARGE%" # upssched-cmd --slave -- /usr/bin/logger -i -t upssched-cmd Calling upssched-cmd $1 case $1 in online) MSG="$UPS, $CHMSG - power supply has been restored." ;; onbatt) MSG="$UPS, $CHMSG - power failure - save your work!" ;; lowbatt) MSG="$UPS, $CHMSG - shutdown now!" ;; upsgone) MSG="$UPS, $CHMSG - UPS has been gone for awhile" ;; powerdown) MSG="$UPS, $CHMSG - Going powerdown" ;; commbad) /usr/bin/logger -i -t upssched-cmd "Communcation with UPS is lost" ;; *) /usr/bin/logger -i -t upssched-cmd "Unkown arg: \"$1\", $CHMSG" exit 1 ;; esac /usr/bin/logger -i -t upssched-cmd $MSG /usr/local/pkg/nut/nut_email.php $MSG exit 0
Make this file executable :
chmod +x /root/upssched-cmd.sh
and be careful for the file encoding. (Unix LF UTF-8, not some Windows format)
It's this file that takes care of the mail sending when power events happen.
Do not use this option :
as it hard codes a mail transmission, and blast away other possible settings.
=> Never ask a stupid GUI to do something that you can do yourself better ;)
The thing is : there can only be ONE CMDSCRIPT in /usr/local/etc/nut/upssched.conf.Check the GUI 'mail me' option and that places the CMDSCRIPT. I wanted to have some more control of the process.
As you ca see, I use the NUT mail php script to mail : "/usr/local/pkg/nut/nut_email.php $MSG".I'm using the settings and files as shown. I'm not saying they are perfect. I just want the systems to go down as soon as a power loss event arrives.
Btw : and yes, NUT is quiet big, and you can make it as complex as you want.
Testing is important, and you have to test a lot. No testing means : you have an UPS and you still have a no controlled power loss which might translate in data loss. -

@Gertjan
Thank you, your suggestions have been very valuable.
I haven't tested them all yet because I had to deal with another problem at the office, but it will be the first thing I do tomorrow (Monday).
But now WinNUT-Client has immediately detected the status of the UPS.In the meantime, I want to ask you a few other things, hoping not abusing your courtesy.
- I also read in other comments that the name is "ups"; is it perhaps binding? I named mine as the model of UPS (Back-UPS_BX2200MI)
- I haven't seen how to run a script from WinNUT-Client yet. Do you have a suggestion about it?
- In your opinion, an ESXi host server (Free) and a Proxmox server is better to shut down by a command executed from WinNUT-Client, or directly from the script on pfSense?
-
@darkcorner said in NUT package:

People often use the name "ups" because some NUT installations, particularly those on NAS, are hardcoded to use that name.
-
But I didn't understand how to get pfSense and the servers to turn on after they shut down.
There is a delay. If the power returns before the shutdown has started, everything will stay on. And that's OK.
But two cases can arise, especially in the evening when nobody is there.- The power is back, but the shutdown has already started or maybe pfsense and the servers are already off.
- Power has returned, but the battery is now dead and the UPS is off.
Sure, one person can turn everything back on, but what if you want the machines to turn themselves back on?
-
@darkcorner
2. is not an issue. this can be solved through the bios setting.
i.e. acpi settings to power on upon restoration of power.it is 1. that is a problem. i.e. the system shutdown because the timer has determined to shutdown, but the battery hasn't expired before the restoration of power. now there is no way to wake the system up, unless you can use a WakeOn LAN function. But so far, i haven't worked out how to make the switch cause a wake-on situation for the pfsense box
