UPSMON independent shutdown.

You can install bash if you really need to.
What part fails id you use sh?

but the bigger issue is, this is a bash script

Although bash is probably a more powerful shell, I guess the script's syntax could be re written in sh syntax.

@Gertjan is that something you could help with pls? i would have no clue as i am not familiar with either

Gertjan

First things first : extreme, but you won't regret it : do not use the build in GUI file editor.
Use a console or better : ssh access. You'll be having full control, you can see file permissions, attributes etc.

The GUI file editor is only used by experts ... and they probably use when they want to fly blind.

@gwaitsi said in UPSMON independent shutdown.:

but the bigger issue is, this is a bash script (which is not installed)

I'm experimenting right now with this upssched-cmd ....
See here https://dan.langille.org/2020/09/07/monitoring-your-ups-using-nut-on-freebsd/ for guidelines and the entire https://networkupstools.org/ .....

Be careful : you've seen that pfSense (re) creates /usr/local/etc/nut/upsmon.conf and other .conf files in that dircetory. Use the GUI NUT pages to add your own lines to these files.

@Gertjan hi, I created my files a linux text editor. I copied and pasted them into the filer package.

/usr/local/etc/nut/upssched.conf 	0644 	UPS Shutdown Scheduler Configuration 	
	 
/usr/local/bin/upssched-cmd 	0755 	UPS Shutdown Scheduler Command Script

The extra upsmon script commands were added to the advanced tab.
the log clearly shows the script is being triggered, but just i don't know what i am doing with the scripts to be able to convert it.

@gwaitsi said in UPSMON independent shutdown.:

Again : use ssh directly, you'll feel @home right away.

I advise you to execute this on pfSEnse :

pkg install nano

I guess you know who 'nano' is ;)

I don't know what you mean with

/usr/local/etc/nut/upssched.conf 	0644 	UPS Shutdown Scheduler Configuration 	
	 
/usr/local/bin/upssched-cmd 	0755 	UPS Shutdown Scheduler Command Script

Btw : I have a Back-UPS 700 APC ups, hooked up using a USB cable.

These are my settings :

upsmon.conf : the strict minimum, as the other settings in upsmon.conf will be set to default. see upsmon.conf.example for the values.

The upsd.conf contains the LAN IPv4 and IPv6, as my pfSense NUT us a UPS master - I have a disk station NAS being the NUT slave.

The upsd.users section shows the login details of the NAS.

My /usr/local/etc/nut/upssched.conf file :

-r-xr-xr-x   1 root  wheel    649 Nov 12 15:36 upssched-cmd

CMDSCRIPT /usr/local/etc/nut/upssched-cmd

AT COMMBAD  * START-TIMER commbad 30
AT COMMOK  * CANCEL-TIMER commbad commok
AT NOCOMM * EXECUTE commbad
AT FSD * EXECUTE powerdown
AT SHUTDOWN * EXECUTE powerdown

Take note of the location of the "CMDSCRIPT " file : /usr/local/etc/nut/upssched-cmd file

See also : "onbatt 20" which means that I receive notifications by mail etc after "20 sec" - not the default 300 seconds.

Here is /usr/local/etc/nut/upssched-cmd file :

#! /bin/sh

UPS="ups"
STATUS=$( upsc $UPS ups.status )
CHARGE=$( upsc $UPS battery.charge )
CHMSG="[$STATUS]:$CHARGE%"

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"
	;;

    logger -i -t upssched-cmd "Bad arg: \"$1\", $CHMSG"
    exit 1
    ;;
esac
logger -i -t upssched-cmd $MSG

This is logged when I pull the plug :

Read from bottom to top.
I received the mails.

i will give it a shot.

fyi - If you use nano to create upssched.conf and upssched-cmd the files will be lost if you have to re-install.

If you install the "Filer" package, you can create those files under the Diagnostics menu and the contents will be saved to config.xml, so you can transfer the settings to a new install.

stephenw10

You can also use the included Easy Editor ee which provides much the same functionality as nano.

@gwaitsi said in UPSMON independent shutdown.:

If you install the "Filer" package,

True ! In fact, discovered yesterday that "Filer" wasn't the build-in GUI editor ...
I use the Notes package myself : for every change I made that can't be done with the GUI, thus stored for eternity, I take notes.
This forces me to re read the documentation if I want to implement changes. Not only pfSense changes over time ;)

@stephenw10 said in UPSMON independent shutdown.:

I know. nano is just a personal preference, as it exists on all my pfSenses, and linux based servers. I'm trying to limit my have-to-know keyboard short-cut list to a minimum as I'm stilling suffering from the vi syndrome.

4o4rh

So it is looking good so far, lost comms are from shutting down the service on truenas. forced shutdown from lost comms works.

Still need to test how long the battery on the dumb ups will last. It should last much longer than the apc ups which gives me about an hour for power to be restored.

i will have on rare occasions a use case when the power is gone for more than an hour and pfsense shuts down, but the battery doesn't die before power is restored. in such a use case, pfsense will need to be manually re-started.

Anyone got any ideas?

What is is the question ?
How to manually restart ?

For the "AT ... timer commands", see the upssched.conf file.

@Gertjan the ups on the pfsense (Qotom J1900) is like a power adapter with a battery e.g. it is dumb. pfsense is triggered via truenas server which has a apc ups connected to it.

If the power comes back on before the pfsense powers down, all is good. it will run on battery and continue.

If the pfsense shutdowns, but the ups battery doesn't deplete, the J1900 will never see a loss of power and therefore wont know to turn back on, so has to be manually started.

Looking for ideas on how i could solve this scenario.

Gertjan

@gwaitsi said in UPSMON independent shutdown.:

J1900

If the J1900 supports WOL .....

stephenw10

Yeah, WoL is probably the only option there without some additional hardware.

Steve

4o4rh

sounds like a good idea fellas, just need to figure out how to do that now ;-)

Gertjan

If your J-thing is a typical PC device, check the BIOS.
WOL is nothing more a an always-on chip (activated as soon as there is some power) and simulates a press-power-on-the-button as soon as it sees it's own MAC 3 times in a packet load over the/a Ethernet interface, typically the LAN interface.

If not : you found yourself yet another Rasberry/PI project ;)

4o4rh

does anyone know how to set a netgear switch (GS108Tv3) up to provide the magic packet

Gertjan

@gwaitsi said in UPSMON independent shutdown.:

WOL for GS108Tv3

=> They should know it : https://community.netgear.com/t5/Smart-Plus-and-Smart-Pro-Managed/GS108Tv3-how-to-wake-up-pfsense-router/m-p/2007829
If you need a fast answer : look in the Netgear's GUI or go for the manual.

Bad start : Google doesn't know about it, so chances are great the router doesn't have WOL capabilities.

4o4rh

@Gertjan couldn't find anything in the gui. there is a section on green ethernet, but it is not clear to me whether that causes broadcast magic packets. (i thought the specific mac address had to be used)

Gertjan

You can WOL with pfSense.
pfSense, as your switch, should be 'always' on.
