How do I connect the UPS to pfsense? If it is possible ?

elvisimprsntr

Install NUT via package manager
Connect USB comm cable between UPS and pfSense
Run the following via SSH CLI

nut-scanner

Example output

Scanning USB bus.
No start IP, skipping SNMP
Scanning XML/HTTP bus.

Log into pfSense GUI and head to Services->UPS->Settings.

Example config

UPS Type: Local USB
UPS Name: upsmon
Enable notifications: Y
Driver: usbhid

Additional configuration lines for upsd.users
[upsmon]
 password = upsmon
 upsmon slave

Other clients (TrueNAS, etc.) plugged into the same UPS can install NUT and connect to pfSense as a UPS slave.

i installed snmp card model dt801 netagent minigo
the ups is connected to the network and has ip

can i use this ? or only with usb ?

JonathanLee

@firefox yes I agree use the nut package it is really good

I do not recall Nut having the ability to interface via IP but agree this would be a great option..

APCUSBD might have some ability to do what you want but someone else would have to chime in..

Yes, I think. You can try

UPS Type: Remote SNMP
Remote IP address or hostname: {IP address}

You can check using the following command to see what it thinks the best driver is

nut-scanner -s {IP address]

firefox

@elvisimprsntr
it is not work

nut-scanner -s 192.168.1.61

give this

@firefox

Use USB connection method then.

dennypage

@firefox Can you do an snmpwalk of the device?

firefox

@dennypage
how do i do that ?

dennypage

@firefox Here are man pages for snmpwalk and snmpcmd.

Examples:

snmpwalk -v 1 -c public IPADDR
snmpwalk -v 2c -c public IPADDR
snmpwalk -v 3 AUTH/PRIV IPADDR

See the man page for appropriate AUTH/PRIV options.

firefox

@dennypage

[2.7.2-RELEASE][admin@pfSense.home]/root: snmpwalk -v 1 -c public IPADDR

I copied and pasted the commands into the shell.
Still not working

IPADDR

Change that for the real IP address the UPS uses.
Like example : 192.168.10.10

firefox

@Gertjan
This is the first thing I did
I got this answer
So I thought maybe I was wrong and should write it like it is

[2.7.2-RELEASE][admin@pfSense.home]/root: snmpwalk -v 1 -c public 192.168.1.61
Timeout: No Response from 192.168.1.61
[2.7.2-RELEASE][admin@pfSense.home]/root: snmpwalk -v 2c -c public 192.168.1.61
Timeout: No Response from 192.168.1.61
[2.7.2-RELEASE][admin@pfSense.home]/root: snmpwalk -v 3 AUTH/PRIV 192.168.1.61

Ok, time to show the technical doc. The commercial one won't help us here.

You're not going to get by without reading the documentation. The commands I posted were examples, not the literal commands you need to use.

Specifically:

IPADDR was intended as the IP address of the device. You are expected to change this to the real value.
public was an example security group for version 1/2c protocols. public is a commonly used default, but the first recommendation of everyone is to change it. You need to know the actual group in use on the device. Some devices even generate a random value for the group installation. If you have the wrong group, the device simply will not respond at all.
AUTH/PRIV was intended to be replaced with the appropriate authentication and privacy options if the device when using version 3 protocol. There is no generic guidance for this. You have to read the device manual to know and/or set the actual options the device expects. If you have the wrong options, the device will not respond.

If you want to use SNMP, you are going go need to know a good deal more about it, and the device itself. Read the UPS and SNMP card documentation, and then read the SNMP man pages I referenced. This will take time. If you don't want to invest that time, you'll have to try USB.

firefox

@dennypage

I went into the graphical interface of the UPS and changed something there according to what you said.
Now the result is different.

I can't post the result here, it's too long. {The system thinks it's spam}

I added the pfsense IP in the first column
and changed the permissions to read write

Use USB connection method then.

Save your sanity. Use USB connection.
Then send the SNMP card back to recoup some of your coins.

dennypage

@firefox I assume that you are aware that you should not have a community named public write enabled.

firefox

@dennypage
This is a home network
How critical is this?

Unless it gives access to people outside the network ??

dennypage

Does it matter?

It's trivial to correct. The public community should always be read-only. Use a randomly generated string for the write community.
