@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.

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

@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
snmpwalk: Unknown host (AUTH/PRIV) (No such file or directory)

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.

@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 ??

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.

Update
I did a factory reset to the snmp card
When I received the snmp card
it still had the settings from the previous location
After the reset it works
And I see the status of the UPS in pfsense

@firefox Glad you got it working
