pfSense with SNMP v3 - Interfaces not populating

Hello,

I am running into an issue trying to connect NetWorx (running on MacOS) to my pfSense router using SNMPv3. In the SNMP settings screen on NetWorx, I have selected "authPriv", filled out the Auth password with SHA and the Priv password with AES. When I click the "Test" button, I see the correct details for my router, which I think means everything is configured ok. After clicking "OK", the Router window does not update with a list of interfaces for my router, it just stays blank. Just wondering if this is a bug or if I have something configured wrong?

On pfSense I installed the "net-snmp" package and disabled the default "SNMP Daemon" to get SNMPv3 working. From my Mac, I am able to use "snmpwalk" to get a load of info from pfSense so I think I have the pfSense side configured ok.

Regards,
Scoot

That's odd. Would you be able to dump the ifTable using snmpwalk and post it here, please?

snmpwalk -v3 -l authPriv -u <username> -a <auth_protocol> -A <auth_password> -x <priv_protocol> -X <priv_password> <device_IP> .1.3.6.1.2.1.2.2

Hi Andrew,

Yep, no problem. The output is below. Thanks for taking a look!

One thing I did notice, on the command line, the <auth_protocol> I am using is SHA, while in the NetWorx app, the only options are MD5 or SHA1 so I have been selecting SHA1. I had assumed that either would work (SHA vs. SHA1) because the "test" appeared to work.

Yes, SHA and SHA1 refer to the same algorithm. As confirmed by the connection test, if it returns details, then the credentials are valid. The SNMP walk data you provided also appears correct.

We tested it with net-snmp and believe we've identified the cause. When using SNMPv2c and SNMPv3, we issue a bulk request to retrieve the interface table. For some reason, net-snmp is not handling the default batch size of 50 as expected, but instead of returning the standard SNMP error tooBig (1), it returned a generic error genErr (5).

We have a fallback mechanism in place that dynamically reduces the batch size, but it was only triggered by the tooBig error. We've now updated the implementation to also fall back when encountering a genErr, and this appears to resolve the issue.

Please download the new build and let me know how it works for you.

That worked perfectly

Thanks for the quick fix Andrew!
