Getting the pfSense version with SNMP

Benjamin B

Hello,

I am working with snmp on pfSense and I can't find the oid where the pfSense version is given.

I only have the freeBSD version on '1.3.6.1.2.1.1.1.0'

I could use some help.

Thank you,
Benjamin

Anyone using SNMP can help me?

Noop.
But Google told me you can start here : https://forum.netgate.com/topic/55910/snmp-oids-for-monitoring-pfsense-via-mrtg

I tried a snmpwalk on all oid available after activated all default SNMP Modules (MibII, Netgraph, PF, Host Resources, UCD and REGEX) but nowhere in the result do I have the version of pfSense (which is 2.4.4-RELEASE-p3).

I searched this regex /2.4.4/

Am I missing something or does the pfSense version not given by default?

Is there another SNMP module required to access this data?

You can't find 2.4.4 info, because that version doesn't exist anymore (snmp bug).

The actual version works just fine :

root@DiskStation2:~# snmpwalk -v1 -c public 192.168.1.1 | grep 'pfSense'
SNMPv2-MIB::sysDescr.0 = STRING: pfSense pfsense.brit-hotel-fumel.net 2.4.5-RELEASE-p1 pfSense FreeBSD 11.3-STABLE amd64
SNMPv2-MIB::sysLocation.0 = STRING: pfSense
HOST-RESOURCES-MIB::hrSWRunParameters.426 = STRING: "-q -f /etc/pfSense-devd.conf"

Btw : for "regex" reason, this

snmpwalk -v1 -c public 192.168.1.1 | grep '2.2.5'

will not work. "2.4.5" isn't a literal search string !
