A couple of things to check for this is do you have SNMP installed and enabled through the firewall for the localhost?
In your example, you are not specifying the SNMP version, most newer systems are running SNMP version 2 and if the localhost is running version 2, try running the command as below.

Code: Select all

./check_snmp -H localhost -C public -o .1.3.6.1.2.1.25.2.2 -P 2c

Let us know if this works or not.
