Nagios Support Forum

Hi,

I need your help since some FW are not responding to SNMP. We setup this community 7cq%O*p3u&7G
but I am not sure if it has the correct nomenclature, I mean, NagiosXi accept any character?

When I run the command Nagios suggest in the server I get this:

Hi,

For the snmpwalk command, please try wrapping your community string in single quotes and test again.

I searched that error and you seem to be hitting the issue in the document below. Please take a backup of the SNMP_Session.pm, and make the recommended changes and then test again.
