Hello All,

I am running Centos 6.3 and attempting to use snmp v3 to query OID's on this server. Running Paessler's(https://kb.paessler.com) snmp tester 5.1.3 I get a no response from host. I have made sure that my iptables do not have any odd firewall settings. I can verify that snmpd is listening on port 161. I have also made sure that SELinux is fully disabled. I am able to install this on Centos 7.1 without any issue. I have done a tail on the messages in var/log/messages and can see incoming traffic for snmpd i.e emc(https://goo.gl/S92kpR). I am stumped and have no idea why this will work on one version of this OS but not another. I wonder if anyone has any suggestions.

Thank you

Dear qnanasekar,

Thank you very much for your contact and please excuse the long delay on this.

Unfortunately, we are unable to further analyse the issue if the SNMP Tester in not able to fetch any valid SNMP information from the targeted device.
Usually, the check for the system's uptime should be a good indicator if the SNMP Tester is able to query these (mostly standardized) information. As a shot in the dark you might consider to check out this article for further diagnosis.

Best regards,
Sebastian
