Hi Team,

I followed the instructions for

I am using Centos7 for my servers which led me to:

1/3 servers worked, but I don't know what I'm doing wrong.

This is the error I get when I am trying to start the snmpd service:

Easiest would be to go with the default configuration (install and start snmpdconf to generate one) and see if that works properly. Nothing wrong with the NIC configuration from what I can tell.

Hi Stephan,

I've tried to uninstall snmpd and snmp and re-installed it. Defaulted the snmpd.conf file but still unable to start the service. Do you have any other hints / tools that may be potential culprits? I've tried to set it up on another CentOS server (on AWS) and I am getting the same error on a fresh server.

Thanks,

Kind Regards,

Daniel

Then it's more likely to be a case for the centOS forums :/ This is usually working out of the box.
