I have configured my snmpd.conf file on a redhat machine and started the daemon (without errors). When I try and do a snmpwalk, I get Timeout: No Response from localhost. I look at the log file and I have
Connection from 127.0.0.1
Connection from 127.0.0.1
Connection from 127.0.0.1
Connection from 127.0.0.1
Connection from 127.0.0.1
Connection from 127.0.0.1

This happened whether I created a basic snmpd.conf using the utility or manually configuring the file. On another machine I was able to get system data but then it timed out.

I want to be able to capture performance data for my Opennms server.

Any suggestions?

I believe it might be a firewall issue
