Basically, I have a small network where my OpenNMS installation is located on a CentOS 6.4 machine.
Now I have a server(CentOS also) that I want to monitor but is on the internet, with a public address.
I have installed net-snmp on my target server and configured /etc/snmp/snmpd.conf
When I try to do
snmpwalk -v 2c -c public localhost
on my target system, it returns the expected output.
snmpwalk -v 2c -c public c******2.com
on my OpenNMS server querying against my target server returns a
Timeout: No Response from c******2.com
I tried turning debug on (snmpwalk -v 2c -c public c******2.com -d) and I got this output:
Sending 42 bytes to UDP: [*.*.*.*]:161->[0.0.0.0]
I wonder what could be the problem?
This is my config inside snmpd.conf
