Re: How to Monitor servers in multiple Subnets?

I'd be curious to see what a tcpdump on the nagios server and on the destination server show. On the nagios side you can run:
Assuming the other host is a linux variant and has tcpdump installed you can run this at the same time:
Run both of these while you run the snmpwalk and check commands.
Code: Select all
yum -y install tcpdump
tcpdump -i any host DESTINATION_IP and port 161
Code: Select all
tcpdump -i any host NAGIOS_IP and port 161
