snmpwalk oddity
Posted: Wed Aug 26, 2015 1:22 pm
I am trying to figure out why some servers are have service checks issues and I came across a weird problem.
We have an XI server with 3 mod gearman workers. When I perform snmpwalk from the XI box, it is timing out (which causes issue when trying to run the network wizard). Now moving over to the mod gearman workers and they are able to do full snmpwalk on the server. There is no firewall and they are on the same subnet. The snmp configuration looks to be fine and allows for all IPs involved. Really not sure why it just won't work from the XI server.

.100 is the XI box and the others are the mod gearman boxes.
