SNMP Configuration

Unable to get SNMP queries speaking on NagiosXI 2012R2.5 64-bit trial. Any ideas what the problem might be or where I should look for clues? Thanks.

When you say you are unable to get snmp queries working, are you attempting to query the XI system or a remote device?
How are you attempting to do this, via cli, plugin, or specific wizard?
Have you configured the device you are querying to respond to the specific IP or subnet that you are querying from?

Let's start with those and we can move towards more technical details with more information.

Thanks very much for the response sreinhardt. Trying to get to a specific host (Netscreen 208) on 161 UDP. I know it's configured on the proper management IP to allow SNMP from our trusted network, but I don't seem to be getting a response from the NagiosXI virtual appliance. Ran the scripts that were recommended for SNMP configuration on the Nagios device, but still no joy.

OK great, it sounds like you have a pretty good idea of whats going on, and whats needed to get this setup. Are there any firewalls between the nagios machine and the remote device that might be blocking the port?

Please run the following command and return the output. If you need to feel free to censor ip\hostnames.

Code: Select all

nmap -sU -p 161 [Hostname\IP]

We should have this return with Open, filtered and closed ports will not work 9/10 times as there is something filtering the connection.
