Hey All,

Firstly I'm a newbee to NetXMS.

I'm having issues making the agents work. I have installed the agents on 2 x Windows boxes (64bit version). When I add the Node, it does add the Node by comes up with NIC as unknown and looks like the NetXMS cannot communicate to the agents. From the NetXMS server I can ping the machines with the Agents installed no problem.

What am I missing???

Thanks

Further to my post.

I have worked out it is connecting, just not getting any details.

Here is another server with the same issue I have a agent installed on;

What would cause this to fail? It's almost like the NetXMS server cannot get any details from the agent service?

Hi,

seems that server cannot connect to agent. Try to check agent log (you may need to run agent on higher debug level - 6 should shouw you all communication related messages).

Best regards,

Ok, I think I'm making progress......

Our NetXMS server is in our datacentre and I have found it seems to have no problem with connecting to a agent in the DC. Our offices are remote to the DC and connected via a VPN. When I pole a machine in my offices the log shows the following error;

19-Oct-2017 07:40:36.117] [INFO ] NetXMS Agent started
[19-Oct-2017 07:42:35.820] [DEBUG] Incoming connection from 14.1.61.XX
[19-Oct-2017 07:42:35.820] [DEBUG] Connection from 14.1.61.XX rejected
[19-Oct-2017 07:43:29.173] [DEBUG] Incoming connection from 14.1.61.XX
[19-Oct-2017 07:43:29.173] [DEBUG] Connection from 14.1.61.XX rejected

So 14.1.61.XX is my offices external IP address. I would say there is some type of IP filtering on the agent that I need to allow the NetXMS server in?

How do I do this?

With thanks (By the way Fantastic product!!!)  - would love to do some training on NetXMS


Update: Fixed by adding MasterServers = 14.1.61.XX in my agent config file :)

Hi,

You need to allow the server to connect to the agent, by adding a line like this:
MasterServers = <IP NetXMS Server is connecting from>
Then restart the agent and check again.
