<![CDATA[Communication to agent stops working]]>I have a problem with NetXMS communicating with the agent but before I jump right into the issue I will provide background information.

I originally had the NetXMS server in install on a report server with SQL 2005 installed using NetXMS version 2.19, everything was working fine (only one NIC connected). I was then asked to move it to another workstation again everything was working fine. I have now been asked to move it back to the original report server. Everything is not fine anymore.

I made sure that I preformed a fresh install (previously uninstalled NetXMS) uninstalled the agent and deleted NetXMS folder. Detached database in SQL 2005; deleted user account and removed the DB and log files from the SQL data folder.

Installed version 2.21 install went without a hitch. Upgraded agents to version 2.21, open NetXMS console and started receiving node objects however they all showed agent inactive. In the setup I used localhost for the server and pointed the agents to IP of server (172.28.7.29) at this point I had two LAN connection on this server, I disable to 2nd LAN (172.28.7.196) and restarted server which failed to restart. When I checked the event logs there was a log that stated the "database was locked by 172.28.7.196" after searching this forum I found the command to unlock the DB. This allowed the service to restart in which case when I polled the status of the node I got the message that the Agent was running.

After several uninstalls and reinstalls and I have since upgraded to version 2.22 Console and agents I have determined my issue but not sure how to fix it.

When installing NetXMS with one NIC connected (172.28.7.29) everything works fine but as soon as I reconnect the 2nd NIC NetXMS can no longer communicate with the agents.

I need both NICs connected is there anyway to fix this? ???

Also when I created a management pack and then tried to import it, it could not because it did not save the pack with the .nxmp extension, so I had to recreate my events and templates each time I reinstalled the program. Can this be fixed? ???

Thanks in advance!!

Also, I will set the agent to use the server name instead of the IP. 😄

If you have two (or more) IP addresses on your management server, they all should be listed in agents' MasterServers parameter. In your case, all agents should have in nxagentd.conf

MasterServers = 172.28.7.29, 172.28.7.196

Best regards,
Victor
