NetXMS Support Forum

Is it possible to run multiple NetMXS consoles to the same database?  My attempts to do so comes up with the connection error message "Unable to connect: Communication failure".  This error is displayed after about 3 minutes (after Connecting to server).
Data input - Server address, User name and User password.

My net result is to see the graphs remotely on other terminals/computers.

Thanks.  Tony

Hi!

Yes, it's possible. Communication failure message means that console cannot connect to the server. If you can connect locally (from console installed on server machine), possible reasons could be: firewall on server machine; firewall in between server and client; misspelled server name or IP address.

Victor thanks for the reply and yes you are correct it is a Firewall issue.  I thought I had tried to disable the fireawall before posting but I guess I messed up in doing so.  Now with the server's firewall disabled all network computers running Console can connect.  I tried to add a rule to the firewall to allow for firewall protection and allow for Console server access but am having isses.  The following rules are currently in place
InBound Rule
- MySQL - All Programs - Local Port 3306 - Remote all ports
- NetXMS Console - Program NXCon.exe - Protocol TCP, Local and Remote all ports
- NetXMS Console - Program NXCon.exe - Protocol UDP, Local and Remote all ports
Outbound Rule
- None (for NetXMS)

Can you guide me into what I should do to allow for console access with the firewall engaged.

Thanks.  Tony M.

OBTW - Running Wins Server 2008R2.

Console uses port 4701 to connect to server, so on client side you should allow remote port 4701 for nxcon.exe (and Java console), and on server side you should allow local port 4701 for process netxmsd.exe.

Best regards,
Victor

Victor you are the person of the hour. 

The key that opened the firewall door was adding a local port (4701) for netxmsd.exe . 

Thank you so much.
