Remote Control Broker

jkj1962 · July 30, 2018, 8:25pm

So, the Remote Control Server install/config went fine. It’s the Broker that kicking my butt. As far as I can tell, I’ve got it configured properly. I’m doing this on a test server, so there’s no firewall involved. The idea is if I get this working I migrate the settings to the final server in the DMZ. When I choose “Start Broker Session”, it get to the point where the Controller opens, then get an error that it won’t connect. I’ve enabled the trace for the controller, and all seems fine until:

I’m using a non-standard port because I’ll be piggybacking on an existing DMZ server that is using 80/443 already. Again, there’s no firewall in between any of the controller/server/broker. Obviously I’m missing something somewhere.

Hi jkj1962,

Sorry for the late answer.
The error that you got is a “Connection refused”.
Are you sure that the broker is running and listening on port 8880 ?

You can use the following commands to check that:

Windows: netstat -abo | findstr 8880
-Linux: lsof -Pan -i | grep :8880

If the port is not reported you have to check the broker configuration and ensure that the lines DefaultPortToListen and xxx.ConnectionType = Inbound are not commented.
You should have something like this:

...
DefaultPortToListen = 8181
...
myInbound.ConnectionType = Inbound
...
myInbound.AllowEndpoints = yes
...

I appreciate the response. I had put this aside for other things.

I do have those settings, but there is nothing listening on port 8880. I suspect there might be an issue with the certificate, and the broker service just isn’t starting up properly because of it. I’m going to have to put in a PMR I guess.
