Hello,

We've been struggling to get the monitor working with the latest version of ngrinder (3.3.1) and were wondering if you had any ideas.

It looks like the controller cannot communicate with the monitor's JMX bean over RMI, which is something I've confirmed by trying to connect using jmc. We've been all over the network settings and all ports are open, nothing is locked down and I've even tried it on an entirely separate network and on an internal network using VMWare and still it doesn't work.

I can see that the initial connection does make it through as I turned on logging within the monitor and I get this line output:

FINER: RMI TCP Connection(3)-10.43.196.192: [10.43.196.192: sun.rmi.registry.RegistryImpl[0:0:0, 0]: java.rmi.Remote lookup(java.lang.String)]

10.43.196.192 is the IP address of the machine making the request, so it's definitely getting through, but then nothing happens and the request just hangs.

We've tried this with both Java 7 and Java 6 without any luck. The problem seems to be that it's disappearing into the RMI lookup method but I can't work out why.

Any ideas?

**EDIT** I should add that we have tried this on 3.3 (the latest release version) and then moved onto trying it with 3.3.1
