I have installed RHQ 3.0.0.B03

I am using it to monitor local machines and remote machines which are behind a firewall...

The problem is I connect to the remote machines using ssh tunnell

The agent connects ok and then tries to download the plugins...but it is trying to connect to the rhq server based on its (actual) ip address rather than the hostname

It cannot access the actual ip address because of a firewall, but it can access port 7080 by hostname through the tunnell and connect that way.

How do I set the servlet url to hostname instead of ip address or stop it failing over to the ip address

See log excerpt below....agent successfully connects on hostname,

but then fails over to the ip address
