CentOS - Mar 2011 - Failed to start new browser session: Error while launching browser on session null

Hope this email finds you well.

I need your advice with something if you can help out.

I have an RC serer (selenium rc) which is running on a centos 5.2 and another on
a 5.4 machine.
if i run it through X server, in other words if i run the server while connected
to VNC.
it works fine.
but if i run it through ssh, it will start normally though upon test execution
it will fail with the following error:


11:05:01.571 INFO - Preparing Firefox profile...
Error: no display specified
11:05:21.818 ERROR - Failed to start new browser session, shutdown browser and
clear all session data
java.lang.RuntimeException: Timed out waiting for profile to be created!
     
11:05:21.833 INFO - Got result: Failed to start new browser session: Error while
launching browser on session null


any idea how i can solve this?

Thanks,

--Roland

try ssh -X or ssh -Y .
man ssh and man ssh_config (search for "forward")

Like the error says, you need to specify the display.  I.e., on the
remote machine you must set the environmental variable "DISPLAY"...
something like

(export DISPLAY=192.168.1.42:0.0 & firefox)

Though this may work, this may well reveal another, different error, one
having to do generally with permissions.  But we'll take them one at a time.

hth.
