Javatest provides an HTTP Server to use to monitor tests results among other things. It uses the machines IP address as a URL to be entered in a browser. In Windows and Solaris this works properly. However, in Ubuntu 10.04 it uses the local IP address, 127.0.0.0. As a result the only way to use this feature is on that local machine.

You can try this on the following Ubuntu 10.04 machines
javathing, javathing2, j2me-tck-2
