Additional things to do:"
    1. Check if the proxy settings are appropriate for reaching the test
       manager host. Python does not support domain matches starting with ".".

       For Debian and Ubuntu: check /etc/environment.
       For EL: check /etc/profile and/or the files in /etc/profile.d/.

    2. If the system should be doing RAM disk based testing, add the following
       (or something similar, adapted to the system) to /etc/fstab:

         tmpfs /var/tmp/testbox-1000 tmpfs defaults,size=16G 0 0

After making such adjustments, it's the easiest solution to reboot the testbox.

Enjoy!
