Most of these tools have GUIs that will not go away. This is especially true for tools that run on Windows. These products literally do not run without the GUI. It is better to deal with a command line and ASCII log files.
I often need to run tests on the other side of one or more firewalls and get the results. Don’t even try to run some Windows GUI-based application remotely through a firewall. You’ll waste your time. Even if it used X, it wouldn’t work because firewalls by nature will say no to most protocols and ports, including X.
