There is a currently unmerged branch of mine that add some features to the HTTP Host test. Specifically it tests for some HTTP Proxy bypassing techniques (prepending a \n to the GET method and postfixing the Host header field with a \t), it checks if filtering is happening also on subdomains, if it's done based on fuzzy matching. You can find it here: https://github.com/TheTorProject/ooni-probe/pull/51 (this is the branch: https://github.com/hellais/ooni-probe/tree/experimental-tests). The tests that are most relevant to your endeavor are: * nettests/manipulation/http_invalid_request_line.py (for example bluecoat transparent HTTP proxies are know to crash with some, but not all of these requests) * nettests/manipulation/http_host.py, with the added patches in my experimental-tests branch it will also attempt some filter bypassing techniques that can be useful to understand what the device in question is. * nettests/manipulation/http_header_field_manipulation.py, when pointing this towards a oonib test helper you will understand if the device in question is adding extra HTTP Headers or performing some other HTTP header mangling. > > Also, I'm testing on a debian (6.0) VM running in a parallels 8 on OS X. > Ooni successfully runs tests once , and then requires a debian reboot in > order to run again (especially http_host, it was less repeatable with > others).

What exactly is it that leads you to need to reboot? Are you seeing some errors after the first run? What version of ooniprobe are you running?
