On a normal system, the tests pass fine, and it would be a bug if they didn't. Did you look at the `tor_ersatz_socketpair()` code at all? It should be obvious why this is failing on Tails. > Is there a suggested workaround? Or perhaps is it possible to easily > ignore this one test? Suggested workaround(s): * Don't use Tails, the tests are written under the assumption that they are running on a normal system that doesn't have a facist firewall preventing connections to things listening on the loop back interface. * Patch the test code to disable that test. * Maybe use torsocks with "AllowOutboundLocalhost", if the version included in Tails supports the option (I'd hope so, I added support for that feature to torsocks specifically for them). Other tests may or may not fail if you chose to go down this path. Regards, -- Yawning Angel
