I need someone's bridge experience. I had an HD crash and lost one of my Tor bridges. So, I'm rebuilding on a leased VPS. First I tried with Debian 8 and then with ubuntu 16.04 when Debian didn't work. With both operating systems I get a warning message when I start Tor. Tor is the latest version as is obfs4proxy: Sep 04 13:39:41.641 [warn] Strange ServerTransportPlugin type 'obfs4' Sep 04 13:39:41.641 [warn] Failed to parse/validate config: Invalid server transport line. See logs for details. There are no log entries. Apparently Tor starts without the proxy. I have configured torrc as follows: ServerTransportPlugin obfs3 obfs4 exec /usr/bin/obfs4proxy ExtORPort auto /usr/bin/ does contain the obfs4proxy file. Does anyone know my problem? Is there a 'tell-all' explanation of obfs4proxy? Thanks, Arisbe
