Over the past months, we have been working on the ScrambleSuit pluggable transport protocol [1]. The code has now reached some maturity and it's time to test it! I set up a dedicated bridge and compiled a set of installation instructions listed below. You get bonus points if you test the bridge from within China since ScrambleSuit should resist the GFW's active probing attacks.
There are probably still some hidden bugs. If you stumble upon something unexpected, please file a trac ticket or reply to this email. So here are the installation instructions. I tested it on Debian wheezy but it should work just fine on other Linux distributions. 1. Two additional Python packages are necessary: gmpy and yaml. Debian has them under the names "python-gmpy" and "python-yaml". 2. Clone and compile the current Tor-git (or use a version of your choice as long as it is >= v0.2.5.0-alpha-dev): $ git clone https://git.torproject.org/tor.git 3. Clone the current version of pyptlib (or use a version of your choice as long as it is >= 0.0.5): $ git clone https://git.torproject.org/pluggable-transports/pyptlib.git 4. Clone a modified version of obfsproxy which contains the scramblesuit branch: $ git clone -b scramblesuit https://git.torproject.org/user/phw/obfsproxy.git $ cd obfsproxy/ $ git submodule init $ git submodule update 5. You can use the following torrc: ------ DataDirectory /tmp/scramblesuit-torclient SOCKSPort auto UseBridges 1 Bridge scramblesuit 193.10.227.195:9002 password=5TYVADJINHBB67PJSBPSWVR5IO742PVO ClientTransportPlugin scramblesuit exec <path-to-obfsproxy-dir>/bin/obfsproxy \ --log-min-severity=debug \ --log-file=scramblesuit-client.log \ managed ------ 6. Now start Tor over ScrambleSuit by executing: $ PYTHONPATH=<path-to-obfsproxy-dir>:<path-to-pyptlib-dir> \ <path-to-tor-dir>/src/or/tor -f <path-to-torrc> [1] http://www.cs.kau.se/philwint/scramblesuit Cheers, Philipp -- tor-talk mailing list - tor-talk@lists.torproject.org To unsusbscribe or change other settings go to https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-talk
