Feature #5937
obfsproxy
0%
Description
The Obfsproxy project exists to achieve the benefits of Tor’s bridges together with traffic obfuscation.
Use cases
Censorship circumvention
Since bridges are easily detected and blocked in some areas (in particular China, but also places where wholesale SSL blocking is used), something like obfsproxy is needed in Tails.
Hiding Tor usage
In situations where both reliability and obfuscation are required despite an adversary having control of the user’s local network traffic obfuscation must also be employed. This traffic obfuscation is imperative where the user’s welfare or liberty my be jeopardised by her use of Tor.
Implementation
The branch feature/obfsproxy
currently adds rudimentary support for obfsproxy. It’s possible to just add a bridge like obfs2 $IP:$PORT
through Vidalia’s settings and it works (also works with bridge-mode so that even in its current implementation (which doesn’t use DisableNetwork
), Tails prevents Tor from talking to the network, and makes Vidalia prompt the user for bridges, obfs2
or not).
Merged in Tails 0.15.
