The second `INIT_SEED` should be `RESP_SEED`.George KadianakisGeorge Kadianakishttps://gitlab.torproject.org/legacy/trac/-/issues/11489obfsclient integration for orbot2014-04-24T13:42:31ZYawning Angelobfsclient integration for orbotIn order to support more than obfs2, orbot should switch to using obfsclient from obfsproxy.

To be done:
* obfsproxy is still build and included as an asset.
* The obfsclient binary built with debugging information is gigantic, stripping after build is recommended.
* UI work for pluggable transport protocol selection.

It'd be really, really good to have pluggable transports a known and documented feature of TBB 3.0 once it's out of beta, because many users are going to need them.

Today, however, I got my private obfs2 bridge probed just milliseconds after my own connection from China. I got hit by two random Chinese addresses as we already know it from the Tor probing. After the probing, my obfs2 connection timed out and the SYN/ACK segments from the bridge were dropped when trying to establish a new connection. I could reproduce all of this several times.
I haven't tested obfs3 yet and I suppose we can skip the old looking-for-the-fingerprint game. Depending on what protocols they are trying to detect, they might have to probe several times since it's not clear what's behind all that entropy. It might be obfs2, obfs3 or VPN PSK and perhaps even more protocols.Philipp Winterphw@torproject.orgPhilipp Winterphw@torproject.orghttps://gitlab.torproject.org/legacy/trac/-/issues/8173Amazon Cloud instructions for port forwarding2020-06-13T17:20:50ZcypherpunksAmazon Cloud instructions for port forwardingThe caption in picture six should also mention port 52176:
