== Discussion ==

 \* Snowflake in Turkmenistan: https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/issues/40024
     \* we are providing a different snowflake bridgeline with specific port for stun servers and azure and domain front
     \* the changes seems to work for AGTS \(one ISP\) but not for others, as they block port 3478 and 3479

 \* TorCloak Integration with BridgeDB
     \* We are currently developing a new Tor Pluggable Transport called TorCloak\. TorCloak's basic mechanism is to conceale Tor traffic on the video streams of WebRTC\-based video conferencing services\.
     \*  We are now coming to a stage on our project in which we are discussing solutions to disseminate our bridges\.
     \* Sent a draft of the solution via the mailing list\.
         \* https://lists.torproject.org/pipermail/anti-censorship-team/2022-August/000239.html
     \* Get everyone's opinion and feedback on the solution

* Next Step for WebTunnel

== Reading group ==

 \* We will discuss "An Empirical Analysis of Plugin\-Based Tor Traffic over SSH Tunnel" on Sept 8
     \* https://ieeexplore.ieee.org/document/9020938
     \* PDF available from Sci\-Hub, DOI 10\.1109/MILCOM47813\.2019\.9020938
     \* Questions to ask and goals to have:
         \* What aspects of the paper are questionable?
         \* Are there immediate actions we can take based on this work?
         \* Are there long\-term actions we can take based on this work?
         \* Is there future work that we want to call out in hopes that others will pick it up?
