* Next Step for WebTunnel
* Files · 7e7bebb499a46345b9adf030666698427965e953 · The Tor Project / Anti-censorship / Pluggable Transports / WebTunnel · GitLab
* How to get bridges into rdsys and configure the right args?
* The params can be configured in torrc ServerTransportOptions that will get sent to the PT and readable from goptlib.Binaddr.Args and the PT can use goptlib.SmethoArgs to add them to the file descriptor.
* This will only be readable by bridge authority and rdsys, and not leaked outside.
* Proposal for outreachy
* Submit an Outreachy Intern Project Proposal (December 2022 - March 2023) (#67) · Issues · The Tor Project / Organization · GitLab
* A new format for placeholder addresses in PT bridge lines?
* Make Snowflake recognize FascistFirewall (#40159) · Issues · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab
* 192.0.2.t:n changes to 192.0.2.(16(n−1)+t):80
* t = transport, n = incrementing counter per transport
* Would permit the port number to be one that is always permitted by FascistFirewall, working around Meek and ReachableAddresses (#19487) · Issues · The Tor Project / Core / Tor · GitLab in tor.
== Actions ==
== Interesting links ==
== Reading group ==
* We will discuss "An Empirical Analysis of Plugin-Based Tor Traffic over SSH Tunnel" on Sept 8
* An Empirical Analysis of Plugin-Based Tor Traffic over SSH Tunnel | IEEE Conference Publication | IEEE Xplore
* 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?

Itchy Onion: 2022-09-08
Last week:
- RACE 2.2.x
- Review !98 (Use Pion's Setting Engine to reduce Multicast DNS noise (!98) · Merge requests · The Tor Project / Anti-censorship / Pluggable Transports / Snowflake · GitLab)
This week:
- RACE 2.2.x (made some progres there; I noticed that snowflake doesn't fail the automated deployment tests on its own, but fails when the tests are run as a larger CI test suite. I suspect this is also because of unclosed connection, which is a known issue. This would also explain why I have a difficult time reproducing the error and the lack of error messages, but not why the issue started happening with 2.2.x)
