Hey everyone! Here are our meeting logs: http://meetbot.debian.net/tor-meeting/2021/tor-meeting.2021-09-09-16.00.html and our meeting pad: Anti-censorship work meeting pad -------------------------------- Next meeting: Thursday September 9th 16:00 UTC Weekly meetings, every Thursday at 16:00 UTC, in #tor-meeting at OFTC (channel is logged while meetings are in progress) == Goal of this meeting == Weekly checkin about the status of anti-censorship work at Tor. Coordinate collaboration between people/teams on anti-censorship at Tor. == Announcements == Job opening on the anti-censorship team: https://www.torproject.org/about/jobs/software-developer-anticensorship-2/ \o/ == Discussion == - what's going wrong with these connection failures? - https://bugs.torproject.org/tpo/anti-censorship/pluggable-transports/snowfla... - could just be getting unlucky with non-working proxies, and reaching the SOCKS timeout - will ask them to enable the snowflake-client log - is it ok to change the IP address of a bridge periodically (e.g. once per year)? - https://lists.torproject.org/pipermail/tor-relays/2021-August/019788.html - it's ok, bridgedb will start distributing the new IP address (existing users of the bridge lose access) - bridges are assigned to pools based on a hash of the fingerprint; is it possible for a bridge to fall into the manual, human-distributed pool that way? or are all those bridges hand-selected? == Actions == == Interesting links == Blocking of DNS/DoH/DoT servers of Google/Cloudflare/OpenDNS in Russia, begins today(?) https://github.com/net4people/bbs/issues/81 https://ntc.party/t/doh-dns-google/1225 Disruptions of BitTorrent and WireGuard in Russia last week https://github.com/net4people/bbs/issues/76#issuecomment-915544316 https://github.com/net4people/bbs/issues/83 https://ntc.party/t/an-open-encyclopedia-of-internet-censorship-persian/1223 == Reading group == We will discuss "BlindTLS: Circumventing TLS-based HTTPS censorship" on 2021-09-23 https://dl.acm.org/doi/10.1145/3473604.3474564 Questions to ask and goals to have: What aspects of the paper are questionable?
