by Cecylia Bocovich 07 Sep '21

07 Sep '21

Hi everyone, This is what we've been up to during July and August! Snowflake ========= * Adjusted Snowflake session layer parameters for better performance. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * Added support for an AMP cache rendezvous to Snowflake. It is not being used yet, but is available if needed as an alternative to domain fronting rendezvous. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * Updated the web proxy for new browser requirements. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * Made the Snowflake client accept configuration in the form of SOCKS arguments (in preference to command-line options). This makes it easier to control the configuration in frontends such as Tor Browser's. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * Assign proxies based on their client load https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * Wait pollInterval in snowflake between proxy offers https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… * Improved Snowflake documentation and READMEs https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… BridgeDB ======== * change bridgedb to send obfs4 bridges by default over email https://gitlab.torproject.org/tpo/anti-censorship/bridgedb/-/issues/40019 * Allowed BridgeDB to see the IP address of moat clients https://gitlab.torproject.org/tpo/anti-censorship/bridgedb/-/issues/32276 rdsys ===== * Integrate GetTor into rdsys https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/32 * Add GetTor documentation https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/44 * Run tests in the CI https://gitlab.torproject.org/tpo/anti-censorship/rdsys/-/issues/58 Other ===== * Investigated changes in user metrics in Turkmenistan. https://gitlab.torproject.org/tpo/community/support/-/issues/40030#note_274… * Bridgestrap CollecTor metrics https://gitlab.torproject.org/tpo/anti-censorship/bridgestrap/-/issues/15 * Set up reachability probes for Tor in Turkey https://gitlab.torproject.org/tpo/anti-censorship/censorship-analysis/-/iss…

User Feedback Report - August 2021
by Kulsoom Zahra 03 Sep '21

03 Sep '21

Greetings, everyone! This is a report of the work done by the Community Team in the past month and general user feedback that we've received across our official support channels. Report Period - July 31 upto 31 August, 2021 Tickets resolved in the past month: 165 Here is a list of issues which got the most attention (at least 2 tickets on RT): # Tor Browser Breakdown of number of RT tickets received with respect to operating system: Windows (10,8,7 ...all the way upto Vista) - 24 macOS - 5 Android - 8 GNU/Linux - 2 iOS - 4 (Note: This includes tickets where the user mentioned the operating system or it was evident from the issue they were running into or enclosed screenshots.) 1. 12 RT tickets - Unable to access websites; Login fails. Users also reported issues with payment on sites like eBay, PayPal etc. Regarding websites blocking Tor users, Hackhard GSoC project is tracking the top 500 websites.[1] 2. 5 RT tickets - YouTube not accessible renders the error "Our system have detected unusual traffic from your computer network". We point users to the "Basic Troubleshooting when users can't access any particular website" article (template) on the RT. 3. 5 RT tickets - "Tor Unexpectedly Exited": Failure to launch Tor Browser. We direct users to the "Seven-point basic troubleshooting" article (template) on the RT to help users. 4. 5 RT tickets - Installation Issue (OS - Windows) We ask users to make sure they've downloaded the correct version of TB depending on their Operating System 32-bit or 64-bit. [2] 5. 4 RT tickets - Fake Tor App on Apple Store. Users are being charged after installing a fake Tor Browser app on iOS. We educate users about fake apps and recommend them to solely use the Onion Browser for iOS. 6. 3 RT tickets - Cannot download files on Tor Browser for Android. Regarding this we have a ticket on our GitLab. [3] A workaround for this recurring issue is to make a new Tor connection and relaunch the download. 7. 3 RT tickets - Error "Proxy Server Refused Connection". We ask users NOT to set TBA as their default browser and point them to the article on the Support Portal. [4] 8. 2 RT tickets - Reporting bad onion sites. The Tor Project doesnot host or control onion sites, we answer users taking help from the article on our Support portal. [5] 9. 1 RT ticket - Error "RSA_get0_d could not be located in the dynamic link library tor.exe" on Windows. We have a GitLab ticket regarding this long standing issue. [6] # Onion Services 1. 9 RT tickets - v2 onion deprecation. Users were confused 'how' to upgrade v2 onions to v3. They were asking for a direct link/button to upgrade. We help users identify v2 and v3 onions, point them to the "v2 onion deprecation" article (template) on the RT and FAQ on the Support Portal. [7] # UI/UX and documentation 1. Google Play Store - In terms of user experience, reviews mostly revolve around- 'Unable to access to YouTube and other sites', 'Tor freezes', 'Can't download anything files/images', 'Tor Browser is slow', 'can't upload files' and 'too many captchas'. However, in terms of reviews we have quite a good number of 4 and 5 star ratings. 2. Tor Stack Exchange - Statistics of what the discussion has been about (6 most active tags): hidden-services- 17 questions anonymity- 12 questions security- 9 questions configuration (questions about configuring Tor software)- 6 questions tor-browser-bundle- 6 questions onion-routing - 4 questions 3. Reddit Discussions have been around: * Tor browser is Looping same exits. * Hidden Service for Minecraft * Can't access YouTube and other sites over Tor * Tor is very slow * VPN and Tor - How does using VPN decrease anonymity? * fdroid version from the guardian project not updated * Onion sites # Anti-censorship 1. 5 RT tickets - Bridges not working Tor logs revealed that it was caused by users editing their torrc file; overriding the exit nodes and 'general SOCKS server failure' errors. We educate users NOT to modify their torrc file and one gets the best security Tor can provide when they leave the route selection up to Tor. Then point them to the FAQ on the Support Portal. [8] 2. 4 RT tickets - Bridge requests We got users requesting help to connect to Tor which have been from Iran, China and other countries. We provided private bridges for them. 3. In the past month, there have been instances of censorship and internet shutdowns in countries like Iran and South Sudan. We're following up on their situation.[9] There has also been a decrease in users connecting directly to Tor from Turkmenistan. We've a ticket open to track the status. [10] If you have any suggestions, questions or want to discuss anything in detail please feel free to reach out to me and/or anyone from the Community Team!

Monthly status report for irl
by Iain R. Learmonth 01 Sep '21

01 Sep '21

Hi All, This is my monthly status report for work complete during August 2021. This will be my last status report for this contract, please direct all queries about metrics tooling going forward to the network health team. I released and deployed updates for CollecTor to archive bridgestrap data. This is currently disabled until the bridgestrap results can be declared stable by the anti-censorship team. If you're interested in following this, see: https://gitlab.torproject.org/tpo/anti-censorship/bridgestrap/-/issues/25 I completed an update to Onionoo that reads in this data from CollecTor and will use the bridgestrap test result to override the Running flag from the bridge authority, such that bridges with their OR ports hidden do not always show as offline, instead using the reachability of their PT port. I have spent time focussed on getting hiro up to speed on working with the Metrics codebases. During August, we saw releases of metrics-lib and Onionoo, including work on the overload-* lines in server/extra-info descriptors, that should give new insights into bottlenecks in the network. Finally, I have been around in Matrix/IRC to answer Metrics questions and on occasion to provide a little end-user support in #tor. Thanks, Iain.
