more minutes from the sysadmin meeting: 2025 roadmap
by Antoine Beaupré 18 Nov '24

18 Nov '24

Hi! So TPA had another meeting, and this time, we've made a roadmap! For your convenience, a cleaned up copy is in: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/roadmap/2025 Otherwise here are our minutes: # Roll call: who's there and emergencies anarcat, groente, lelutin, zen # Dashboard review ## Normal per-user check-in * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… # Tails merge 2025 roadmap In the previous meeting, we found consensus on a general plan. Now we nailed down the things we actually do in 2025 in the [Tails merge timeline][]. [Tails merge timeline]: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-73-tails-… We made those changes: - move monitoring up to 2025: retire tails' icinga! - start thinking about authentication in 2025, start brainstorming about next steps Otherwise adopt the timeline as proposed for 2025. # 2025 roadmap brainstorm Throw ideas in the air and see what sticks about what we're going to do in 2025. Following, of course, priorities established in the Tails roadmap. ## Tails: What we promised OTF For Tails: - [B.2: Keep infrastructure up-to-date and secure][] [B.2: Keep infrastructure up-to-date and secure]: https://nc.torproject.net/s/eAa88JwNAxL5AZd?path=%2FGrants%2FOTF%2F2024%20-… > As in Year 1, this will involve the day-to-day work needed to keep the > infrastructure we use to develop and distribute Tails up-to-date. This > includes our public website, our development servers for automatic builds > and tests, the translation platform used by volunteers to translate Tails, > the repositories used for our custom Debian packages and reproducible > builds, etc. Progressively over Year 2 of this contract with OTF, as Tails > integrates within the Tor Project, our sysadmins will also start maintaining > non-Tails-specific infrastructure and integrate internal services offered by > Tails within Tor’s sysadmin workflow TL;DR: maintenance work. Very few hours allocated for sysadmin work in that project. ## TPA We made a roadmap based on a brain dump from anarcat in [tpo/tpa/team#41821][]: [tpo/tpa/team#41821]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41821 - Web things already scheduled this year, postponed to 2025 - Improve websites for mobile - Create a plan for migrating the gitlab wikis to something else - Improve web review workflows, reuse the donate-review machinery for other websites (new) - Make a plan for SVN, consider keeping it - MinIO in production, moving GitLab artifacts, and collector to object storage, also for network-health team (contact @hiro) (Q1 2025) - [Prometheus phase B][]: inhibitions, self-monitoring, merge the two servers, authentication fixes and (new) autonomous delivery - Debian trixie upgrades during freeze - Puppet CI (see also merge with Tails below) - Possibly take over USAGM s145 from @rhatto if he gets funded elsewhere - Development environment for anti-censorship team (contact @meskio), AKA "rdsys containers" ([tpo/tpa/team#41769][]) - Possibly more hardware resources for apps team (contact @morganava) - Tails 2025 merge roadmap, from the [Tails merge timeline][] - Puppet repos and server: - [Upgrade Tor's Puppet Server to Puppet 7][] - Upgrade and converge Puppet modules - Implement commit signing - EYAML (keep) - Puppet server (merge) - Bitcoin (retire) - LimeSuvey (merge) - Website (merge) - Monitoring (migrate) - Come up with a plan for authentication [Upgrade Tor's Puppet Server to Puppet 7]: tpo/tpa/team#41819 [tpo/tpa/team#41769]: https://gitlab.torproject.org/tpo/tpa/team/-/issues/41769 [Prometheus phase B]: https://gitlab.torproject.org/groups/tpo/tpa/-/milestones/14 Removed items: - Evaluate replacement of lektor and create a clear plan for migration: performance issues are being resolved, and we're building a new lektor site (download.tpo!), so we propose to keep Lektor for the forseeable future - [TPA-RFC-33-C][], high availability moved to later, we moved autononmous delivery to Phase B [TPA-RFC-33-C]: https://gitlab.torproject.org/groups/tpo/tpa/-/milestones/15#tab-issues -- Antoine Beaupré torproject.org system administration

Based on Tor node families (over 3000) discovered from live Tor network data (from Jan. 2011 to Dec. 2012), a few characteristics of Tor node families were revealed, such as family size, bandwidth, geographical distribution as well as operators providing a few big families. The analysis validated the irreplaceable role played by family design in enhancing Tor's anonymity. Based on the measurement, security analysis showed the serious availability threat a compromised node family can cause to the Tor network. Besides, It also discussed Tor hidden families and the potential anonymity risk caused by them. == Reading group == * We will discuss "" on * * 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? == Updates == Name: This week: - What you worked on this week.

mailman 2 retirement imminent
by Antoine Beaupré 13 Nov '24

13 Nov '24

Hi everyone! This is hopefully (again!) my last email about Mailman 2 ever. Normally, everything should be up and running on Mailman 3. You should have everything you need there. Next week, I will be upgrading the main mail server, eugeni, where Mailman 2 was running. This will mean the final retirement of mailman 2, along with all its metadata about lists. Note that some of those things did *not* carry over to the new server. With geko, we found some bans that didn't transfer properly for example. We also also needed to approve some pending messages on tor-relays. So I've restored the service for Mailman 2, temporarily. It should now be available at: https://mailman2.torproject.org/ It's protected by a username / password, try tor-guest, with no password. Note that this service is *not* meant to be kept running like this. This is just available to pick up your remaining stuff and move it over to Mailman 3. I'm going to give this a week and then shutdown the virtual host again. Let me know if you need more time to finish those checks! Finally, note that I've decided to keep all the mailboxes (`mbox`) files from the current archives, including public *and* private archives, from current *and* retired mailing lists, archived on the new mailing list server. That way we don't have to worry about losing data on retired lists. a. -- Antoine Beaupré torproject.org system administration

# Roll call: who's there and emergencies anarcat, gaba, groente, lavamind, lelutin, zen. There's significant noise in monitoring, but nothing that makes it worth canceling this meeting. # Dashboard review ## Normal per-user check-in Tried to make this section quick, but there were some discussions to be had: * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… ## General dashboards Skipped this section. * https://gitlab.torproject.org/tpo/tpa/team/-/boards/117 * https://gitlab.torproject.org/groups/tpo/web/-/boards * https://gitlab.torproject.org/groups/tpo/tpa/-/boards # Tails merge discussion Let's review the work Zen did. Our rough plan was: - confirm already identified consensus - try to establish consensus on remaining items, or at least detail controversies and blockers - establish what should be done in 2025, 2026, < 2030, > 2030 We followed the [TPA-RFC-73 Draft](https://gitlab.torproject.org/tpo/tpa/team/-/wikis/policy/tpa-rfc-73… as it was at the time the meeting started. We figured that today, we would agree on strategy (e.g. puppet merge), on the colors (e.g. which services are retired), and postpone the "what happens when" discussion. We also identified that most services above "low complexity" will require their own discussions (e.g. "how do we manage the Puppet control repo", "how do we merge weblate") that will happen later. ## Per service notes - Alternative to puppet merge: migrate services to TPA before moving Puppet, but not a good idea because some services can't be easily migrated. - registrars and colo could just depend on password store and not be otherwise changed. - website depends on powerdns - agreement of merging puppet codebases first - eyaml: merge for now, until people get familiar with both trocla and eyaml, but we probably should have a single system for this - virtualization: proposal: treat the old stuff as legacy and don't create new VMs there or make new hosts like those, if we need to replace hardware we create a ganeti box - weblate: - option 1: move the tor weblate to the self-hosted instance, need approval from emmapeel, check what reasons there were for not self-hosting - option 2: move tails translation to tor's weblate and rethink the translation workflow of tails We didn't have time to establish a 2025 plan, and postponed the rest of the discussions here. # 2025 roadmap brainstorm Throw ideas in the air and see what sticks about what we're going to do in 2025. Following, of course, priorities established in the Tails roadmap. Postponed. ## What we promised OTF For Tails: - B.2: Keep infrastructure up-to-date and secure > As in Year 1, this will involve the day-to-day work needed to keep the > infrastructure we use to develop and distribute Tails up-to-date. This > includes our public website, our development servers for automatic builds > and tests, the translation platform used by volunteers to translate Tails, > the repositories used for our custom Debian packages and reproducible > builds, etc. Progressively over Year 2 of this contract with OTF, as Tails > integrates within the Tor Project, our sysadmins will also start maintaining > non-Tails-specific infrastructure and integrate internal services offered by > Tails within Tor’s sysadmin workflow https://nc.torproject.net/s/eAa88JwNAxL5AZd?path=%2FGrants%2FOTF%2F2024%20-… For TPA: - I didn't find anything specific for TPA. https://nc.torproject.net/s/eAa88JwNAxL5AZd?path=%2FGrants%2FOTF%2F2024%20-… # Metrics of the month * hosts in Puppet: 90, LDAP: 90, Prometheus exporters: 504 * number of Apache servers monitored: 34, hits per second: 612 * number of self-hosted nameservers: 6, mail servers: 11 * pending upgrades: 0, reboots: 77 * average load: 1.03, memory available: 3.50 TiB/4.96 TiB, running processes: 321 * disk free/total: 65.69 TiB/139.85 TiB * bytes sent: 423.32 MB/s, received: 270.22 MB/s * planned bookworm upgrades completion date: 2024-10-02 * [GitLab tickets][]: 256 tickets including... * open: 2 * icebox: 162 * future: 39 * needs information: 4 * backlog: 27 * next: 11 * doing: 5 * needs review: 7 * (closed: 3760) [Gitlab tickets]: https://gitlab.torproject.org/tpo/tpa/team/-/boards Upgrade prediction graph lives at https://gitlab.torproject.org/tpo/tpa/team/-/wikis/howto/upgrades/bookworm/… Note that we have only a single "buster" machine left to upgrade after the Mailman 3 upgrade, and also hope to complete the bookworm upgrades by the end of the year.

cohosh's monthly status report, October 2024

Hi! This is my status report for contract work done in October 2024. I was AFK for the first half of the month. # Snowflake My main project last month was to add a snowflake transport to Lyrebird. This will help with reducing the PT binary size and simplify the process of integration with other applications (such as IPtProxy). https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/lyre… https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/lyre… I also worked on a few Snowflake fixes and features towards a similar purpose of making the Snowflake library more usable for other applications. https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow… # Pluggable transport libraries I've been working with Guardian Project on making our PT libraries more usable. Last month we started a rewrite of IPtProxy[0], which is a bundling of PT libraries for use with gomobile to produce java and Objective C bindings. This work has now been merged, and is just waiting for a few outstanding upstream changes before a release. [0] https://github.com/tladesignz/IPtProxy/pull/61

Hello everyone, This is a summary of the work I did in the month of October followed by a more detailed report of the work done by our user support team. With a number of Tor Browser releases including the last major stable release of the year - Tor Browser 14 - much of my work included alpha testing, updating the Tor Browser user manual[0] before the release. And reviewing and updating the documentation[1] on Support Portal and the various user support channels and keeping track of user feedback after the release. I worked on a number of Tor Browser related user support tickets - from general questions about installing, updating and troubleshooting to bug reports. With the onset of the year-end campaign[2], I also worked on related support tickets, answering questions about Tor Browser. Topics include downloading, installing, using the browser it's various privacy enhancing features and questions about the Tor network in general. Finally a huge part of my work was dedicated to help users in regions where Tor is censored which includes but is not limited to helping users with instructions to download Tor Browser binaries from GetTor and/or official mirrors, verifying Tor Browser's GPG signature, help with using censorship circumvention methods that works best for them and overall troubleshooting.

Rhatto's Monthly Status Report, October 2024

Hi all :) This is my monthly status report for October 2024 with the main relevant activities I have done, was involved or are related to my work during the period. # Onionprobe Ansible Role A considerable time was spent finding ways to structure and test Ansible roles, collections and playbooks through GitLab CI. Goal is to provide easier-to use procedures to manage Onion Services infrastructure. As a direct result of this research, it was possible to finally refactor and release an Ansible role to manage Onionprobe, a monitoring tool for onionsites: https://gitlab.torproject.org/tpo/onion-services/ansible/onionprobe-role It was interesting to research how to do basic Ansible tests using GitLab CI, and a special thanks goes to TPA for providing the base Podman image which allows running Podman in a GitLab CI job: https://gitlab.torproject.org/tpo/tpa/base-images # Onionprobe Onionprobe itself got some improvements, including support for running the standalone monitor node with Podman: https://onionservices.torproject.org/apps/web/onionprobe/standalone/ # OnionSec The OnionSec library and command line for testing onionsites got some enhancements as well: https://github.com/TheEnbyperor/onion-sec/pull/1 # Libraries The Onion Services Ecosystem got a Libraries page: https://onionservices.torproject.org/dev/libraries/ It still needs some improvements, and also some input from the upstream devs to check accuracy: https://gitlab.torproject.org/tpo/onion-services/ecosystem/-/issues/21 # Support Finally, also did the usual and ongoing sponsored work with deployment, maintenance and monitoring of Onion Services. -- Silvio Rhatto pronouns he/him
