Moving gitlab to our Dallas cluster on Thursday 2024-11-28
by Gabriel Filion 21 Nov '24

21 Nov '24

Hello, Additionally to the mail server switch on Monday, we're planning to move/migrate the gitlab server from our Falkenstein-based cluster to the one in Dallas. This move will be happening on Thursday november 28th starting at 18:00 UTC. The disks for the gitlab server are fairly sizeable so the transfer could be taking a long time. Our current estimates are that it could take about 18 hours to transfer. We will try launching an operation to zero out empty parts of the disk volumes before starting the transfer in the hopes that it could give the transfer a boost. So the transfer will most likely take gitlab offline until the next day, friday 29th, at which time we'll make sure that the service is coming back online properly. If there's any issue during the outage, please reach out to us via IRC or email, but not through gitlab issues since this last one will obviously be offline at that time. For status updates, see: https://status.torproject.org/issues/2024-11-28-gitlab-migration/ Cheers!

Switching mail servers on Monday 2024-11-25
by groente 21 Nov '24

21 Nov '24

Hey everyone, On November 25st 2024, starting at 11:00 UTC, we will be switching to new mail servers for receiving and forwarding mail sent to torproject.org. If all goes well, there will be no downtime and deliverability to external providers like gmail will improve. If all does not go well, please reach out on IRC or file an issue on Gitlab, do not mail TPA since e-mail may obviously not be reliable. For more details on how to get in touch and how to report e-mail problems, see: https://gitlab.torproject.org/tpo/tpa/team/-/wikis/support For status updates, see: https://status.torproject.org/issues/2024-11-25-switching-mail-servers/ Fingers crossed :) x, groente

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

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

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.

Tor Project + SEEKCommons Fellowship Opportunity Now Available for 2025!
by gus 09 Nov '24

09 Nov '24

Hello, I'm writing to let you know that applications are now open for the second SEEKCommons Fellowship[1] cohort. The SEEKCommons Fellowship program is funded by NSF and run by partners at University of Notre Dame, University of California Davis, University of Michigan, University of Virginia, and The HDF Group. The goal of the fellowship is to bring graduate students, post-doctoral researchers, and professionals from community-based organizations with new perspectives to socio-environmental research with open technologies. Application deadline is Dec. 15, 2024. The fellowship is designed to: - Encourage new translational and integrative work involving socio-environmental action research with Open Science practices; - Provide a space for Fellows and Network members to collaborate on common research issues, challenges, and solutions. Fellows may be: - Graduate students working with open technologies on socio-environmental issues; - Post-docs with existing community projects in Science and Technology Studies, Open Science, and/or Socio-environmental research; and/or - Community practitioners who are interested in integrating common technologies into their environmental justice work. The SEEKCommons website contains all the necessary fellowship information, including the application link. https://seekcommons.org/fellowship-application.html Partnership SEEKCommons + Tor Project ===================================== This year SEEKCommons is reserving one fellowship to sustainability studies of community networks in partnership with the Tor Project! We welcome Fellowship applications on the sustainability of the Tor network with a focus on energy consumption and relay metadata (such as ASN, uptime, and platform). The goal of the partnership between SEEKCommons and Tor is to study the environmental impact of community networks and promote the use of renewable energy in decentralized infrastructures. We would like to support applications that address one (or more) of these questions: - What Free and Open Source technologies can be used to promote a more sustainable and distributed Tor infrastructure? - How can the energy consumption of the Tor network be measured and optimized to reduce its environmental impact? - How can the "Tor Snowflake" decentralized proxy model be used to improve the sustainability of the network? - How can we use metadata from relays (e.g., ASN / uptime / platform) to assess the environmental impact of the network? - What open hardware and renewable energy sources could be used/reused in the Tor network? More information: https://seekcommons.org/partnership-tor.html If you have any questions, please don't hesitate to reach out. Thank you so much! Warmly, Gus [1] https://seekcommons.org/about.html -- The Tor Project Community Team Lead

cohosh's monthly status report, October 2024
by Cecylia Bocovich 05 Nov '24

05 Nov '24

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
