Many parties [publicly] subscribe to such guidelines, many [silently] don't. That's the nature [and one of the risks] of such networks, indeed of any network. Such adversaries exist and are highly active and capable. Know your adversary. Strengthen your designs to match and best them. As to the nodes, they're all planet-lab.net hosts, planetlab has at least two known tor slices "okstate_tor" and "uml_ZhenLing", some public research outputs [or not] of which might be listed below... https://www.cs.uml.edu/~xinwenfu/paper/TorCellSize_ICC11_Fu.pdf https://www.cs.uml.edu/~xinwenfu/paper/TorWard14_Fu.pdf http://cse.seu.edu.cn/PersonalPage/zhenling/publications_files/infocom2014_… http://cse.seu.edu.cn/PersonalPage/zhenling/publications_files/infocom2013_… http://cse.seu.edu.cn/PersonalPage/zhenling/publications_files/infocom2012_… https://news.okstate.edu/articles/communications/2015/tedx-returns-oklahoma… https://www.youtube.com/watch?v=9QsjkJcUznA MEMEX Christopher White ‎Jiangmin yu, Eric Chan-Tin: Realistic Cover Traffic to Mitigate Website Fingerprinting Attacks DOI: 10.1109/ICDCS.2018.00175 Conference: 2018 IEEE 38th International Conference on Distributed Computing Systems (ICDCS) Identifying Webbrowsers in Encrypted Communications DOI: 10.1145/2665943.2665968 Revisiting Circuit Clogging Attacks on Tor DOI: 10.1109/ARES.2013.17 Conference: Availability, Reliability and Security (ARES), 2013 Eighth International Conference on https://chantin.cs.luc.edu/~chantin/ARES2013.pdf Application Of Data Analytics - Case Studies https://shareok.org/bitstream/handle/11244/54637/Yu_okstate_0664D_15098.pdf

Hi bf@ctct, thanks for adding tor relays. If you are using them for research purposes please ensure you follow the safety guidelines: https://research.torproject.org/safetyboard.html You care currently not setting the MyFamily option on your relays, which puts tor users at risk. Please configure your relays with MyFamily. more information: https://medium.com/@nusenu/some-tor-relays-you-might-want-to-avoid-5901597a… https://trac.torproject.org/projects/tor/wiki/doc/ReportingBadRelays#Whatis… | Up | Ext | JoinTime | Nickname | Version | IP | AS | CC | ORp | Dirp | OS | Contact | eFamMembers | FP | |------+-------+------------+--------------+-----------+-----------------+------------------------------------------+------+-------+--------+-------+---------------+---------------+------------------------------------------| | 1 | 0 | 08:03:03 | butterfly002 | 0.3.5.7 | 200.129.132.19 | Associa\u00E7\u00E3o Rede Nacional de En | br | 9001 | 9030 | Linux | bf(a)ctct.org | 1 | 508BDBDA23A6B76D3C5B2D17DBEA2A4E170859BD | | 1 | 0 | 09:40:10 | butterfly003 | 0.3.5.7 | 216.48.80.12 | University of Ottawa | ca | 9001 | 9030 | Linux | bf(a)ctct.org | 1 | 09F83FDF39A459D91AB8EC18B44A7F389BB5D87C | | 1 | 0 | 09:47:23 | butterfly004 | 0.3.5.7 | 200.17.202.195 | Fundacao da UFPR para o DCTC | br | 9001 | 9030 | Linux | bf4(a)ctct.org | 1 | 7BA8CCC7EFE0D6ED1386173631CC825CB39D6F6F | | 1 | 0 | 11:12:56 | butterfly005 | 0.3.5.7 | 129.97.74.12 | University of Waterloo | ca | 9001 | 9030 | Linux | bf5(a)ctct.org | 1 | ECFFC5A820CBFD37AC2F85AA2C8DC77F87796F16 | | 1 | 0 | 12:07:56 | butterfly006 | 0.3.5.7 | 200.19.159.35 | Associa\u00E7\u00E3o Rede Nacional de En | br | 9001 | 9030 | Linux | bf6(a)ctct.org | 1 | F1F92CC70007DB1EB63B28623B8481863ED3B29F | | 1 | 0 | 12:22:19 | butterfly007 | 0.3.5.7 | 128.8.126.111 | University of Maryland | us | 9001 | 9030 | Linux | bf7(a)ctct.org | 1 | FCA01B39D2CA5DAE896EAAABDB010B0040D068EF | | 0 | 0 | 11:56:55 | butterfly008 | 0.3.5.7 | 192.33.90.67 | SWITCH | ch | 9001 | 9030 | Linux | bf8(a)ctct.org | 1 | 2447A5A12AC3DB748317F97E3317814C42BF0380 | | 1 | 0 | 13:10:27 | butterfly008 | 0.3.5.7 | 133.69.32.131 | Asia Pacific Advanced Network - Japan | jp | 9001 | 9030 | Linux | bf8(a)ctct.org | 1 | 748653AF527B393EFB5870DFA840F8FD578E19BA | | 1 | 0 | 12:36:30 | butterfly009 | 0.3.5.7 | 188.44.50.106 | Federal State Educational Institution of | ru | 9001 | 9030 | Linux | bf9(a)ctct.org | 1 | DCC2DD20CC44DC617A859EA9EFE1A40C5215CAC0 | | 1 | 0 | 13:28:32 | butterfly010 | 0.3.5.7 | 134.117.226.180 | Carleton University | ca | 9001 | 9030 | Linux | bf10(a)ctct.org | 1 | FD82A15B62B73DF4CE20003B651CBB7384C37539 | -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu

Hello, i'm a student, so I lack many networking notions. Which are the most privacy reliable public dns servers? I don't exactly know how choose a third part DNS server. I read that cloudfare servers are audited by third parties but I'm not sure that I can trust. do you think that audition is trustworthy? Thanks -- Inviato dal mio dispositivo Android con K-9 Mail.

Bandwidth limiting at relay or network?
by Isaac Grover, Aileron I.T. 17 Jan '19

17 Jan '19

Good evening fellow relay operators, I haven't ever taken the time to configure bandwidth limits in torrc, always preferring to manage it at the firewall as we have other bandwidth limits set there as well. However, I'm curious - what do other relay operators prefer? Make your day great, Isaac Grover, Senior I.T. Consultant Aileron I.T. - " Because #ProactiveIsBetter " O: 715-377-0440<tel:715-425-0440>, F:715-690-1029<tel:715-690-1029>, W: www.aileronit.com<http://www.aileronit.com/> LinkedIn: https://www.linkedin.com/in/IsaacGrover/ YouTube: https://www.youtube.com/channel/UCqrwZNFKdR-guKtuQzFPObQ

Consensus weight drops continuously 28h after getting guard flag
by Ilka Schulz 15 Jan '19

15 Jan '19

Hi, approx. 28 hours after getting the guard flag, my relay <https://metrics.torproject.org/rs.html#details/A99B0D9E5FD5BC3C8F2D006EC91F…>'s consensus weight hit a peak and has declined rather rapidly since then (again 28 hours ago). Did I do something wrong? Is it because I restarted the relay 52 hours ago? Is there actually any detailed documentation on how consensus weight is calculated? Also, my bandwidth (as well as my cpu, etc.) is only used to a fraction of its capacity, even though my relay is three weeks old now. The /RelayBandwidthRate/ option does not limit here... Regards, Ilka

Torproject onion-repo down (sdscoq7snqtznauu.onion/torproject.org) ?
by petrarca＠protonmail.ch 15 Jan '19

15 Jan '19

Is it just me having issues - today, I couldn't reach the onion-repository of torproject.org at sdscoq7snqtznauu.onion anymore. It was working until very recently though. Everything else is working fine (internet, other onion services, etc.) and I didn't change anything really (just an upgrade to tor 0.3.5.7)...

Fallback Directory Mirror
by [REDACTED] 14 Jan '19

14 Jan '19

Hi, i run 17 Entrys and one bridge at the moment. I dont plan to change the IP adresses or the ports and most of them are already paid for nearly two years and i dont see a reason to switch them off after that time so if more fallback directory mirrors are needed then feel free to add them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ome of them are still pretty new but i am sure they will get older:)
