## Tor Relay Operator Meetup - June 2022
### Notes
0. Review Agenda
1. Tor Project updates:
- Hackweek - https://hackweek.onionize.space/hackweek/talk/#0
https://forum.torproject.net/t/online-hacking-week-at-the-tor-project/3594
- Sysadmin 101 workshop update
https://gitlab.torproject.org/tpo/community/relays/-/issues/36#note_2816664
- should it be repeated with tweaks or maybe other languages, or
move on to a 200-level class?
2. The ongoing d(d)os:

6. Next meetup: we will announce on Tor relays mailing list :)
Note that there will be an in-person relay operator meetup at MCH in the
Nederlands, sometime in the July 22-26 range. Stay tuned for details:

7. Q & A
Add your questions here and we will try to answer them all!
- Because of DDoS. Has anyone with their own AS ever used the Team Cymru
service? https://team-cymru.com/community-services/utrs/
If the answer from anybody is yes, please share your experience on
the tor-relays@ list!
- Is the current DDoS defense (tuning the number of circuits that can be
built) actually working? Or is it denying service to honest users too?
https://metrics.torproject.org/hidserv-rend-relayed-cells.html
Answer: nobody knows yet! Maybe we are harming performance for
honest users? Maybe we are reducing the DDoS or maybe we're not even
doing that? We will look further on Monday.
Long term the fix is to implement the proof-of-something proposals:
- https://gitweb.torproject.org/torspec.git/tree/proposals/327-pow-over-intro.txt
-https://gitweb.torproject.org/torspec.git/tree/proposals/331-res-tokens-for-anti-dos.md
It is unclear whether the current DDoS is the same as the one we saw
a year ago, where some jerk was trying to knock an onion service off
the network and they did it by sending millions of introduction
attempts. It seems plausible that it is related / similar.
- DDos: is it getting worse(10Gb/s normally upto 40Gb/s now)
http://hctxrvjzfpvmzh2jllqhgvvkoepxb4kfzdjm6h7egcwlumggtktiftid.onion/hidserv-rend-relayed-cells.html
- A few weeks ago we had 100Gb/s DDoS against our AS AS208294 in Berlin.
Therefore my ixbge driver killing problems.
- It would be good to get some network team people attending these relay
operator meetups -- to be able to answer questions and explain what
the network team has been doing on the network lately. (In some past
ones we had ahf and that was useful, but it doesn't necessarily need to
be ahf.)
- What are the links to the reddit discussion where people were
surprised to learn that the network health team was reaching out to
relay operators to meet them?
- https://www.reddit.com/r/TOR/comments/v8nmdp/tor_relay_family_100_servers_blocked_for_refusing/
- There is also a link on the forum with further discussion:
https://forum.torproject.net/t/tor-relay-family-100-servers-blocked-for-refusing-kyc-procedure/3607
- The reality is much more nuanced than those people presented in that
reddit discussion. GeKo and gus explain in more detail.
- Is torservers.eu related to torservers.net? No
What is torservers.eu? Seems like a blank page? Must be fake,
torservers.net is actual leibi (CCCS)
- Speaking of relay operator meetups, who is going to MCH?
- ahf has a Tor talk there. I hear a lot of people are going!
- Add your name here if you want. :)
- Artikel10 folks will be at MCH! <3
- what About the Gamification project That was Presented 3 months ago?
It was a 3-month internship. We did part of the user experience
(UX). Because of timing, we made some mock-ups of the ideas. We
don't have capacity to move it forward quite yet but we still have a
goal of setting up a gamification portal. Ideally we want to integrate
these points into the metrics portal.
- Is there an output posted anywhere? Blog post? Collection of images?
Gitlab ticket?
Yes, it's all on gitlab:

- https://gitlab.torproject.org/tpo/community/relays/-/issues/39
- https://gitlab.torproject.org/tpo/community/relays/-/issues/38
mockups:
- https://gitlab.torproject.org/tpo/community/relays/-/issues/37
ideas:
- https://gitlab.torproject.org/tpo/community/relays/-/issues/30
- why isn't the forum promoted as much as other means of communication ?
there are many resources on it
When you send mail to the tor-relays@ list, that post gets mirrored
onto the forum. So when we share these posts on social media, we
share the forum url because it is how people can engage with the thread.
- Can you announce somewhere when there are alerts (on the status page) like a DDoS attack ?
Hm! There are many different topics and audiences in mind for that page,
e.g. we use it for saying when gitlab is broken too.
For relay issues, it's unclear what we should do. We should think about
it and make a better plan. E.g. if it is about the network, then we
should tell tor-relays@ when we add a status entry that has to do with
the network.
- Running a relay operator meetup during the weekday, rather than always
the weekends?
Eventually we will try this idea yes. But not yet.
