What is the current method of submitting Tor-friendly ISPs for consideration?
by Isaac Grover, Aileron I.T. 18 Mar '22

18 Mar '22

Good afternoon from Wisconsin, Following up on a previous post to this list, I started contacting AS administrators in bulk and currently have five ISPs in unique ASs who state they can accommodate Tor exit nodes. The GoodBadISPs page on TP.o doesn't have a submission form or contact email address where I can submit the relevant info. Should I post them here or is there a better/preferred method? Thank you in advance, Isaac Grover

Possible compression bomb
by Tschador 18 Mar '22

18 Mar '22

Hi, today I found this message in my Tor relay log: Mar 17 14:26:17.000 [warn] Possible compression bomb; abandoning stream. Mar 17 14:26:17.000 [warn] Unable to decompress HTTP body (tried Zstandard compressed, on Directory connection (client reading) with 86.59.21.38:80). What does it mean? Regards

Moving Bridges
by Eddie 12 Mar '22

12 Mar '22

One of my bridges has just taken on a slew of new connections. Over the last few days it's gone from an average of around 15 users to over 300 (according to tor metrics. The logs show over 1,000 unique clients for the same period). Unfortunately with the VPS provider I'm using, this isn't sustainable as I'll probably blow my bandwidth allowance in a matter of days and the excess charges are crazy. So I'm looking to move both my bridges to a new VPS, which unfortunately is probably going to p!ss off the 300 plus folks who have just found my bridge only for it to promptly disappear, as I'm certain that there's no way to "move" them to the new location and have a couple of questions. I'm guessing that the only advantage in copying over the keys directory is that the historical statistics will remain. Is there any reason to copy over the pt_state directory, to retain the same bridgeline information. Cheers.

Flooding of unbound via resolve attempts
by Georg Koppen 11 Mar '22

11 Mar '22

Hello! As you might know we are doing regular (at the moment weekly) scans of exit nodes to find and help with misconfigurations or errors that have potentially serious effects for Tor network usability and performance. The results we got so far after over a year of scanning are roughly single digit numbers of exit relays per week having mostly DNS configuration issues (unbound crashed etc.) However, this week we suddenly found almost 80 exit relays with malfunctioning DNS resolution[1] which was surprising. Additionally, after some of the servers got fixed the issue returned. DrWhax (thanks!) pointed us to a possible explanation twittered by the unredacted folks: https://twitter.com/unredacted_org/status/1501458345219215363 It seems that someone (intentionally or not) is overwhelming unbound leading to DNS resolution issues for those exit operators that do run this local resolver, which we currently recommend. We've opened a ticket[2] for further investigation, but I hope this email raises some awareness so that exit operators can keep and eye on the situation. Feel free to add insights you have to the ticket. Additionally, I bet if someone would share how they do monitoring for such a problem on their exits then a lot of exit operators would be happily picking up that setup and the Tor network would win. :) Thanks, Georg [1] https://gitlab.torproject.org/tpo/network-health/team/-/issues/197 [2] https://gitlab.torproject.org/tpo/network-health/analysis/-/issues/30

Auto-discovered IPv6 address [...] has not been found reachable.
by Onion Operator 11 Mar '22

11 Mar '22

Hi Need another couple of eye balls on my relay, RealityLeighWinner. I keep reading "Auto-discovered IPv6 address [2a02:a446:5ef1:1:d072:53ff:fef4:ea59]:443 has not been found reachable..." in the logs but I actually can reach it with openssl s_client from another ipv6 box not in the same network. Could please anybody double check and maybe explain this behavior? Thanks. Oo.

Ansible role to deploy Bridges
by Erasme - Relay Operator 09 Mar '22

09 Mar '22

Hi all, In the effort of deploying obfs4 bridges for the community we are sharing our Ansible role that allowed us to deploy multiple nodes: https://github.com/NewNewYorkBridges/ansible-tor-bridge For now it is only available on Debian but we will make it available for other distributions. We hope this role is helpful for the community. Feel free to send us your feedback! Kind regards, Erasme

Good hosting providers for an exit node
by Charles Bevitt 07 Mar '22

07 Mar '22

I run a middle relay at home but now I’m planning to also lease a VPS to run an exit node. I’d appreciate any suggestions for a good hosting provider. My first choice would have been BUYVM, but it seems they’re always out of stock. This will be my first time working with a VPS and Linux, so wish me luck! Chuck Bevitt Sent from my iPad

FreeBSD DNS/tor version question
by George 07 Mar '22

07 Mar '22

At Saturday's relay ops events, someone had issues with a FreeBSD relay. I believe the issues were related to DNS and the tor version. Please feel free to raise those questions here, or on IRC at #tor-relays. g
