Tor relays Bazinga and JPsi2 to be shut down
by Random Tor Node Operator 03 Jun '24

03 Jun '24

Hi all, I have been operating the relays - Bazinga B198C0B4B8C551F174FBB841A172616E3DB3124D - JPsi2 F6EC46933CE8D4FAD5CCDAA8B1C5A377685FC521 for about 10 years. The hosting provider stops providing their current service and their successor services are not Tor-friendly anymore. Hence, these relays will be shut down by June 2 2024. My third relay - SafeAndEffective A508096AA0C899F4E6ECD1D9C35037B89008BCBA is unaffected.

We need to talk about the latest DDoS affecting the Tor network
by koizoi 25 May '24

25 May '24

For several weeks now, users have been complaining (see https://www.reddit.com/r/TOR/comments/1cnmsdz/tor_extremely_slow_lately/, https://forum.torproject.org/t/is-there-currently-a-major-ddos-affecting-th…, etc) about degraded performance (slow speeds, timeouts) when using Tor, both to access v3 onion sites and clearnet websites. In my personal experience, most v3 onion services are responding so slowly that they're completely unusable. it turns out that's it not just people's imaginations, looking at charts on metrics.torproject.org, it can be seen that the time to complete a 5MiB request over Tor has increased substantially (https://ibb.co/tp1CHdh). All of this is very reminiscent of the large scale DDoS that affected Tor relay nodes in 2022-2023. Tor relay operators have reported "attacks" on their relays, but there haven't been many details about what kind of attacks are taking place, other than some people saying that they have been TCP SYN flooded. But (to me, anyway) SYN flooding doesn't really make a lot of sense as there are so many Tor relay nodes that would need to be attacked, (and misconfigured to allow a SYN flood attack to work), and even if it were a SYN flood, that would cause different behavior than what users have been seeing (preventing connections to the Tor network rather than slowing them down). I understand that DDoS attacks on the Tor network might be kind of a touchy subject, but it would be good if we could get some information from the project leadership as to what's going on, what is being done about it, and what Tor relay operators can do to help prevent attacks like these from happening.

disable conflux on exit relay?
by applied-privacy.net 13 May '24

13 May '24

Hello, conflux appears to be the primary source of bugs and crashes for us in the past few months and there have been numerous issues related to it on gitlab. from the tor manual page: ConfluxEnabled 0|1|auto If this option is set to 1, general purpose traffic will use Conflux which is traffic splitting among multiple legs (circuits). Onion services are not supported at the moment. Default value is set to "auto" meaning the consensus is used to decide unless set. (Default: auto) will ConfluxEnabled 0 disable it for tor acting as a client only or for relays as well? thanks! applied-privacy.net

Updating tor issue
by Keifer Bly 13 May '24

13 May '24

https://metrics.torproject.org/rs.html#details/79E3B585803DE805CCBC00C1EF36… Hi, so for my relay at the address above, when trying to update tor, suddenly getting the "updating from such a respiratory can't be done securly" message. Odd as this just suddenly started happening. Here is my sources file. What is the correct format for adding tor as a trusted source? Thanks. deb-src http://deb.debian.org/debian buster main ## Major bug fix updates produced after the final release of the ## distribution. deb http://security.debian.org/ buster/updates main deb-src http://security.debian.org/ buster/updates main ## Uncomment the following two lines to add software from the 'backports' ## repository. ## ## N.B. software from this repository may not have been tested as ## extensively as that contained in the main release, although it includes ## newer versions of some applications which may provide useful features. deb http://deb.debian.org/debian buster-backports main deb-src http://deb.debian.org/debian buster-backports main deb [trusted=yes] https://deb.torproject.org/torproject.org buster main --Keifer

response to zimmer family hitting max descriptor size
by code9n＠pm.me 07 May '24

07 May '24

Hi, re. # Questions & Answers * Q: zimmer family hitting max descriptor size https://gitlab.torproject.org/tpo/core/tor/-/issues/40837 Any news on a possible solution to this ongoing issue? tl;dr: more powerful relays rather than large numbers of them. *Please note I have very little idea what I'm talking about here and there's probably something I don't know about or just don't understand. If a family has a very large number of exit relays but the capacity of each one is not that great couldn't they just spend the same money on making existing relays more powerful rather than having more of them? If we're using VPSs then the limits applicable to single cores don't seem to apply the way they do to physical servers. I run a single non-exit relay but I get more traffic through it by having more RAM and multiple vCPUs. The VPS seems to act like it has one large, powerful core rather than the 5 smaller one's it 'actually' has. So if 'descriptors' refer to the number of relays not their capacity wouldn't this work? Side note: to get more bang for your buck you can ask your VPS provider to swap some storage for more vCPUs, that's what I did and it certainly seems to allow me to run more traffic through my one relay. It doesn't need that much storage anyway. So you get the same amount of traffic through fewer, larger relays. cheers,

Hi, Share this Ansible role for Webtunnel, with which you can install, configure, and operate Tor network Webtunnel bridges. Currently, it supports installing bridges on Debian, with support for other operating systems coming soon. Repository with the Ansible role for Webtunnel https://github.com/nvjacobo/webtunnel In the Ansible Galaxy repository https://galaxy.ansible.com/nvjacobo/webtunnel A small guide to use the role https://acuare.la/en/ansible-webtunnel-bridges-tor-network/ Feedback are welcome! Thanks, Jacobo

Is the C tor client DoSStreamCreation aware?
by tor_appliedprivacy.net 28 Apr '24

28 Apr '24

Hello, is the upstream C tor client implementation (in git main) aware of the DoSStreamCreation consensus parameters and defaults thresholds and respects them to avoid triggering these exit relay defenses? If that is currently not the case yet, would it make sense to make it aware so it will never try to create streams at a higher rate? Even if it would be aware already, it would not self limit currently because the current consensus does not enable DoSStreamCreationEnabled. thanks! tor(a)appliedprivacy.net
