I bumped out some more bad relays
by Roger Dingledine 10 Dec '21

10 Dec '21

Hi folks, I spent some time this week refining a new exit scanner, and today we pushed some new reject rules to kick out some relays that we confirmed were running mitmproxy to do more sslstrips. For past context, see these urls: https://blog.torproject.org/bad-exit-relays-may-june-2020 https://lists.torproject.org/pipermail/tor-relays/2020-July/018656.html https://lists.torproject.org/pipermail/tor-talk/2014-July/034219.html Expect some upcoming next steps that aim to change the fundamental arms race, including experiments to use https by default in Tor Browser, either via HTTPS Everywhere's "Encrypt All Sites Eligible" option (you can turn that on right now) or via Firefox's upcoming built-in version of the idea: https://gitlab.torproject.org/tpo/applications/tor-browser/-/issues/19850 For completeness, I'm including below the set of fingerprints that we bumped out. Note that we didn't confirm misbehavior from all of them -- some of them we're bumping out because they seemed sufficiently similar to the confirmed ones. If any of these are your relays, please speak up! Thanks, --Roger Group #1: COMID (coronamitmdisease2019) at OVH 019839E66C7229039367BEB4E83B27D08A9C2B37 110F26C0BFB2122BBB856EADC9A2D497989DE949 1B473D4B5C1D7C594E88B3044823D04E2BC51DBA

Dropped off consensus (0.4.4.5)
by Felix 23 Oct '21

23 Oct '21

Hi everybody This is early. Yesterday I upgraded Ichotolot60 1AE039EE0B11DB79E4B4B29CBA9F752864A0259E from 4.2.7 to 4.4.5. Now I see in the consensus health: moria1 Fast Run Stab V2Dir Valid bw=566 tor26 Fast Guard Stab V2Dir Valid dizum Fast Guard Stab V2Dir Valid gabel. Fast Stab V2Dir Valid bw=1130 danne. Fast Guard Run Stab V2Dir Valid maatu. Fast Stab V2Dir Valid bw=1200 farav. Fast Guard Run Stab V2Dir Valid bw=2970 longc. Fast Stab V2Dir Valid bw=490 bastet Fast Guard Run Stab V2Dir Valid bw=3520 And _no_ Authority "owns" the relay. Old Apr 02 21:51:31.872 [notice] Tor 0.4.2.7 running on FreeBSD with Libevent 2.1.11-stable, OpenSSL LibreSSL 3.0.2, Zlib 1.2.11, Liblzma 5.2.4, and Libzstd 1.4.4.

(Yeah, some Lib stuff is new too, hehe) The "Guard !Run Stab" consensus looks quite interesting to me. How can it be? Other relays with that nice "Guard !Run Stab" dropped off consensus over night (or since days) and no authority "owns" them too: HORUS1 0.4.4.4-rc norisknofun 0.3.5.10 ULayerKiriakou 0.4.3.5 Stellvia 0.4.3.6 torexit42 (StaleDesc) 0.4.1.6 torpidsDEhetzner1 0.4.3.2-alpha (3 days) karen (StaleDesc) 0.4.2.7 Stephen304 0.4.2.7 (3 days) Rigel2020 (StaleDesc) 0.4.3.6 dgplug (FallbackDir, StaleDesc) 0.4.4.5 =?= May-be the operators updated and are now in the same floating position? May-be this is super normal and came to my attention by surprise? Anyways, I let everthing run for a day or so. Time can heal. -- Cheers, Felix

Is my relay broken? No stable, hsdir or guard flags
by raltullou＠posteo.org 17 Feb '21

17 Feb '21

Hi, I'm looking for help because I can't figure out what's going on. https://metrics.torproject.org/rs.html#details/11DF0017A43AF1F08825CD5D9732… - At the beginning of January the relay seems to have lost the guard flag - A week ago I checked and noticed that the relay had also lost the stable flag despite having an uptime of >2 months at that point - A week ago I rebooted the server but the situations hasn't changed - flags are still gone - metrics.torproject graphs show that the server has been transmitting data the entire time - so it doesn't seem like I missed some downtime - Serverlogs show no problems - Relay has been running continuously for almost 4 years and only gets rebooted for kernel/tor upgrades -> so uptime and MTBF should not be a problem Is there a problem on my side? Is there anything I can do or check? It is a fallback relay - is it still useful as such? TY

Exit relay operators please help test #2667 branch
by Roger Dingledine 04 Feb '21

04 Feb '21

Hello friendly relay operators, Another day, another weird thing with the Tor network. This time we have some jerk bombing the directory authorities with directory fetches, and doing it via exits: https://lists.torproject.org/pipermail/network-health/2021-January/000661.h… The network is mostly holding together, but I wouldn't say it is pretty. One of the long-term fixes will be ticket #2667: https://gitlab.torproject.org/tpo/core/tor/-/issues/2667 where exit relays refuse to let users connect back into the Tor network. David and I made a branch this evening that implements #2667, and it could use some testing. If you're comfortable building your exit relay from a git branch, please do, and let us know how it goes. It is the "ticket2667" branch on either https://git.torproject.org/user/arma/tor or https://gitlab.torproject.org/arma/tor/ And if your relay is currently using 100% cpu and/or way more bandwidth than usual, you might be especially excited to try out this patch. :) When the defense triggers, you will see an info-level log line like "%s tried to connect back to a known relay address. Closing." (where %s is the destination, so don't get upset at them. :) You can let us know how it's going either by mail just to me, or by a reply on the list, whichever you prefer. Once we know that you're running the branch, we can also probe your relay remotely to verify that it is correctly refusing those connections. Thanks! --Roger

Re: [tor-relays] Noob query, wish to run a bridge relay for tor community.
by ramesh bhootra 27 Jan '21

27 Jan '21

Hi, I have been using Tor since a decade, always had limited resources and couldn't give back anything to the community. Now I wish to run relays in an effort to give back something. Right now I have a 100 mbps reliable internet connection on a gaming laptop with windows 10 "HP Envy K204tx", I disabled windows updates, and a good quality ethernet cable. Even though it's a laptop, I use it like a desktop, with hdmi out to a TV, ethernet cable, usb hubs and 24x7 electricity with lots of inverter (home ups) backup. I keep this laptop always stationary since I have another sleek and lightweight one which I use for portable purposes. Earlier my internet plan was limited to 500 gb per month but recently they upgraded it for free, now it's 3000 gb per month, which is too much for me and my family, we hardly use 300-400 gb per month. I was thinking about running a relay for Tor, (maybe a bridge relay) at night since both my laptop and internet are unused at night. I have following queries: 1. Can I run relay on my laptop simultaneously while using other internet services and browsers normally? 2. Is it possible to schedule everything automatically, say to run a relay from 1 am to 7 am then shut it down automatically after that? I start using it at 9 am and 2 hours of rest will be enough for the laptop. 3. I have Kaspersky internet security, will it create problems for running tor relays? Currently when I use tor browser as a client, I don't have any issues, kaspersky doesn't provide a warning, doesn't block any connections. 4. Do I need to be punctual in running the relay every day at the scheduled time? Is it okay if I can't run the relay on a few occasional days, for reasons like power outage, feeling sick, too busy etc? 5. Can I use a Tor browser (client) while running the relay? If yes, will I get faster browsing speed with that? >

build tor out of source -> permission problems?
by Patrice Bönig 27 Jan '21

27 Jan '21

Hi @ list, I am operating a relay for several years and I really do like it and will do it for more years. My current relay residents on Pi 4. At first I installed it via apt but now the 32 Bit sources are no longer available. So I thought I could build the from source. The building process went well but now I have a problem with the user permissions. I can't get tor really running. _My first attempt was:_ To start tor with "systemctl start tor". But tor won't start and " journalctl -u tor" says only this: Jan 22 09:06:23 rpi4tor systemd[1]: Starting LSB: Starts The Onion Router daemon Jan 22 09:06:23 rpi4tor systemd[1]: Started LSB: Starts The Onion Router daemon Jan 22 09:08:32 rpi4tor systemd[1]: Stopping LSB: Starts The Onion Router daemon Jan 22 09:08:32 rpi4tor systemd[1]: tor.service: Succeeded.

Jan 22 09:08:32 rpi4tor systemd[1]: tor.service: Succeeded. Jan 22 09:08:32 rpi4tor systemd[1]: Stopped LSB: Starts The Onion Router daemon processes. _My second attempt was:_ I changed the user of all tor files to the current user "pi". After that I was able to start tor with "tor --quiet" as user "pi". All went fine until I rebooted the system and all my changes to "pi" where changed to "debian-tor". _My third attempt was:_ I did "sudo tor --quiet". It works, but in "notices.log" is the information that I shouldn't do that. So, now I am standing here and don't know what to do. I would like to start tor via systemd but I don't know what's wrong (maybe the permissions). Does someone has a hint for me? regards, Karl

Server lost Stable flag but has more than 60 days uptime
by raltullou＠posteo.org 26 Jan '21

26 Jan '21

Hello list, I'm trying to find out why the server (https://metrics.torproject.org/rs.html#details/11DF0017A43AF1F08825CD5D9732…) has lost its stable flag. As far as I can see it is running a recent version of tor and has an uptime of over 60 days. Are there other reasons that factor into the Stable flag? The log file doesn't give my an indication that there is anything wrong, either. Any ideas?

Server under attack according to my hoster
by lists.torproject.org＠stein-io.de 22 Jan '21

22 Jan '21

Hi folks, I have a dedicated Server running with the red H in Germany. https://metrics.torproject.org/rs.html#details/1CD48F4ED0F1821FFBF1940802A1… Today I received a notification that my server is "under attack" since my server got over the threshold of 300k packets/s. At the time of the mail it seems to be about 450k pps . I checked a couple of IPs and most of them are other TOR-Relays or Exits. Would you recommend telling my Hoster that everything is all fine? Cheers

Hi, How do you block bittorrent nowadays? I read this page: https://gitlab.torproject.org/legacy/trac/-/wikis/BlockingBittorrent but http://www.trackon.org/api/all doesn't work anymore because the domain is expired. Do you know any alternatives? Sent with [ProtonMail](https://protonmail.com) Secure Email.
