IPv6
by xplato 16 Dec '21

16 Dec '21

Hi all, I was able to add IPv6 on four HardenedBSD relays I run however I have now noticed a number of malicious login attempts. I am wondering if there is some correlation with the IPv6 or just a coincidence? Best regards, Dan Sent from ProtonMail for iOS

Old question
by Qimam Fellowship 16 Dec '21

16 Dec '21

Hello, the Torproject. We launched relays and bridges 3 days ago, today we received a few emails from noreply(a)torweather.org saying that our relays are down. Your metrics website says our relays are offline, but in fact our VPS are online and tor daemon is running. The status of our bridges is displayed as online. We attached tor daemon log from one of our relays and list of our relays and bridges fingerprint. Is this an error on your metrics website and Tor Weather bot or we misconfigured something?

[Looking for feedback] An easier way to declare families
by Nick Mathewson 14 Dec '21

14 Dec '21

Hello, relay operators! I'm hoping to get some feedback from relay operators, particularly those who use the MyFamily option, about the best way to deploy proposal 321. You can read the proposal at: https://gitlab.torproject.org/tpo/core/torspec/-/blob/master/proposals/321-… The main idea of this proposal is to provide an easier way for relays to declare that they are in the same family. With proposal 321, each relay in the same family uses a cryptographic certificate to prove that it is in the same family as the others. (That's just a summary; see the full proposal at the link above for a write up of how it works, an a description of backwards compatibility issues.) Now, my question is, how can we make this approach as usable as possible? There are several different ways that we could have it work in practice: Option 1: Every family would have a shared secret. This would be a random file that you'd have to copy to every relay in the family when you set it up. The relays would use this shared secret to derive a shared private key. If this file is ever exposed (for example, if a relay is compromised), you'd need to make a new one, and copy it to every relay in the family. (Otherwise, an attacker could claim to be in your family.) We could provide a convenient function to make a new secure shared secret, something like: $ tor --new-family-secret <filename> Option 2: As above, except instead of the shared secret, it would be a shared ed25519 private key for the family. This would be an ed25519 private key that would have to be copied to every relay in the family. If this key is ever exposed (For example, if one relay in the family is compromised), you'll need to make a new one, and copy it to every relay in the family. (Otherwise, an attacker could claim to be in your family.) We'd provide a command to generate new keys; it would look something like: $ tor --new-family-key <keyfile> Option 3: Offline certificate generation with separate distribution. In this scheme, there would be an ed25519 private key for the family, but you wouldn't have to copy it to the relays. Instead, you'd have to generate certificates from the private key offline, and then copy those certificates to the relays. They would have a lifetime of N days; you'd need to make new certificates every N days. If a relay's certificate is exposed, you don't need to generate new certificates for the other relays. You just stop generating certificates for that one relay. If the offline private key were ever exposed, you'd have to generate a new one, and a new set of certificates. The interface would probably look something like: $ tor --new-family-key <keyfile> $ tor --make-family-certs --key <keyfile> --members \ <family_list_file> --out <certfile> --lifetime <n days> Then you'd do something like: $ for member in $(cat family_hostnames); do scp <certfile> member:/srv/tor/tor-family-cert done Option 3 requires regular updates to all the relays in the family, which makes it cumbersome. Its advantage is that if a relay is compromised, you don't need to re-key the family. Options 1 and 2 are less secure, since you have to re-key your whole family if the key is ever compromised. But they have the advantage that they don't take any maintenance in the regular case. Option 1 is a little more convenient than option 2, since you can use any old random file. But that makes it more error prone: if somebody chooses an insecure password as their random file, an attacker could guess it and become a family member. So... If all three of these options were available, which of these would you choose? Is there anything else that we could do to make this system simpler or easier to use? If I'm left to my own devices, I will probably just implement option 2 for now, but leave the door open for option 3 in the future. best wishes, -- Nick

bridge distribution mechanism
by potlatch 14 Dec '21

14 Dec '21

Hello Tor universe, One of the bridges I recently set up shows the Bridge distribution mechanism as https: Question: Is this an issue or does it impact the functionality of the bridge? Or maybe I made a boo boo during setup. Most of my bridges report Moat as the mechanism. Just trying to learn something. Best, potlatch Sent with [ProtonMail](https://protonmail.com/) Secure Email.

Introduction from ellie (at) nicecock
by ellie＠nicecock.eu 14 Dec '21

14 Dec '21

Dear relay operators, I would like to take this opportunity to also introduce myself. Online, I most often go by the name Ellie. I have set up one relay so far, but plan to host one or two more in the coming days/weeks with more planned down the road. I am not even close to running the same number of nodes as some of you guys do, but I am just doing my part. All my nodes should be hosted under the tor.nicecock.eu domain. The domain originated as an acronym for a project I did with a couple of people. Unfortunately, it could not continue under that name. My eventual goal is to run somewhere around five to ten nodes. My current node is running on AS12876, which is quite a popular choice for nodes. I recognize this is not that good, but I figure running a node despite that is better than not running one at all. I am looking forward to talking and discussing with you in the future. Best regards in addition to a nice day, Ellie P.S. I hope I am not needlessly spamming the mailing list, I just wanted to introduce myself even as a small beginning operator.

Mitigating log4j exploits
by Jens Kubieziel 11 Dec '21

11 Dec '21

Hiho, we got a notice that currently several exploit attempts for the log4j flaw going through Tor exit nodes und using LDAP. See https://www.greynoise.io/viz/query/?gnql=tags%3A%22Apache%20Log4j%20RCE%20A… The sender asked to do something against the currently running attacks. One possibility is, in my opinion, rejecting connection over ports 389 and 636. What do you think? Should we as exit node operators block connections over those LDAP ports for some amount of time? Best, qbi

Responding to Tor censorship in Russia
by gus 11 Dec '21

11 Dec '21

Dear relay operators, Today the torproject.org was officially blocked in Russia. You can read more about the situation here[1]. Russia is the country with the second largest number of Tor users, with more than 300,000 daily users or 15% of all Tor users. As it seems this situation could quickly escalate to a country-wide Tor block, it's urgent that we respond to this censorship! We need your help NOW to keep Russians connected to Tor! We are calling on everyone to spin up a Tor bridge. If you've ever considered running a bridge, now is an excellent time to get started, as your help is urgently needed. You can find the requirements and instructions for starting a bridge in the Help Censored Users, Run a Tor Bridge blog post: https://blog.torproject.org/run-a-bridge-campaign/ Gus [1] https://blog.torproject.org/tor-censorship-in-russia/ https://gitlab.torproject.org/tpo/community/support/-/issues/40050 -- The Tor Project Community Team Lead

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

Is Tor Actually "Blocked" In Russia, or Are Some Users Unblocked for now?
by Neel Chauhan 06 Dec '21

06 Dec '21

Hi tor-relays@, While I don't live in Russia, nor are my parents from Russia (they're from India), today, I noticed these articles that some people noticed Tor is blocked in Russia (sorry for being late): https://ntc.party/t/ooni-reports-of-tor-blocking-in-certain-isps-since-2021… https://forum.torproject.net/t/tor-blocked-in-russia-how-to-circumvent-cens… Yet, when I look at Tor Relay Status, I noticed many relays hosted on Russian residential ISPs are still online, and only a few aren't: Moscow City Telephone: *https://metrics.torproject.org/rs.html#search/as:AS25513 Rostelecom: * https://metrics.torproject.org/rs.html#search/as:AS12389 * https://metrics.torproject.org/rs.html#search/as:AS42610 * https://metrics.torproject.org/rs.html#search/as:AS34168 Vimpelcom: * https://metrics.torproject.org/rs.html#search/as:AS8371 * https://metrics.torproject.org/rs.html#search/as:AS8402 MTS: * https://metrics.torproject.org/rs.html#search/as:AS60496 I didn't notice a big reduction in "relay" users on Metrics: https://metrics.torproject.org/userstats-relay-country.html?start=2021-09-0… But did see an increase in "bridge" users: https://metrics.torproject.org/userstats-bridge-country.html?start=2021-09-… And most Ooni results still show Tor can connect fine: https://explorer.ooni.org/search?until=2021-12-06&since=2021-11-29&probe_cc… I feel it could be possible it's one of the two: * Most likely, the censorship rollout is in stages. Some users are blocked but other's aren't, where it wasn't rolled out is still unblocked. * Less likely, but Russia found people could use pluggable transports, like HTTPS obfs4 bridges and maybe they found blocking Tor itself is ineffective, or trying to block "meek" users ended up blocking Microsoft and ASP.NET/Azure-based webapps. Disclaimer: I work at Microsoft, but not on Azure as of now. I did however interview for a position in the Azure umbrella (not on the CDN however). -Neel Chauhan

Recent rejection of relays
by Georg Koppen 02 Dec '21

02 Dec '21

Hello everyone! Some of you might have noticed that there is a visible drop of relays on our consensus-health website.[1] The reason for that is that we kicked roughly 600 non-exit relays out of the network yesterday. In fact, only a small fraction of them had the guard flag, so the vast majority were middle-only relays. We don't have any evidence that these relays were doing any attack, but there are attacks possible which relays could perform from the middle position. Therefore, we decided we'd remove those relays for our users' safety sake. While we were already tracking some of the relays for a while, a big chunk of them was also independently reported by a cypherpunk and nusenu helped analyzing the data. Thanks to both of them from our side. Foe what it is worth: a large part of those relays did not set any valid contact info and/or when we tried to contact some of the relays' operators the emails bounced. However, we sometimes need to have ways to reach relay operators, be it for debugging purposes or for helping them with relay misconfiguration. Thus, please set a valid contact info when running relays. Finally, anyone running relays: try to get connected to the community so we can build some trust among each other. That seems to be an essential part in our long-term strategy to fight bad relays trying to enter our network. Georg [1] https://consensus-health.torproject.org/graphs

Relays running an unsupported (EOL) Tor version
by Georg Koppen 01 Dec '21

01 Dec '21

Hello! Relays running unsupported Tor versions is a problem we have never really dealt with in a systematic way in the way. Some of you might recall that we (with the help of volunteers) tried back in 2019/2020 to get operators, running an unsupported Tor version, to upgrade[1] but then we dropped the ball. Alas. We just started that process again by contacting every relay operator running an outdated Tor version (any version not 0.3.5.x or 0.4.5.x or 0.4.6.x or 0.4.7.x) by email where possible. Additionally, we created a wiki page outlining the current process and things we still need to figure out.[2] On that page we plan to make statistics related to the EOL relay removal available as well, including the final list of relays we'll reject. Thus, stay tuned. Feedback, as always, is very much welcome! We plan to keep this topic on our radar this time while refining the process as we go. Meanwhile, if you are running a relay with an unsupported Tor version, please upgrade for the sake of our users' safety. If you need help, join us on #tor-relays or #tor-relays:matrix.org if you use Element. Thanks, Georg [1] https://blog.torproject.org/removing-end-life-relays-network [2] https://gitlab.torproject.org/tpo/network-health/team/-/wikis/Relay-EOL-pol…

Mystery with Exitnode 4273E6D162ED2717A1CF4207A254004CD3F5307B (176.10.99.200)
by Tschador 23 Nov '21

23 Nov '21

Hi, in the last few days I noticed a curiosity with the Exitnode 4273E6D162ED2717A1CF4207A254004CD3F5307B: Every time I call 'https://www.startpage.com', the URL in the Browser changes to 'http://localhost/'. Other browser: same effect. Other sites - no problem. Other Exitnodes - no problem with 'https://www.startpage.com' and other sites. What's going on there …? Regards

Massive CPU load on high capacity guard node
by failing.flyaway443＠mailer.me 20 Nov '21

20 Nov '21

Hello Everybody, my relay is now almost two weeks old and has the following flags: Fast, Guard, Running, Stable, V2Dir, Valid. I lost the HSDir flag because I had to restart the Tor process, my downtime was just a few seconds, maybe that's why I kept the Guard flag. I was expecting a drop in traffic when I got the Guard flag (as mentioned in the FAQ), but the opposite happened. At the moment there are around 15000 active connections, over 11000 inbound and just 4000 outbound. I looked at the connections in Nyx, and it seems that my relay is indeed used as a Guard node (most of the IPs are "scrubbed" and the outgoing connections are to middle nodes). Before I got the Guard flag, I had around 5000 connections at the same time and was relaying traffic at peaks of 55MB/s. My server is connected to a Gigabit link. It's not a regular VPS, I have a dedicated CPU with two cores and dedicated 8GB RAM. Traffic is unlimited. The problem is that I'm now relaying traffic at ~25MB/s, and whenever there are spikes of over 30MB/s the CPU load on both cores (!) is very high. I'm still moving ~5TB per day, that's a lot, I know. But there would be even more possible with the internet connection of my server. My Server has two dedicated CPU cores of an AMD EPYC 7702, but unfortunately I only get the base frequency of 2GHz inside the VM, not the boost frequency of 3,35GHz (misleading information on the hoster's website). I could relay way more traffic if there wouldn't be this issue with the CPU load. This is the bottleneck, the 1Gbit link is guaranteed. I read in the FAQ that a modern CPU with hardware acceleration is able to relay traffic @~500Mbit in both directions. The EPYC 7702 supports AES-NI. I checked this, it is activated in my VM. I'm running Debian 11 Bullseye and tweaked the networking capabilities with some instructions I found from torservers.net (mnostly sysctl.conf tweaks) There is no additional software installed that uses lots of ressources, just a few tools. Here is a screenshot of Glances during a traffic peak (I set the Tor process to +10 on purpose): https://i.ibb.co/8brmZkf/glances.png The average CPU load is ~1.50, this is still ok for a dual core, but it should stay below 2.0 (at least it should not go above 2.0 for more than a few minutes). Does anyone here have an idea what I could do? Since the load on both cores is pretty high, I don't think it makes much sense to set up a second relay on the same server. Of course I could throttle the traffic, but is there anything else I can do? I rented this rather expensive server to help the Tor network with a really fast Guard node... Thank you everyone for your time and responses! Have a great weekend! Best Regards, Elias

relayor v21.2.0-rc is released: prometheus exporter support
by nusenu 19 Nov '21

19 Nov '21

Hi, relayor v21.2.0-rc is released. relayor is an ansible role that helps you with running tor relays with minimal effort (automate everything). https://github.com/nusenu/ansible-relayor#main-benefits-for-a-tor-relay-ope… NOTE: This release contains a backwards incompatible change, if you upgrade from an older release please read the upgrade guide before upgrading. https://github.com/nusenu/ansible-relayor/wiki/Upgrade-Guide-from-version-2… This version of relayor uses MetricsPort (when enabled) via TCP on 127.0.0.1. This is less safe then using unix sockets because all processes on the system get access to tor's prometheus metrics since there is no authentication supported. When MetricsPort gets unix socket support, relayor will switch to that safer option. https://gitlab.torproject.org/tpo/core/tor/-/issues/40192 Changes since relayor v21.1.0: * major new features: * add support for tor's prometheus exporter (MetricsPort) * this is a relayor beta feature requiring tor >=0.4.7.2-alpha) #217 * generates prometheus scrape, nginx reverse and htpasswd config files on the control node for easy copy paste into your prometheus/nginx configuration * every tor instance gets an id label (IPv4_ORPort) * support arbitrary torrc options #192 * fix broken debian tag - reported by @jn9999 #224 * fix broken link - PR by @jn9999 #223 * README: * make clear that we do not remove previously managed tor instances on config change - reported by @tsekityam * update OfflineMasterKeys link * make apt update_cache configurable * drop support for Debian 9 * increase min. ansible version 2.9.23 -> 2.9.27 kind regards, nusenu -- https://nusenu.github.io

Loss of Stable flag
by Arlen Yaroslav 16 Nov '21

16 Nov '21

Hello to all relay operators! My relay Deepsky (09A70E396DE93F54D4541BBB0EC8E2B23761F34F) has not been receiving the 'Stable' flag from the DA consensus. Up until recently (the past month or so) it had been assigned the full complement of flags. Nothing has been changed on the server and I am not aware of any issues. Would any of the directory authority operators be able to shed light on why some of the DAs are not assigning it the flag? Thanks!
