torservers.net: some exits became guards? (deanonymization risk)
by nusenu 15 Jun '17

15 Jun '17

Dear Torservers, are you aware that you have recently become a relay operator with end-to-end correlation (deanonymization) capabilities? (in fact you are the biggest known such operator) This is especially bad for tor clients because you are also one of the biggest tor exit operators. Some of your relays which used to be exits recently became guard-ony relays. https://nusenu.github.io/OrNetStats/endtoend-correlation-groups#httpswwwtor… Is there anything I can help you with to fix this and reduce the risk for tor clients? thanks, nusenu -- https://mastodon.social/@nusenu https://twitter.com/nusenu_

IP space for Tor exits - any takers?
by Moritz Bartl 12 Jun '17

12 Jun '17

Hi, After some trouble and ongoing discussions with one of our IP providers, we're again toying with the idea of registering IP space with RIPE ourselves. We can apply for a /22, which can be split into four /24s and announced at different locations (254 addresses each). Until now, we tried to avoid that, because we don't have enough "other things" to put on the same netblocks, so basically "one exit" would waste 254 precious IPv4 addresses (the full /24 address block needs to be announced from one location). But lately, with the rising amount not of abuse but of automated notifications and scared ISPs, and with the sponsoring of up to 10GE by Community-IX, we would really like at least one /24. Gareth from Brasshorn has graciously offered a spare /24 of his. The alternative would be that we apply for our own IP space, which would in turn mean that we could supply three other organizations with a /24 for their exit(s), or bridges. For bridges it is actually not that crazy, even if the range is "known" and easy to find: Most censors won't auto-detect them easily, and even if some do, the bridges are still valuable in many other locations. Also, this would allow for a bit of experimenting with tarpitting, different decoy strategies, etc. In terms of WHOIS information, the /24 can be segregated further, so an option would be to use a location where you have other uses for larger number of IP addresses. If you like the idea, and have actual use for a /24, please contact me off-list and explain what exactly you would like to do with it. If we have three other organizations (or reliable individuals) and a couple of good use cases, we're willing to apply for the /22. -- Moritz Bartl https://www.torservers.net/

Another relay is using the same name as mine.
by Alan 11 Jun '17

11 Jun '17

I just need some advice. I'm running 3 relays, one is called Andromeda. Today I find out there is another relay called Andromeda. https://atlas.torproject.org/#search/Andromeda mine is running from ip 144.217.161.119 Is it a problem with relays using the same name? Should I contact them and inform them of their error? Should I just leave it? Any advice would be very helpful. Alan.

published descriptor missing from consensus
by Scott Bennett 09 Jun '17

09 Jun '17

This time I'm stumped. I confess I have not followed this list for a long time until the last few days, so it's possible that I've run afoul of something already discussed. Late Wednesday afternoon, I restarted my relay (MYCROFTsOtherChild), which changed it from 0.3.0.6 to 0.3.0.7. That was the only change I made. It went through a normal startup and published its descriptor. After a few hours, tor noticed that its descriptor was still not in the latest consensus, so it republished it. After several more hours had passed with each consensus lacking my relay's descriptor, I made a small change to an ExitPolicy line in torrc. In the meantime, I had read some recent postings to this list and had noted some remarks regarding mismatched RSA and ED25519 keys, so I renamed /var/db/tor/keys and restarted tor again, whereupon it generated new keys and appeared to proceed normally. Once again a new descriptor was published and has since been republished and updated with no apparent problem beyond some republications being told by one or more authorities that the descriptor was rejected as "not new". Nevertheless, my relay's descriptor still has not appeared in a consensus since the last time it ran 0.3.0.6. If an authority operator would be so kind as to check the authority's logs for any errors pertaining to my relay with either its old keys or its new keys and let me know what they say, I would be grateful. Thanks for any help or suggestions of things to try. Scott Bennett, Comm.

Hi everybody Can somebody please help me understand the change log for 3.1.x: "Support for these algorithms requires that tor is built with the libzstd and/or liblzma libraries available." Is it AND or OR or something whatever different ? Might ports archivers/zstd only do the job (OR-type): Tor 0.3.1.2-alpha (git-61625b8f26384a4a) running on FreeBSD with Libevent 2.1.8-stable, OpenSSL LibreSSL 2.5.3, Zlib 1.2.8, Liblzma N/A, and Libzstd 1.2.0 -- (And why says the notice message "OpenSSL LibreSSL" ?)

Who is running the two biggest Exits in the network?
by Paul 01 Jun '17

01 Jun '17

Since about mid April there are just two similar Exits making up now about 4.5% exit probability together. Located in Panama, run in the okservers.net network, AS395978 ,they don’t give up any further information about themselves. Personally I would feel better at least having a contact or even better, knowing who is giving that much effort. Probably a MyFamily configuration should be placed as well? https://atlas.torproject.org/#details/29C92C854E0F6652A77F3A8B231D693299396… https://atlas.torproject.org/#details/2CA4B2F36C2DDECFCB0B5A0D3300ED30E68E2… Paul

This feature is interesting and I did not know about it. However, I have been reading the documentation page[1] and I have the impression that the more I read the less I understand how it works. If I look inside the DataDir of one of my relays - a standard Debian install - see this: ``` ed25519_master_id_public_key ed25519_master_id_secret_key ed25519_signing_cert ed25519_signing_secret_key secret_id_key secret_onion_key secret_onion_key_ntor secret_onion_key_ntor.old secret_onion_key.old ``` So, here some of the things I think I have understood: * Tor uses a ed25519 key to generate the other keys need to decrypt incoming traffic and route it to its next destination on the network. I don't know how this works in practice, but probably it is too much detail at the moment. * In the standard install the master key is the `ed25519_master_id_secret_key` above, which has no passphrase. * If in `torrc` we declare `OfflineMasterKey 1` then the `ed25519_master_id_secret_key` will not reside anymore on the relay but on a separate machine. * In the process of generating the master key (with the command `tor --keygen`, all the files above will be generated. * To run the node with `OfflineMasterKey 1` you need to copy all the files generated in the previous step *with the exception of the master key*. I had also a few questions: * is the above correct? * if I use the offline master key protected with a passphrase will I need to input the passphrase every time I restart Tor (I have in mind what Apache does when you restart it and have certificates protected with a passphrase)? * Assuming that I am going to use a separate machine to generate the master key I need to make sure that the version of Tor on the machine that I use to generate the key and the relay?

reminder: tor 0.3.1.1-alpha is _not_ recommended (known bug)

Since there were only 8 relays running 0.3.1.1-alpha I didn't bother to state this here, but since the number is rising since yesterday I just wanted to remind you that tor 0.3.1.1-alpha contains a bug that makes this not a good version to use.

Question about circuit/path live time
by Olaf Grimm 31 May '17

31 May '17

Dear readers ! For my relays I looking for a torrc parameter to reduce the circuit live time from default of 10 minutes to about 5 minutes. My intension: I dont' know is the point of time to switch the path between relays synchronized. An overlap (or different switching time) will reduce the path live time to less than 10 minutes. This is ok for me, because the circuit analysis time for attackers is less than 10 minutes (traceroute...). Synchronized relays keeps a whole circuit path open for 10 minutes, from guard to the exit. Am I right? Am I right with my intension to change the default circuit live time or is this not necessary? A short answer would be ok. Assuming torrc parameter: MaxCircuitDirtiness NUM (Default: 10 minutes) The backgroud of the story (and why I want to generate more noise): Last year, on July 19, my exit relay was seized at home. I knew about the danger, but I ignored it. According to the police, my relay was abused for about 5 months, again with the same (evil) web server as the target. I am assuming my Exit Relay was explicitly selected as an exit. To protect the relay operators, you might want to remove this function. A targeted compromising of an operator must not be possible. The police photographed some of the current connections displayed with ARM. A test with ARM showed an indication of a seemingly complete circuit from the guard to the exit. I see Source -> Target, Guard, Middle, Exit. I'm not sure, but I get a bad feeling. Please tell me that my interpretation of the displayed content in ARM is wrong. For the time being, I only have 2 Middle nodes as VPS online. Later, after the completion of the law procedure, I switch the two VPS middle nodes back to Exit Relays (Provider Keyweb and FlokiNET). The third middle node at home remains only a middle node. I swear this. Best regards! Olaf (node49/node49a/node49b)

Neldoreth relay seized ?

Dear Neldoreth relay’s operator, This day, we were informed of a Tor node seizure at FirstHeberg during the 13-14/05, related to Wanacry infection of the french company Renault. https://www.nextinpact.com/news/104398-wannacrypt-nud-tor-saisi-chez-firsth… FirstHeberg say the seized node was "traffic analyzed" during some times before being shuting down for content cloning and drive given to cops. They are at least 5 others relays seized under the same case at OVH and Online providers. https://www.nextinpact.com/news/104302-wannacrypt-nuds-tor-saisis-par-autor… https://gist.github.com/nusenu/3d7bbeb7c97af591d65003b4bfe70021/ After consensus investigation, it seems your Neldoreth node is the only hosted at FirstHeberg with a downtime during this timeframe (from 14/05 18:00 to 17/05 14:00). This node is currently running, but lost its guard flag since restart. Could you confirm if your node was seized or not ? If seizure confirmed or suspected, your private key is probably no more safe, so please report your fingerprint to bad-relays(a)lists.torproject.org for blacklisting to avoid reusage, and renew your private key.

New exit node best practices
by Isaac Grover, Aileron I.T. 29 May '17

29 May '17

Good evening, After many months of running a relay, I'm planning to establish up a family of exit nodes with geographically diverse VPS providers, shying away from the list of the most heavily used Tor friendly providers. Several questions: - Does establishing a family increase the risk of the nodes being taken down en masse? - Do you suggest providing ample contact information for the node directory, as opposed to little or none? - I'm being very upfront with sales@ regarding my purpose before signing up, and making sure they're okay with it. What questions should I be asking to be sure they'll be Tor friendly before shutting down my exit nodes? Make your day great, Isaac Grover, Senior I.T. Consultant Aileron I.T. - "Practical & Proactive I.T. Solutions" O: 715-377-0440, F:715-690-1029, W: www.aileronit.com

Memory Problems with tor releay
by tor-relay.dirk＠o.banes.ch 27 May '17

27 May '17

Dear all, we are operating two exit nodes with each two tor processes out of Switzerland. The nodes worked quite stable until about 2-3 weeks ago. Since then we experience frequent disruptions (Up to several times a day). This is caused by a significant rise in memory consumption by the tor processes and ends with a tor process being killed by the Linux Kernel: May 22 00:30:43 tor2 kernel: [2257156.134100] Killed process 40964 (tor) total-vm:448088kB, anon-rss:0kB, file-rss:0kB The systems are physical machines with Ubuntu 14.04.5 LTS with 4 GB of memory. This was sufficient the last 2 years. For more details a sample of this behavior is documented in a Ticket [1]. Tor project team is researching but until now no hints lead to an improvement. Due to a tweet last week [2] and the follow up discussion with another operator I became suspicious that is not just just us having a problem rather it cloud be more common. Therefore here the question to you all - do you experience some strange behavior like described in the ticket as well ? Please let me know if so. If not - maybe it is just an unfortunate coincidence and we will end up make a clean install of both server hoping the problem will go away. best regards Dirk [1] https://trac.torproject.org/projects/tor/ticket/22255 [2]https://twitter.com/FrennVunDerEnn/status/864583496072876034

exit relay consensus weight
by Arisbe 26 May '17

26 May '17

Hello relay ops, I just made an interesting observation that I thought I would share. Yesterday I started a VPS exit relay at a well known hosting company in Moldova [0]. Within 24 hours I saw the consensus weight exceed 10000. The relay is bandwidth limited to 10 MiB/s. Not that I'm complaining! So it begs the question: Is there not enough exit relays on the Tor network? Arisbe [0] B06F093A3D4DFAD3E923F4F28A74901BD4F74EB1

If poor odds or afraid of such things, the farther distant and / or opposite legally, politically, logically and physically the better. > What happens if an operator themselves is anonymous? They lose the remaining hosting contract worth of bitcoin, get the account / card canceled, nym blacklisted, etc. For only running an exit / relay and nothing else... Policy / nuisance shutdowns by the hoster do happen often, nodes just move and redeployed elsewhere. Detainer for questioning, are rare, oops, you're free to go. Raids and confiscation, are rare, and property seems to be returned. Actual arrests / night in jail / charges, are even rarer, oops you're free to go. Charges that go to court, are extremely rare. Probably no one has *ever* been convicted that we know of? Because only running an exit / relay and nothing else, seems to be legal everywhere. (If it is illegal somewhere, then the operator is at fault for breaking that law.) And traffic passing through relays seems to have "ISP style" legal exceptions everywhere, that even cover "torts", so long as operators are not in business of inspecting or moderating. Which is why everything above is marked "rare". If you know of places where... a) relays themselves are illegal or b) ISP style exceptions do not exist ... you should definitely reply with such a list. Real problems are rare, and running relays is fun :) Legal environments typically apply equally so once you know your environment you can always add other overlay networks / services / nodes into to the mix if you're bored or have unused bandwidth in your contract: I2P, CJDNS, GNUNet, Freenet, Pond, VPNGate, XMPP / IRC, Remailers, Crypto Currencies, IPFS, etc...

I am running the relays on VPS providers so, I can choose (only) among the versions of Debian that are provided by the services as templates. When Stretch is release I will see if they make it available, in a reasonable time. I am settled anyhow to upgrade the nodes as soon as the new Debian version is released and I have a question. I have read that I can move the node keys when upgrading[1] and I will do that. One thing that will change with a fresh install is the IP address of the nodes. So, I was wondering, in general is a good thing to keep the same IP or changing it? Because in any case, I could try and do a dist-upgrade[2] so that I keep the old IP. I have also discovered now that DigitalOcean, one of the providers I use, provides a kernel-management interface[3] that could make the process easier. So, which is preferable between the two processes where one has the advantage of keeping the same IP (dist-upgrade) and the other not (fresh install)? Of course, I am assuming that I will be able to complete any of the two processes successfully.

Problem starting 0.3.0.7 on Ubuntu?
by Alexander Dietrich 23 May '17

23 May '17

Hello, did anyone else run into a problem when upgrading from 0.2.9.10 to 0.3.0.7 on Ubuntu? Tor is no longer starting, with these messages in syslog: [notice] Read configuration file "/usr/share/tor/tor-service-defaults-torrc". [notice] Read configuration file "/etc/tor/torrc". [warn] Directory /var/lib/tor/SERVICE_NAME/ cannot be read: Permission denied [warn] Checking service directory /var/lib/tor/SERVICE_NAME/ failed. [warn] Failed to parse/validate config: Failed to configure rendezvous options. See logs for details. [err] Reading config failed--see warnings above. The permissions on /var/lib/tor/SERVICE_NAME/ are "rwx--S---" and it's owned by debian-tor, which worked for 0.2.9.10. Thanks, Alexander -- PGP Key: https://dietrich.cx/pgp | 0x52FA4EE1722D54EB

(FWD) [tor-announce] Tor 0.3.0.7 is released, with a medium security fix for relays

For those of you who are not on tor-announce... now would be a good time to remember to subscribe to tor-announce. :) --Roger ----- Forwarded message from Nick Mathewson <nickm(a)torproject.org> ----- Date: Mon, 15 May 2017 18:57:59 -0400 From: Nick Mathewson <nickm(a)torproject.org> To: tor-announce(a)lists.torproject.org Subject: [tor-announce] Tor 0.3.0.7 is released, with a medium security fix for relays Hi, all! There's a new Tor release (0.3.0.7) available on the website. It fixes a bug affecting relays running earlier versions of 0.3.0.x that could allow attackers to trigger an assertion failure on those relays. Clients are not affected; neither are relays running versions before 0.3.0.x. If you're running a relay with one of the affected versions, you should upgrade. Source is available on the website now; packages should be available over the next several days. =========== Changes in version 0.3.0.7 - 2017-05-15 Tor 0.3.0.7 fixes a medium-severity security bug in earlier versions of Tor 0.3.0.x, where an attacker could cause a Tor relay process to exit. Relays running earlier versions of Tor 0.3.0.x should upgrade; clients are not affected. o Major bugfixes (hidden service directory, security): - Fix an assertion failure in the hidden service directory code, which could be used by an attacker to remotely cause a Tor relay process to exit. Relays running earlier versions of Tor 0.3.0.x should upgrade. should upgrade. This security issue is tracked as TROVE-2017-002. Fixes bug 22246; bugfix on 0.3.0.1-alpha. o Minor features: - Update geoip and geoip6 to the May 2 2017 Maxmind GeoLite2 Country database. o Minor features (future-proofing): - Tor no longer refuses to download microdescriptors or descriptors if they are listed as "published in the future". This change will eventually allow us to stop listing meaningful "published" dates in microdescriptor consensuses, and thereby allow us to reduce the resources required to download consensus diffs by over 50%. Implements part of ticket 21642; implements part of proposal 275. o Minor bugfixes (Linux seccomp2 sandbox): - The getpid() system call is now permitted under the Linux seccomp2 sandbox, to avoid crashing with versions of OpenSSL (and other libraries) that attempt to learn the process's PID by using the syscall rather than the VDSO code. Fixes bug 21943; bugfix on 0.2.5.1-alpha. _______________________________________________ tor-announce mailing list tor-announce(a)lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-announce ----- End forwarded message -----
