Good evening, I'd like to ask: How would one go about encouraging an organization (such as a college, university or library), that they are affiliated with to some extent, to operate a Tor Exit Relay? I currently operate a Non-Exit relay at home, but I would like to also see if me and some others in my organization could start an exit relay as well (Our jurisdiction is the United Kingdom). Thank you for reading, allforprivacy operator.

OpenBSD -stable net/tor and 0.4.7.7
by George 10 May '22

10 May '22

The OpenBSD net/tor -current port is correctly on 0.4.7.7, but the -stable port is still on 0.4.6.10. I submitted a diff to update -stable port to 0.4.7.7 last week, but it has not been committed yet. https://marc.info/?l=openbsd-ports&m=165179875418235&w=2 It's attached and should work fine. In order to update the OpenBSD -stable port you need an updated -stable 7.1 ports tree, then you apply the patch within the /usr/ports/net/tor port, and build from there. I can provide more guidance if necessary, but in order to not bore everyone else, maybe the Tor-BSD list is more appropriate? https://lists.nycbug.org:8443/mailman/listinfo/tor-bsd I can send out an amd64 -stable package, but then you'd have to trust me. g

Bridge not used

Hi Tor-Operators, I have installed a bridge according to the official how-to. The config is as follows: Log notice file /var/log/tor/notices.log DataDirectory /var/lib/tor Address bridge.xxx.de BridgeRelay 1 ORPort 1044 ServerTransportPlugin obfs4 exec /usr/bin/obfs4proxy ServerTransportListenAddr obfs4 0.0.0.0:9043 ExtORPort auto ContactInfo arnimw(a)mailbox.org Nickname lunabridge PublishServerDescriptor 1 BridgeDistribution any Under https://metrics.torproject.org/rs.html#details/4DD98FB1959065309FD4A183530B… I see basically no usage, the logs are fine - as far as I can tell. Any help appreciated! Best, Arnim

Tor 0.4.7.7 Segmentation fault on Ubuntu 22.04 caused by "rseq"
by Xiaoqi Chen (Danny) 07 May '22

07 May '22

Dear relay operators, I recently upgraded one of my relays to Ubuntu 22.04 and now tor keeps crashing. I debugged a little bit and saw the following error in the log. It appears that it's due to seccomp not allowing "rseq" syscall, and possibly related to the latest version of Glibc. I temporarily mitigated the issue by turning off sandbox mode (remove "Sandbox 1" in torrc). Does anyone know how to properly resolve the crashing issue?

Tor Exit: Complaints of IP being used for "spam" despite exit policy
by Neel Chauhan 05 May '22

05 May '22

Hi, A day or two ago, my Tor exit host, Psychz Networks, has sent me complaints about my IPs being used to send "spam" despite me having blocked Port 25 (and 465/587) in the exit policy. Psychz threatened to block Port 25 even when my exit policy explicitly blocks 25/465/587. The URLs I got were from Cisco Talos: * https://talosintelligence.com/reputation_center/lookup?search=104.149.136.2… * https://talosintelligence.com/reputation_center/lookup?search=104.149.133.5… Sometimes I think "is my FreeBSD exploited and being used to send spam", but then I also see Linux relays on other ISPs also on the blocklists. Yes, I am aware Tor exit relays will land on blacklists. But getting complaints from spam is new, especially when my relays are blocking SMTP. I am worried I would have to find a new host if they continue complaining. Darn, Psychz has been one of the more reliable exit hosts (on-and-off) for many years, although they are more vigilant on abuse than say BuyVM. BuyVM is similarly priced (although my Psychz is an special offer) and solid but has too many exits. OVH and TerraHost only allow exits on much more expensive dedicated servers. Prgmr and HostMaze allow exits but has so-so peering. I just hope Psychz doesn't continue to complain. -Neel

BSD tor ports/packages and impending 0.4.7.7 release
by George 03 May '22

03 May '22

BSD relay operators, like everyone else, should be aware that upgrading tor to 0.4.7.7 is critical for exit relays. The source is available now at: https://dist.torproject.org/tor-0.4.7.7.tar.gz Specifically for the BSD ports, here is the current status and workings. Any corrections appreciated. * DragonflyBSD https://github.com/DragonFlyBSD/DPorts/tree/master/security/tor Downstreams from FreeBSD quarterly updates, so may not have a 0.4.7.7 package or port for security/tor until July. * FreeBSD https://www.freshports.org/security/tor https://cgit.freebsd.org/ports/tree/security/tor https://svnweb.freebsd.org/ports/head/security/tor/ Updated to 0.4.7.7 already, and can be installed from security/tor now. Working fine at this point. For pkg(8) users, ensure that /etc/pkg/FreeBSD.conf line 11 is set to "latest", as opposed to "quarterly", which should be the case regardless of this security/tor release: url: "pkg+http://pkg.FreeBSD.org/${ABI}/latest", * NetBSD https://pkgsrc.se/net/tor pkgsrc's current port of net/tor was updated to 0.4.7.7. The stable port is still on 0.4.6.10 at https://cdn.netbsd.org/pub/pkgsrc/stable/pkgsrc/net/tor/Makefile * OpenBSD https://cvsweb.openbsd.org/cgi-bin/cvsweb/ports/net/tor/ The -current net/tor has been updated to 0.4.7.7 and the package is available. For users running 7.1-stable, net/tor 0.4.7.7 will hopefully be officially backported. Users can also update net/tor from ports on -stable themselves easily enough. If you're not on 7.1-stable, consider upgrading immediately. Thanks. g

Possible Connection Storm

Checking my relays after being away for a few days, noticed that one of them was showing as Overloaded, which I've never seen in over a year's running.

Instabilities in Hydra family expected
by abuse-node49＠posteo.de 19 Apr '22

19 Apr '22

Hello network! I would like to briefly inform that I have repeated problems with the hoster Yourserver.se, where I run some exit relays. Again a relay was deactivated with the message "Botnet". At that time I wrote a detailed explanation about the issue. I agreed to a temporary switch to a harmless relay, but as an exit operator I did not want to keep this state. So starting today the "Hydra family" will get some gaps which will take some time to replace. I know that there is an attempt to write a list of recommended providers somewhere. However, I have found that some of the information is not up to date. It is better to look into the Tor Metrics and find out the hoster for current exit relays that is mentioned there. Sometimes you are lucky. From my point of view, it should be possible to find out the age of exit relays from the Tor network database in relation to the hosters (ASxxxx) and thus find a ranking for reliability and suitability. Automatically, this would be a ranking for "privacy support". However, it would then be problematic that all newcomers would rely on these few hosters. Perhaps we will have to live with these problematic hosters and endure the dynamics. Here is a note about startup problems of the Tor service after a reboot: In my observation, this only happens with slow hardware and may also depend on the hypervisor. I use the same systems and configurations everywhere and see dead Tor services after startup only with the hoster Trabia.com and UDN (Ukrainian Data Network), with UDN working better now than a few years ago. It seems to be a timeout during start-up of the OS. With Debian "systemctl restart tor.service" solved the problem until the next reboot. With delayed start or a cron job this could be avoided, I assume. The fast hosters like * OVH.com, * Frantech.ca, * Flokinet.is, * Bahnhof.net * and Terrahost.com do not have the problem after reboot. First I will try to replace the failing VPS at Yourserver.se with reliable providers from my list, but I am checking other offers. I would also like to ask other participants in the network to name smaller, still unknown hosters. Kind regards Olaf

Tor Relay showing as down
by Alexandre Corradi Guerreiro 19 Apr '22

I have been running a ToR Relay for almost a year. https://metrics.torproject.org/rs.html#details/6C6C87A774A211F53DE5116A7A8A… and suddenly it stopped working. I don't see any errors on the logs but the relay is always showing in the relay search page as down. I even tried to upgrade the Tor client to a new version 0.4.6.10 to see if something changes, but no success. The process is running all the time, I see some circuit connections forming and after a while no more traffic going. Based on the syslog I see that everything looks fine, see next example.

Re: [tor-relays] Does Tor work with Intel QAT acceleration
by Andreas Bollhalder 12 Apr '22

12 Apr '22

Hello Alex Thank you for your nice hint ot QAT_Engine. Yes, in theory it really seems to be possible. Looking at the Github repo of the QAT_Engine, it looks like there are still some issues with OpenSSL 3.0: Support for QAT HW ECX, QAT SW ECX, QAT HW PRF and QAT HW HKDF is disabled when built against OpenSSL 3.0 due to known issues instead it uses non-accelerated implementation from OpenSSL.I'm on Ubuntu 20.04, so I should be still using OpenSSL 1.x. There are plans for switching to OpenSSL 3.0 in Ubuntu 22.04. We'll see... So, one really has to test and I need to think about it. Wouldn't be a cheep test, but if this platform can give me a medium power system (~50W) and great speed, then it's definitively what I'm looking for. Otherwise I would prefer a Ryzen like the 5750GE.

For my definitive Tor relay hardware, I'm currently researching some options, which would be capable of handling Tor traffic at the rate of 200 to 300MBytes. Even it would be used nowadays, but who knows whats coming in the future and I hope this relay would last 5 years ore so. > > It looks to me, that with a normal CPU, it's impossible to reach my goal. But then I encountered, that Intel has the Quick Assist Technoloy (QAT) integrated in some of their products (ie. Atom C3xx8). This QAT can be used with OpenSSL as a hardware accelerator for encryption. There also exist dedicated PCIe cards with QAT (ie. Netgate CPIC-8955). > > Searching the Internet, I couldn't find any information if QAT would be helpful with Tor. But Tor uses the OpenSSL library and this can use the QAT acceleration. Is there anyone who has tried this und can share his expirience? > > Thanks in advance > Andreas > _______________________________________________ > tor-relays mailing list > tor-relays(a)lists.torproject.org > https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-relays > In theory, you should be able to enable QAT with "HardwareAccel 1" on OpenSSL 1.x after installing https://github.com/intel/QAT_Engine. I'm not sure about the process for OpenSSL 3.0; I believe it involves editing OPENSSLDIR/openssl.cnf.

I was setting up exit nodes and I had a question. Why is it recommended to use DNS caching software Unbound? What benefits does it provide compared to using hoster's DNS resolver?
