Tor-Tshirts
by Nchinda Nchinda 24 Mar '15

24 Mar '15

Is there still someone at Tor Weather managing tshirt distribution? I've been running a two fairly large relays for a couple months, although I also wouldn't mind paying for an official tor shirt. My email to Tor Weather went unanswered. https://atlas.torproject.org/#details/C1CFB375BED9D7506569E07B01753BC67EE87… https://atlas.torproject.org/#details/CAB78BF9BD73536DCB55E5BC98D5F3AAB45CF… Nchinda^2 -0.1743*kg^6 m^4 mol s^-14 Computer Scientist the light flares at this node

Help finding relay bottleneck
by James Murphy 24 Mar '15

24 Mar '15

I'm running the relay https://globe.torproject.org/#/relay/18EAAF7CB6C2ABE8583841D305C06A509F8C1C… and am getting substantially lower rates than expected after almost 3 months. I'm on a 1Gbps down/1Gbps up line but my middle relay is just barely creeping upwards of 5Mbps. This is NOT a problem of less bandwidth after receiving the guard flag, and I have read the lifecycle of a new relay documentation. I cannot find the bottleneck in my setup and was wondering if there are any good tools I could use to find where it is. I've read https://www.torservers.net/wiki/setup/server and https://wiki.archlinux.org/index.php/tor for tips on speeding things up, but nothing has proven successful. Things I have considered: CPU usage: hovers around 5-10%, using NumCPUs 2 Mem usage: 195 MB (10%), using DisableAllSwap 1 Using AvoidDiskWrites 1 to avoid SSD stress Rate/Burst limits at 20MB (160mbps) Using dd if=/dev/urandom of=rand bs=64M count=16 iflag=fullblock to create a 1GB file I test copying this file to/from another machine on my LAN using scp 100% 1024MB 28.4MB/s 00:36 to copy to the relay (307 Mbps) 100% 1024MB 53.9MB/s 00:19 to download from the relay (431.2 Mbps) Okay so not full 1Gbps speeds, but still an order of magnitude higher than the 5Mbps my relay is using, so the problem doesn't look like it is the router or gigabit switch on my LAN. I've also raised the maximum number of open file descriptors for the debian-tor user. In /etc/security/limits.conf I added debian-tor soft nofile 65000 debian-tor hard nofile 65000 I'm not sure if this worked because (even after reboot) sudo -u debian-tor bash ulimit -Hn returns 4096. I would say that is the problem, but looking in /proc/torPID/fd and doing ls -l | wc -l returns 1591, so I'm not hitting the limit of 4096. In any case, if you know why my limits.conf doesn't appear to have taken effect, let me know. I've also added other optimizations from the torservers wiki. My /etc/sysctl.conf is http://paste.debian.net/162765/ Thanks for the help, James Murphy

Ideas for the further development of TorServers
by Jens Kubieziel 23 Mar '15

23 Mar '15

Hi, during our relay operators meeting in Valencia as well as in IRC/XMPP we were discussing the future way of TorServers. Some of you had some good ideas and I started to put them into a list. TorServers will try to apply for funding this year as our current funding will expire or has expired. So we plan to integrate some or all of the ideas into our application and help you as relay operators. The current version of the list is at <URL:https://pad.systemli.org/p/ukMTrpwf6Yzv>. I'll add some more text in the next days. Feel free to add some comments, ideas, wishes etc. -- Jens Kubieziel http://www.kubieziel.de Ich würde gern leben wie ein armer Mann mit einem Haufen Geld.

Re: [tor-relays] Tor Cloud/AWS relay set up but no Tor installed
by SiNA Rabbani 22 Mar '15

Hi allicoder, The images on Tor Cloud website have not been updated for a while. The project is lacking someone that can keep it up to date. I tried to take on the responsibility but so far I have failed to dedicate the necessary time. Sorry for the bad experience. As far as the specific problem with the Cloud image itself, there is a script that is supposed to install the relay on first boot. See /etc/rc.local. You can also find that script here: https://gitweb.torproject.org/tor-cloud.git/plain/ec2-prep.sh There are a couple of issues with the script itself that I noticed immediately: 1) the harcoded pgp key is expired 2) the debian experimental repository is returning a 404 W: Failed to fetch http://deb.torproject.org/torproject.org/dists/experimental-precise/main/bi… 404 Not Found [IP: 38.229.72.16 80] If you wish to do some trouble-shooting, try to get these commands to run without any errors: sudo apt-get -y update sudo apt-get -y upgrade sudo bash /etc/ec2-prep.sh bridge Finally, now that you have a running image and ssh access, you can just follow the Tor relay installations here: https://www.torproject.org/docs/debian.html.en I apologize for the inconvenience and thank you for running a relay.

Tor Cloud/AWS relay set up but no Tor installed
by aredocilla＠gmail.com 22 Mar '15

Hello, I've been trying to set up a tor relay on AWS using the free tier using the instructions in various places (e.g. https://cloud.torproject.org/, https://www.fak3r.com/2012/08/11/howto-run-a-tor-node-in-the-cloud-for-free/). But sshing in from my PC shows clearly that not only is tor not running, it's not even installed! ubuntu@ip-172-31-28-207:~$ aptitude show tor Package: tor State: not installed Version: 0.2.5.11-1~precise+1 Priority: optional Section: net ... ubuntu@ip-172-31-28-207:~$ ps -ely | grep tor ubuntu@ip-172-31-28-207:~$ ls /var/log alternatives.log auth.log btmp dist-upgrade dmesg.0 dmesg.2.gz fsck landscape mail.err news udev unattended-upgrades wtmp apt boot.log cloud-init.log dmesg dmesg.1.gz dpkg.log kern.log lastlog mail.log syslog ufw.log upstart Has something changed, and the images no longer include tor on start-up (I made sure I followed the gist of the cloud.torproject.org steps, given that the interface has changed significantly; even went to the previous page from the linked one to check that the AMI thing mentioned tor)? I've noticed various people have posted online saying it's not safe to run Tor on cloud services - has the image been deleted because of this? I wanted to try it anyway because the main torproject website still says in several places that running a relay on AWS is A Good Thing. Or did I just do something wrong?

It would also help to know how much experience you have configuring hidden services. I'm sorry if I've pitched this at the wrong level, but I just want to start by making sure we have the same setup in mind when we talk about hidden services: Direct Connection: Client connects to [::1]:11001 client -[TCP/IPv?]-> server Hidden Service Connection: Client connects to foo...abc.onion:12345 via a local tor client socks proxy, which connects to a tor hidden service over onion routing, which connects to [::1]:11001 client -[socks/TCP/IPv?]-> tor client ---[onion routing/TCP/IPv4]---> tor hidden service -[TCP/IPv6]-> server Does your configuration match this? Can you answer the following questions about what you see? (It might help to answer them in order, stopping when you find the first error.) Configuration: - Are you using a testing, a private, or the public Tor network? - How is the hidden service configured? (please send us the hidden service torrc) Alternative Configurations: - What happens when you have the server listen on IPv4 rather than IPv6, and change the hidden service to connect to IPv4? - Can you connect to: -- Other hidden services on the same (globally routable) IP? -- Other hidden services in the same tor instance? Observed Behaviour: - Does the hidden service bootstrap fully, without errors? (arm and logs will help here) - What error do you get when you try to connect to the hidden service? -- Does the tor client fail to find a descriptor or introduction point for the hidden service? -- Does the hidden service tor instance refuse connections? -- Does the server refuse connections? -- Is the server accepting the connection but failing to respond? -- (You'll need to look in the client and hidden service logs to find out.) That should be more than enough :-) teor teor2345 at gmail dot com pgp 0xABFED1AC https://gist.github.com/teor2345/d033b8ce0a99adbc89c5 teor at blah dot im OTR C3C57B23 349825DE 929A1DEF C3531C25 A32287ED

Hello, Hi, I'm looking for some support with accessing a hidden service that is listening on [::1]:11001 I am able to connect to the listener locally but the hidden service doesn't seem to work. any ideas? The time on the machine is accurate and connections to other hidden services succeeds. Thanks, Manas

misconfigured advertised bandwidth? (rohan & theoden)
by Nusenu 19 Mar '15

19 Mar '15

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, first off, thanks for running tor relays! While playing around with compass.torproject.org I noticed your relays (theoden and rohan) because according to their advertised/observed bandwidth they are the fastest in the entire network: adv bw: rohan: 363.32 MB/s theoden: 191.44 MB/s but the graphs show different values: rohan: ~20MB/s theoden: ~10MB/s So I'm curious how come that their advertised/observed bw is so much higher.

Meeting notes of the relay operators meeting in Valencia
by Jens Kubieziel 17 Mar '15

17 Mar '15

Hi, below you find my notes for the relay operators meeting we had in Valencia. Those just some short notes. If you have any questions or remarks, please don't hesitate. * Introduction Several Tor relay operators met at Tor Developer meeting in Valencia, Spain. At our meeting we had operators from the following countries: - Germany - Netherlands - France - Spain - India - Costa Rica This document gives a short overview what we discussed. If you have any questions or comments don't hesitate. * DDoS attacks: One questions which was raised is what to do against DDoS attacks. Several ISPs complained about DDoS attacks against Tor relays. There were also shutdowns of servers. It was suggested to employ DDoS mitigation tools. Other operators suggested to don't do anything. It is better to educate the ISP about Tor. Do you have any experiences with this topic? * Abuse TorServers has templates for different cases of abuse. See [[https://www.torservers.net/wiki/abuse/templates]]. The Tor Project offers also some advice in their wiki. See [[https://trac.torproject.org/projects/tor/wiki/doc/TorAbuseTemplates]]. Furthermore several organisations developed their own templates. Someone at the meeting offered to review others templates. As a general advice one should start with thanking the person and acknowledge what they do. TODO: We should rephrase some of the templates and generate some hice, good example documents. * Bridges The current alpha release of Tor Browser Bundle 4.5 comes with support for obfs4. Currently there are only few bridges which use obfs4 and everyone is asked to enable the new protocol. Obfs3 doesn't really work in China and obfs4 is the current best bet. If you have any questions about obfs4 you should have a look at the documentation or write an email to Yawning (<yawning(a)torproject.org>). Some links: - How to run an obfs4 bridge: https://tor.stackexchange.com/q/6370/88 - Debian package: https://packages.debian.org/search?keywords=obfs4proxy - Post at tor-relays: https://lists.torproject.org/pipermail/tor-relays/2014-September/005372.html * Tor relays in Japan It is legal to run relays in Japan, but practically it depends on ISP. So if you know a person in Japan, encourage them to run a Tor relay. It was said that relays from SE asia went online for some time and slowed down the overall network. Jens talked to Mike Perry who couldn't remember such incident and also couldn't believe that this is true. * Relays in India There are some relays in India, some of them probably in universities and some very slow. A home connection is 60/60MB/s and capped at 8GB/80GB per month. I couldn't really understand what the correct numbers were. * How to make nodes faster Someone had a 10Gig which link was not used. It was recommended to use multiple processes; one process per core. So also hints at https://blog.torproject.org/blog/lifecycle-of-a-new-relay * Tor wheather Several peopel work on Tor weather. The status is not clear. However there is some need for a working version. * ARM devices We found out that several organisation have utilised some ARM device. Juris from Torservers runs a Bananapi at a data center and gets 30-40MB/s. DFRI has a router which they give away to interested persons. Jacob Appelbaum made a combination of Relay and Router. Merlijn suggested that Hardkernel has some faster ones which fit for exit relays. We want to work more closely together to create some neat device. * Stats on exits Someone asked if it is OK to run statistics on exit relays. As long as the tools only monitor the amount of traffic this is OK. Looking into exit traffic or even messing with the traffic would instantly qualify you as a bad exit. * Legal issues + Germany has no data retention law in place + data retention in the Netherlands: court case said illegal, try to make a law + France: https://netzpolitik.org/2015/franzoesischer-patriot-act-ueberwachungsmassna… (yes, data retention since 2011) + article 12 of ecommerce directive + Costa Rica has no data retention law * World Hosting Days + Who is interested to go there? * TODO - Work on templates - How many DMCA notices do you get? Can you give Jens some monthly numbers together with the exit probability of your relays? An EFF person wanted to collect some numbers. Jens will relay those numbers. - run obfs4 bridges -- Jens Kubieziel http://www.kubieziel.de
