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

Tor-node/relay: System installation vs. TorBrowser
by Lars Edman ＠ LinuxSuSE 17 Mar '15

17 Mar '15

Hi! I was referred to you from help(a)rt.torproject.org. when asking them if they discouraged from using tor as a client or node/relay with tor in a system installation. By "system installation" I mean installation of tor, libevent, libgeoip (and ev vidalia) together with openssl. I found they today absolutely discouraged from the use of such a "system installation" when using tor as a client. When it came to using tor as a node/relay or running a server they referred the question to you. My reason for asking is that I have been running a "system installed" tor node in my Slackware server for 3 years now. subsequently updating/grading them. It has served well and I monitor the log continously for warnings or errors correcting the when they very rarely occur (usually by updating/_grading). My reason for using a system installation for node/server use is that I've found it easier to configure the way I wanted than the BrowserBundle. Do you consider this kind of installation insecure? Best regards Larse

List of longest lived Exits and Relays
by grarpamp 17 Mar '15

17 Mar '15

Is there a list somewhere (preferably on metrics) of exits and relays sorted by longest period of service (years) on the same IP? Preferably this would subset by exit policy... whether open, or using some published, named, and adopted "standard" exit policy. Such as "reduced" (whatever that means, each version should be reflected in the name "reduced-N").

Hey, I have connection problems with my relay. Can someone tell whats this mean: Mar 16 23:59:12.000 [debug] TLS error: unexpected close while reading (SSL negotiation finished successfully) Mar 16 23:59:12.000 [debug] channel_close_for_error(): Closing channel 0x7fe72b1a41c0 due to lower-layer error Mar 16 23:59:12.000 [debug] channel_change_state(): Changing state of channel 0x7fe72b1a41c0 (global ID 79) from "closing" to "channel error" I get a lot of these news.

Many inbound and outbound connections but no circuits
by mattia 16 Mar '15

16 Mar '15

Hello, I've been running a relay for some weeks. It has now earned the stable flag. Despite this I always have more than 500 inbound and outbound connections but no circuits at all. Is this normal?
