Gigabit is powerful
by Felix 07 Mar '14

07 Mar '14

High speeders Strong relays are a powerful contribution. As long as they are robust to resist misuse by attackers. Last night I received around 250.000 circuits per 5 minutes over one hour on a 100Mbit relay. In case the relay would forward this it could harm someone who is not prepared. And I would be a part of the sender chain.

ScrambleSuit maintenance question
by Delton Barnes 07 Mar '14

07 Mar '14

Inexperienced Debian administrator here with a question about how to maintain the new obfsproxy/Tor for ScrambleSuit. I installed as follows: 1. Updated /etc/apt/sources.list (new lines prefixed with *): deb http://server.name.redacted/debian wheezy main contrib non-free *deb http://server.name.redacted/debian unstable main contrib non-free deb http://server.name.redacted/debian-security wheezy/updates main contrib non-free deb http://deb.torproject.org/torproject.org wheezy main *deb http://deb.torproject.org/torproject.org tor-nightly-master-wheezy main 2. Created apt.conf to prevent all packages from being pulled from unstable by default: echo 'APT::Default-Release "stable";' > /etc/apt/apt.conf 3. Edited torrc with following: ServerTransportPlugin obfs3,scramblesuit exec /usr/bin/obfsproxy managed 4. Installed the new packages: apt-get update apt-get -t unstable install obfsproxy apt-get upgrade <-- Installed Tor nightly. 5. service restart tor My question: Is there a way to configure things so obfsproxy and Tor will later automatically be upgraded to a *stable* release that includes ScrambleSuit? And how to know when I need to upgrade obfsproxy and Tor? Thanks, Delton

problem with tor-arm
by manu 06 Mar '14

06 Mar '14

Hello! I use tor-arm to manage my relay, at startup the following messages appear: [ARM_NOTICE] Unable to prepopulate bandwidth information (insufficient uptime) [ARM_NOTICE] Unable to save configuration descriptions (permission denied: '/home/username/.arm') Problem is the same for every user who runs arm (root, debian-tor) Already tried 777 this folder, and make "debian-tor" the owner - without success. Purge & reinstall does not change anything. I am running Ubuntu Server 12.04 x64. Whats wrong? best regards manu

Tor hidden services – a safe haven for cybercriminals
by an.to_n-73＠riseup.net 05 Mar '14

05 Mar '14

Hey folks! Something to read from Kaspersky Labs: https://www.securelist.com/en/blog/8187/Tor_hidden_services_a_safe_haven_fo… Interesting is, that Eugene Kaspersky hisself states in an interview: "We cooperate not only with the FSB, but also with the Americans and Brazilians, and with a variety of European agencies on security issues or cybercriminals. We sit a group of experts who break the code better than anyone in the world - perhaps only after the FBI. They understand, disassembles, analyze codes and understand what it is the best in the world. People come to us, "Guys, what is it?" - And we respond. We are not able to engage in all sorts of detective work, it's not our job, but we give them the information on which they continue to catch criminals. Or, conversely, we can see some information that may seem interesting to them, and we give them. Sometimes, in Germany looking for stolen laptops, we gave IPs" You can use Google translate to read the whole Russian interview in your language: http://lenta.ru/articles/2013/10/01/kaspersky Facing the overwhelming bulk surveillance I encourage everyone to start more relays/bridges! ==> Are there public statistics about the fraction of illegal content in/from Tor? Is it significantly more than in the "normal"net? We need some counter-arguments. Our "adversaries" will continue putting us in the criminal/terrorist/child-abuse category. But distributed P2P anonymizers like Tor, I2P, GNUnet, Bitmessage etc. are the only technology that helps against mass surveillance.

Advise on fully using a gigabit connection
by Jesse Victors 05 Mar '14

05 Mar '14

Hey everyone. I manage an exit at a university, and I recently moved it to a gigabit connection. I did some tests and the machine does appear to be capable of fully using the available bandwidth. Besides getting two Tor instances to run side-by-side on the same IP, is there anything else I can do to further contribute the connection besides waiting and maintaining uptime? I set my average and burst bandwidth limits to the maximum upload speed I have been able to achieve in my tests, is that an ideal setting? Please advise. Thanks.

TTTT - Reached 100 runs
by Sebastian Urbach 05 Mar '14

05 Mar '14

Dear list members, We are celebrating the century of submitted results, so to say. The "Trying Trusted Tor Traceroutes" project finally reached 100 completed runs from different ip's (not to mention the multiple runs). No one expected that just a few weeks ago when we were basically nowhere. Thank you very much for your support, you officially rock ! The data analysing is going on and hopefully we can draw conclusions from the collected data. The last time at the Chaos Communication Congress was not satisfying for all of us, but we are optimistic this time that there is sufficient data to do it. We will inform this list as soon as we have news. Thanks again from Anupam and myself (He's travelling at the moment) The project: http://web.engr.illinois.edu/~das17/tor-traceroute_v1.html The results: http://datarepo.cs.illinois.edu/relay_scoreboard.html -- Mit freundlichen Grüssen / Sincerely yours Sebastian Urbach ---------------------------------------------- Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety. ---------------------------------------------- Benjamin Franklin (1706 - 1790), Inventor, journalist, printer, diplomat and statesman

Unless you max out /all/ your CPU cores, you can and should simply spin up more Tor processes in parallel, one per CPU core, and limit their bandwidth so they never hit 100% CPU usage. -- Moritz Bartl https://www.torservers.net/ ------------------------------ Message: 2 Date: Tue, 4 Mar 2014 00:43:54 -0800 From: "dope457" <dope457(a)riseup.net> To: tor-relays(a)lists.torproject.org Subject: Re: [tor-relays] Exit Relay on VPS by WEDOS Message-ID: <0da23911717602772537f88415043d39.squirrel(a)fruiteater.riseup.net> Content-Type: text/plain;charset=utf-8 Thanks for the reply.

Single IP multiple OR Ports
by Felix 04 Mar '14

04 Mar '14

Hi to all - I have a question: In case there is a strong relay ie 1Gbit/s, enough cores and RAM so the HW is not limiting. Let's further assume only one IP. Could a single Tor daemon on Debian be a bottle neck? If yes, could be more performance to start two (or more) daemons and bind the first OR Port to :443 and the second to :8080. Both at the same 'eth' interface? Both OR Ports are based on the same IP so they would be the same family member. Thanks for your answer. My response might have some delay. Sorry for that.
