How many exits exit from an IP address different than their OR address? (10.7%)
by David Fifield 17 Jan '16

17 Jan '16

I wanted to know how many exits exit from an address that is different from their OR address. The answer is about 10.7%, 109/1018 exits. The interesting part is that of those 109 mismatches, 87 have an exit address that differs from the OR address in all four octets; i.e., the IP addresses used by the exit are not even in the same /8. Also, there are several groups of exits whose OR addresses *are* in a related subnet, but which all exit through the same, unrelated, IP address. See for example 109.236.82.* (all exiting through 185.108.128.7), 178.17.171.* (all exiting through 37.48.65.71), and 217.23.11.* (all exiting through 85.17.31.120) in the table below. I wrote an exitmap module that hits an IP-checker website. The module wrote a CSV file where each row included the exit's OR address and the address as reported by the remote web site. I ignored IPv6 OR addresses. I did not find any fingerprint that had more than one IPv4 address (considering the .fingerprint and .or_addresses members from Stem). Percentages are just raw counts, not weighted by exit probability. Total number of exits: 1018 (100.0%) Number of failures: 18 (1.8%) Number of matches: 891 (87.5%) Total number of mismatches: 109 (10.7%) Number of 1-octet mismatches: 19 (1.9%) Number of 2-octet mismatches: 3 (0.3%) Number of 3-octet mismatches: 0 (0.0%) Number of 4-octet mismatches: 87 (8.5%) Table of mismatches * = mismatch 1 octet ** = mismatch 2 octets *** = mismatch 3 octets **** =

Re: [tor-dev] Comparing Stem, metrics-lib, and zoossh

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello Philipp and iwakeh, hello list, Damian and I sat down yesterday at the dev meeting to talk about doing a comparison of the various descriptor-parsing libraries with respect to capabilities, run-time performance, memory usage, etc. We put together a list of things we'd like to compare and tests we'd like to run that we thought we'd want to share with you. Damian and I will both be working on these for metrics-lib for a short while and then switch to Stem. Please feel free to join us in these effort. The result is supposed to live on Stem's home page unless somebody comes up with a better place. Thanks!

The broader idea is to determine which Tor torrc settings are relevant to the mobile environment, and that could use a more intuitive user interface than the empty text input we currently offer in our Settings panel. This may also mean implement a slider type interface mechanism similar to Tor Browser. In addition, users are interested in being able to control which network types (wifi vs 3g) Orbot runs on, in order to conserve spending on bandwidth. The Exit country selector option (basically a list of countries that starts with "World" as the option) is definitely controversial, but it is also something that comes up over and over again as a feature request. It is expected especially of a VPN-style app, which Orbot now is. It may be we only enable it when the VPN feature is enabled, and disable it when Tor is used directly via SOCKS from the Orfox browser. We may also need to just sufficiently warn and inform the user so they can decide for themselves what to do. +n

txtorcon: ipaddress instead of ipaddr?
by meejah 13 Jan '16

13 Jan '16

Regarding https://github.com/meejah/txtorcon/pull/155 does anyone have a good reason not to move txtorcon to using "ipaddress" -- this is a built-in library on Python3, with backports to Python2. Thanks, meejah

Needs Code Review: Shared Randomness Generation for Tor
by George Kadianakis 13 Jan '16

13 Jan '16

Hello there, we are happy to tell you that we finished coding proposal 250 and our first attempt at implementation is ready for review. You can find the final specification here: https://gitweb.torproject.org/user/dgoulet/torspec.git/log/?h=prop250_final… and the corresponding code here: https://gitweb.torproject.org/user/dgoulet/tor.git/log/?h=prop250_final_v1 Trac ticket #16943 (https://trac.torproject.org/projects/tor/ticket/16943) will be used for code review. Please use this mailing list to discuss any issues with the spec. Some notes: We've separated this in 7 commits prefixed with prop250: except first one that adds a needed tor_htonll/ntohll function to tor utils. This code is mostly contained in two *new* files (with their headers) that are shared-random.{c|h} and shared-random-state.{c|h}. For what it's worth, we expect this code to run for a long time before the shared random values generated by the authorities are used for anything (e.g. HSDir scrambling). Cheers!

Questions about censorship detection paper
by John 13 Jan '16

13 Jan '16

Hi, I ran into the technical report from George Danezis about an anomaly-based censorship-detection system for Tor. I have a few questions that I hope you can help me with. Is there an implementation available of the approach described in the paper? The paper talks about finding anomalies in the time series of the number of requests to directory servers from certain jurisdictions. Where can I find this data about the requests to directory servers? --john [1] https://research.torproject.org/techreports/detector-2011-09-09.pdf

Fwd: Orbot roadmap feedback
by Nathan Freitas 12 Jan '16

12 Jan '16

I've got big plans for Orbot in 2016... any thoughts on the roadmap below, particularly how it aligns with Tor core roadmap, would be appreciated. ----- Original message ----- From: Nathan of Guardian <nathan(a)guardianproject.info> To: guardian-dev(a)lists.mayfirst.org Subject: Orbot roadmap feedback Date: Mon, 11 Jan 2016 22:58:05 -0500 Here is my current set of brainstormed ideas for Orbot that I am currently working through... please add, edit, improve and prioritize as you are willing and able. - Continued inclusion of the latest and greatest pluggable transports (Obfs*, Meek, ???) - Improved support for requesting and configuring Obfs4 bridges - directly integrate with BridgeDB to provide streamlined way for people to get bridges where Tor is blocked - More Orbot VPN features including better UI for enabling/disabling Tor routing, blocking specific apps, ports and/or hosts, and general "firewall" or little snitch type features within the Orbot VPN - OrbotShare: an OnionShare inspired file sharing and download manager service to enable easy hidden service .onion setup and sharing (including support for new ephemeral onions) - OrbotRelay/Bridge: improved UI for running a bridge or relay from within Orbot, including support for scheduled times (night only) or states (only when plugged in, on wifi, and screen is off, etc) - Removal of Polipo, in favor of new streamlined in process HTTP proxy (less memory use, and more stable) - Creation of LibOrbot module/library for use by any app to embed Tor into their app - Overall improved configuration / settings UI to make tuning Orbot a better, simpler experience... this is an expansion of the new exit country selector in Orbot v15.1, but also includes managing things like network usage and so on. - OrbotWear / OrbotTV: Should we expand Orbot support to other Android platforms like watches and Smart TVs? Perhaps Orbot relay/bridge mode could run on a TV or set top box? - Some sort of "Pro" or Donation-ware version to allow a pay-what-you-can concept within the app Good, bad, ugly? Let me know! -- Nathan of Guardian nathan(a)guardianproject.info
