Regarding contributing to torproject
by Vipul Sharma 27 Jan '15

27 Jan '15

Hello developers, I have some experience in Python/Django and looking to contribute to torproject. I've read about many projects mentioned at: https://www.torproject.org/getinvolved/volunteer.html.en#Projects but still I need your help and advice to pick a project. Please suggest me which project should I look for, considering that I am new to torproject :) Apart from this, there are few questions I would like to ask: - Which is the best place to ask questions: mailing list or irc(#tor-dev) (I don't want to spam with my questions in this mailing list) ? - How should I communicate or notify before sending a PR ? - Is it necessary to issue a ticket before sending a PR ? (Supposing that I've found an issue) I know these are pretty novice questions but I need your help :) Regards, Vipul Sharma

Stem descriptor lazy loading
by Damian Johnson 25 Jan '15

25 Jan '15

I've been wanting to do this for years. Just a quick announcement that Stem now lazy-loads descriptors, giving it a nice performance boost... Server descriptors: 27% faster Extrainfo descriptors: 71% faster Microdescriptors: 43% faster Consensus: 37% faster For details see... https://gitweb.torproject.org/stem.git/commit/?id=3dac7c5 Note that descriptor validation is now opt-in rather than opt-out, so if you'd prefer validation over performance you'll now need to include 'validate = True'. This is a pretty big overhaul so please let me know if you run into any issues. Cheers! -Damian

RFC: Tor Messenger Alpha
by Sukhbir Singh 25 Jan '15

25 Jan '15

Hi, Tor Messenger is an instant messaging client currently under development. It is designed to make connections using the Tor network and will therefore be a valuable piece in the privacy-enhancing software toolkit (web: Tor Browser, email: Thunderbird + TorBirdy, chat: Tor Messenger.) Based on the Instantbird IM client [0], Tor Messenger: - sends all traffic over Tor, - uses Off-the-Record (OTR) encryption [1] of conversations by default, - can be used with a wide variety of chat networks, - has an easy-to-use graphical user interface localized into multiple languages. Some more information about Tor Messenger (and why we picked Instantbird) can be found on the wiki [2]. Current Status We have Tor Messenger bundles for Linux (32-bit and 64-bit) with OTR (using ctypes-otr [4]) and Tor support (Tor binary and Tor Launcher included), among other privacy settings. We are doing automated builds of Tor Messenger using rbm [5] (thanks to Nicolas Vigier). @@@ WARNING: NOT READY FOR PUBLIC USE. DO NOT DISTRIBUTE. @@@ Bundles Linux (32-bit) https://people.torproject.org/~sukhbir/tor-messenger-0.0.4/tor-messenger-0.… Linux (64-bit) https://people.torproject.org/~sukhbir/tor-messenger-0.0.4/tor-messenger-0.… sha256sum https://people.torproject.org/~sukhbir/tor-messenger-0.0.4/sha256sums.txt https://people.torproject.org/~sukhbir/tor-messenger-0.0.4/sha256sums.txt.a… The bundles are signed with my key (Sukhbir Singh; 0xB297B391). Extract the bundles and then run: ./start-tor-messenger. This is an early release and there may be serious privacy leaks and other issues -- please DO NOT recommend Tor Messenger to end users; this release is only for developers and advanced users who would like to help us with testing but understand the risks involved with using alpha software. Do not ignore this warning. We will try to have a monthly release cycle leading up to a stable release by July 2015. @@@ WARNING: NOT READY FOR PUBLIC USE. DO NOT DISTRIBUTE. @@@ Feedback With this release, we invite feedback not limited to anonymity leaks, usability issues, feature requests and suggestions for improvement. Please submit your feedback using the bug tracker [3] (select the "Tor Messenger" component). You can also talk to us on this mailing list or on IRC. (No seriously, don't use the bundles for any serious communication yet.)

Event at NEXA center and next OONI dev meeting
by Arturo Filastò 23 Jan '15

23 Jan '15

Hello Oonitarians! We skipped this weeks meeting due to a lot of us being busy with an event at the NEXA center. It was a very interesting opportunity to meet a lot of great network measurement and network neutrality researchers and discuss possible areas of collaboration. I will give a brief summary of some of the most relevant things WRT OONI. # Libight hackfest On the first day we did a hackfest on libight. At the end of it we were able to produce a build of libight for iOS [1] as well as a mockup of the GUI [2]. We also finished the integration of the SOCKS client [3] that will allow us to use tor from libight. Overall we are quite close to having a working prototype for iOS and soon also for Android. # NNTools meeting Enrico Gregori and Valerio Luconi from Italian National Research Council presented their work on Portolan, that is trying to map BGP interconnections with traceroutes. They have developed a desktop and mobile application that is very cool and works well! Later we discussed about possible collaborations, in particular deploying their tests as part of our raspberry pi deployment. For the full schedule of events see: http://nexa.polito.it/nntools2015 Regarding the next developer meeting I am going to suggest we do it as usual on Monday at 19:00 CET (18:00 UTC). That's it, until next week! Have fun! ~ Arturo [1] https://github.com/alemela/libight_iOS [2] https://people.torproject.org/~art/ooni/mockups/ooni-ight-assets.zip [3] https://github.com/TheTorProject/libight/pull/71

Obfsproxy Address Translation
by Alfredo Palhares 23 Jan '15

23 Jan '15

Hello, Recently I've been fighting censorship[1] in the form of deep packet inspection. Between the OpenVPN I an obfsproxy server outside the country and a client inside the country. But what I've found out is that Obfsproxy server needs to be running as the OpenVPN server and Obfsproxy client needs to be on the same machine as the OpenVPN client. This makes stuff work but its not really optimal, since there are area of the country where internation traffic is really hard, having proper address translation would save the hassle of setting another proxy between obfsproxy and the clients would not need anything more than the OpenVPN client that they already have. I opened issue #14217[2] and would like to provide a patch for it. But I am not Python and Twisted expert, so I will be firing a few questions: - How do I debug twisted ? Given the event-diven nature of the library, how do I debug incoming packets ? - How do you write server client tests? - What part of the code is reponsible from translating the incoming packeets on the server back to the client ? Thanks in advance ! [1] https://forums.openvpn.net/topic17960.html [2] https://trac.torproject.org/projects/tor/ticket/14217 -- Regards, Alfredo Palhares

[PATCH] Fix clang warning in test code
by Tim Ruehsen 23 Jan '15

23 Jan '15

There are still 5 reports from clang analyzer. They are either false positives or (in the test code) 'easy-to-read' programming by purpose (easy to get rid of, but absolutely no need to do). Tim
