Relay Database: Existing Schemas?
by nusenu 26 Feb '16

26 Feb '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi, I'm planing to store relay data in a database for analysis. I assume others have done so as well, so before going ahead and designing a db schema I'd like to make sure I didn't miss pre-existing db schemas one could build on. Data to be stored: - - (most) descriptor fields - - everything that onionoo provides in a details record (geoip, asn, rdns, tordnsel, cw, ...) - - historic records I didn't find something matching so far, so I'll go … [View More]

[Patch] or/config.c for MSVC
by Gisle Vanem 23 Jul '15

23 Jul '15

This gcc-centric macro in or/config.c doesn't work well in MSVC v16/18: #define COMPLAIN(args...) \ STMT_BEGIN log_warn(LD_CONFIG, args); STMT_END I suggest it should be patched like this: --- a/config.c 2015-05-06 22:22:09 +0000 +++ b/config.c 2015-05-06 23:15:57 +0000 @@ -2571,8 +2571,8 @@ #define REJECT(arg) \ STMT_BEGIN *msg = tor_strdup(arg); return -1; STMT_END -#define COMPLAIN(args...) \ - STMT_BEGIN log_warn(LD_CONFIG, args); STMT_END +#define COMPLAIN(args, ...) \ +… [View More]

Update: Proposal 237 - All relays are directory servers
by Matthew Finkel 09 Jul '15

09 Jul '15

Hi All, Here's an updated version of prop 237. I rewrote some parts for clarity and brought it inline with the current implementation for #12538. Updated branch on prop237_update in my torspec repo. Thanks! Matt

Tor Messenger Third Alpha
by Sukhbir Singh 01 Jul '15

01 Jul '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, Tor Messenger: - sends all traffic over Tor, - enforces Off-the-Record Messaging (OTR) for one-on-one conversations by default, - can be used with a wide variety of … [View More]chat networks, - has an easy-to-use graphical user interface localized into multiple languages. * Current Status Today we are releasing the third alpha version with which we hope to gain both usability and security related feedback. There have been two previous alpha releases to the mailling lists that have already helped smooth out some of the rougher edges. * What's New in Tor Messenger 0.0.6 - Support for Windows and OS X builds (in addition to Linux) - Improved privacy and security with network and application-related enhancements - Improved usability of the Instantbird OTR extension - Private key and known fingerprint management - XMPP in-band account registration support - Build localization support (currently Arabic; Chinese, Spanish, Farsi, and other languages coming soon) * Bundles Linux (32-bit): https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/tor-messenger-0.… Linux (64-bit): https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/tor-messenger-0.… Windows: https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/tor-messenger-0.… OS X: https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/tor-messenger-0.… sha256sum: https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/sha256sums.txt https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/sha256sums.txt.a… The bundles are signed with the key 0xB297B391. * Instructions - On Linux, extract the bundle and then run: ./start-tor-messenger. - On OS X, copy the Tor Messenger application from the disk image to your local disk before running it. On all platforms, Tor Messenger sets the profile folder to the installation directory. * Code We are doing automated builds of Tor Messenger for all platforms using rbm (Reproducible Build Manager): https://gitweb.torproject.org/tor-messenger-build.git * Arabic Language Pack https://people.torproject.org/~sukhbir/tor-messenger-0.0.6/tor-messenger-ar… Install the language pack as an add-on and then set "general.useragent.locale" to "ar". (Thanks to Sherief Alaa for the translation.) * Feedback 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. 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 (bugs.torproject.org; select the "Tor Messenger" component). You can also talk to us on this mailing list or on IRC.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Yep, you got it! People find it easiest to read mailing list posts if the subjects match. And the threading works better that way, too. Any time you reply to and quote a previous email, cut out the extra stuff the mailing list adds in. And cutting out people's long signatures helps, too. Imagine you've googled a problem, and you're reading each email by itself - what do people need to know to follow the conversation? > I see now about top-… [View More]

Chutney Please … [View More]use the official chutney repository at git.torproject.org <http://git.torproject.org/> My chutney repository a little messy at the moment, and I've merged draft throughput-testing code into my master branch. You're welcome to test the draft code by merging https://github.com/teor2345/chutney/tree/bug14175-bandwidth <https://github.com/teor2345/chutney/tree/bug14175-bandwidth> The throughput-testing functionality works, but it needs to be tidied up, and have the hard-coded constants turned into command-line options. So it's not ready for release, but it is ready for an early review to check for functionality gaps and bugs. You might find throughput metrics useful to confirm that any multithreading changes are actually improving performance. Testing Once tor is built, you can test it using: # basic tests make test # extended tests make check # benchmarks /src/test/bench # verify tor connectivity using a local test network - requires chutney make test-network # verify that the core functionality of tor works, requires chutney and IPv6 on localhost src/test/test-network.sh --flavour bridges+ipv6+hs # verify that the core functionality of tor works, using chutney, but without IPv6 src/test/test-network.sh --flavour bridges src/test/test-network.sh --flavour hs There's also various other testing tools: shadow Tor network simulator static analysers, such as coverity and clang-scan dynamic sanitizers: Undefined Behaviour (UBSan), Address (ASAN), … fuzzing (I'm working on some tor-specific harnesses for fuzzing, but they're not ready) and I'm sure there are others which I've missed. Generally, I'm happy with code once I know it: * compiles with no warnings, * passes the extended unit tests (make check), including any tests written for new functionality, and * passes all the connectivity tests in a comprehensive test network (bridges+ipv6+hs). For bonus points, you can compile tor using UBSan and ASAN. If you're using clang, you'll find that tor/contrib/clang helps with setting this up. It lists known undefined behaviour in the Tor codebase, so it may be useful if you want to do something similar with gcc. (However, getting sanitizers to work can be incredibly fiddly and a total time-suck, too. So if it's just not working, skip it.) I'll also occasionally run code through a static analyser, to find subtle bugs which haven't been uncovered using UBSan/ASAN. Again, this isn't something everyone needs to do. Others may have advice on testing multithreading code in particular.

Thanks teor, that'd be awesome! I've been able to resolve most of the dependencies easily until the file "readpassphrase.h" (and thus .o) was shown to be missing during make. Are you still using the git branch? I'll definitely take a look into the throughput tool once I get set up :D - Cory On Mon, Jun 29, 2015 at 5:00 AM, <tor-dev-request(a)lists.torproject.org> wrote: > Send tor-dev mailing list submissions to > tor-dev(a)lists.torproject.org > > To subscribe or … [View More]unsubscribe via the World Wide Web, visit > https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-dev > or, via email, send a message with subject or body 'help' to > tor-dev-request(a)lists.torproject.org > > You can reach the person managing the list at > tor-dev-owner(a)lists.torproject.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of tor-dev digest..." > > > Today's Topics: > > 1.
