Hi, I want to control the window size of Firefox browser and whether a plugin is enabled or disabled when a new firefox browser is opened. Currently I'm using a Tor browser which is a modified firefox browser, when I open it, the window size is set by default and flash plugin is by default disabled. even if I try to set them mannually, the next time I open a new firefox window, the setting return to default. I want to know which configuration files or what part of the source codes are controling this default setting, and I want to modify it. can anybody give me some solution or hints? thanks!

The Tor Project is looking for a Pluggable Transport developer
by Roger Dingledine 05 Oct '12

05 Oct '12

We have funding initially for part-time work, and hopefully it will grow into full-time work. Please spread the word! This job is for the development and maintenance of the flash proxy circumvention system, with a focus on deployment and getting tools in the hands of users: https://crypto.stanford.edu/flashproxy/ https://gitweb.torproject.org/flashproxy.git/ If it goes well, we might have you branch out into improving usability and deployability of other Tor pluggable transports. Applicants must be familiar with Python, JavaScript, and web technologies, particularly WebSocket. You will do usability testing and be in charge of producing binary packages of client software for GNU/Linux, Windows, and OS X. The system's supporting infrastructure is already in place, but may require changes depending on the future development of the client programs. There also is the potential for the development and implementation of new covert rendezvous methods that may have broader use outside the flash proxy system. You will be assisted and mentored by David Fifield, the primary developer of the flash proxy software and co-author of its research paper, and all-around good guy. See the job posting for information on how to apply and what you need to send in with your application: https://www.torproject.org/about/jobs-pluggabletransport Thanks! --Roger

resistance to rubberhose and UDP questions
by Eugen Leitl 04 Oct '12

04 Oct '12

I've had an IRC session with the designer of cjdns (on cjdns) who made a few interesting points, and suggestions. Comments? Verbatim chat snip below. 18:03 <@cjd> if you took the components from cjdns, you could build a TOR like protocol which used UDP if possible and made connections much faster 18:04 <+eleitl> I wonder why they didn't choose UDP 18:05 <@cjd> you need to fall back on tcp in case you're firewalled to hell 18:05 <+eleitl> Apparently, they're thinking about it https://blog.torproject.org/blog/moving-tor-datagram-transport 18:06 <@cjd> problem with tor is (correct me if I) 18:06 <@cjd> 'm wrong) 18:06 <@cjd> the directory is signed by the tor foundation 18:07 <@cjd> so they can sign a fake directory and run a bunch of directory servers and when Alice connects to their directory server, they give her a bunch of fake nodes 18:07 <@cjd> run their own botnet with fake tor nodes so your circuit is always owned 18:07 <+eleitl> I don't really know for sure, but there's intrinsic trust to Tor developers, yes. 18:08 <+eleitl> You can run your own Tor network, though. 18:08 <+eleitl> Some botnets do that. 18:08 <@cjd> I trust them to make the software right, esp. since I could check if they did. 18:09 <@cjd> But a little arm twisting can change someone's motives pretty fast. 18:09 <+eleitl> Maintaining signing secrets is a problem. 18:09 <+eleitl> They should have used a P2P design. 18:10 <@cjd> If someone (with government hat?) tells you they can make your life hell... I wouldn't fault them for doing what the man says. 18:10 <@cjd> *wouldn't fault you 18:10 <+eleitl> I'll try bugging some Tor developers about that scenario, and see how they squirm. 18:11 <+eleitl> Also, the UDP connection thing. 18:11 <@cjd> You can "stack" your circuit setup packets if you're using UDP 18:11 <@cjd> stack -> all headers in the same packet 18:12 <@cjd> cjdns does the same thing 18:13 <+eleitl> Can I use snippage from this chat verbatim, or will I need to rephrase? 18:14 <@cjd> sure go ahead 18:14 <+eleitl> Thanks! 18:14 <@cjd> can only speak for myself ofc 18:14 <+eleitl> Sure.

Damian's Status Report - September 2012
by Damian Johnson 04 Oct '12

04 Oct '12

Hi all. As is often the case work and such meant not too much time for tor. For September all I have to report is... * Network Status Document Parsing This has been my main focus for September and it's still not finished... but it's close! Version 3 document parsing just has a couple days of work left, then abstracting it to cover v2 documents and microdescriptors should be relatively easy-ish. I'm really looking forward to merging this feature branch. It has grown quite monstrous... https://gitweb.torproject.org/user/atagar/stem.git/shortlog/refs/heads/docu… * Stem Documentation Hosting For a while now I've had a TODO item for making a nightly cron that built and hosted Stem's new sphinx documentation. I was about to do this when I recalled that meejah once recommended ReadTheDocs, a service that does... well, exactly that. After a few minor bumps [1][2][3] it's now live... https://stem.readthedocs.org/ We definitely need to put effort into making them more reader friendly. At present it's just a dump of all the pydocs which, while informative, is actually a bit overwhelming for new users. Module summary pages would greatly help. * MAPADDRESS Support Ravi submitted a patch for adding MAPADDRESS support to stem's controller. It's a nice addition, especially the integ test... https://trac.torproject.org/6951 * Arm Issues Looked into a couple arm issues... - Tor's start time didn't show up if the system has proc contents but we fail to parse it [5]. - Can't connect when using a control socket with password auth [6]. * Updated Dev Wiki In response to a potential volunteer I wrote a summary of several development tasks [4]. Updated stem's wiki with what was in that email... https://trac.torproject.org/projects/tor/wiki/doc/stem Cheers! -Damian [1] https://github.com/rtfd/readthedocs.org/issues/255 [2] https://github.com/rtfd/readthedocs.org/issues/256 [3] https://gitweb.torproject.org/stem.git/commitdiff/705b61674e8cec9e5608a32c6… [4] https://lists.torproject.org/pipermail/tor-dev/2012-September/004021.html [5] https://trac.torproject.org/6862 [6] https://trac.torproject.org/6881

Hi All I am a bit curious to know how does the traffic scheduling work in the present Tor distributions. Is it EWMA or the old round robin method ? Thanks Sambuddho

by jiang song 30 Sep '12

30 Sep '12

Hi, If I use firefox, I can use a simple command line to open a link in a new tab automatically, like firefox www.google.com now I want to open TBB first, and then open a link in a new tab, is there any script or method to automate this operation? I need this automation for some experiment, I know TBB is a modified firefox, so if there are TBB developes here, they may know how to do this, thanks!

Help with pf and iOS
by sid77＠slackware.it 28 Sep '12

28 Sep '12

Hi all, it took me a year or so but I've finally managed to build Tor for iOS with a working support for TransPort, as you can see on: https://github.com/sid77/evelyn/blob/master/tor/make.sh The next natural step is to hack together full device torification as iOS jailbroken devices can run pf (without ALTQ support). I'm not very comfortable with pf and pfctl so my first step was to head out to https://trac.torproject.org/projects/tor/wiki/doc/TransparentProxy#BSDPF looking for some clue. However, jailbroken iOS' ifconfig can not bring up a second loopback interface (I think the kernel is not allowing it) so I had to test out some custom rules, my current pf.conf is as follow: -8<- scrub in rdr pass on lo0 inet proto tcp all -> 127.0.0.1 port 9040 rdr pass on lo0 inet proto udp to port domain -> 127.0.0.1 port domain block return out pass quick on lo0 keep state pass out quick inet proto tcp user nobody flags S/SA modulate state pass out quick route-to lo0 inet proto udp to port domain keep state pass out quick route-to lo0 inet proto tcp all flags S/SA modulate state -8<- taken from: https://github.com/sid77/mobiletor/blob/master/pf.conf I apply it running this script: https://github.com/sid77/sbsettingstor/blob/master/com.sbsettingstor.enable Tor is running as user nobody (not really secure but I still have to figure out system user management on the platform) and answering DNS queries on 127.0.0.1:53. This solution is failing *REALLY* hard as I managed to run into a kernel panic as soon as I tried to generate some traffic with Mobile Safari or Cydia. Is there any pf guru out there which can give me some insights? Ciao, Marco
