New Pluggable Transports bundles 0.2.4.11-alpha (flashproxy + obfsproxy)

We've updated the Pluggable Transports Tor Browser Bundles with Firefox 17.0.4esr and Tor 0.2.4.11-alpha. These releases have numerous bug fixes and a new Torbutton as well.

Like the previous bundles, these contain Flashproxy and the Python version of Obfsproxy.

Flash proxy is a transport that uses proxies running in web browsers as access points into Tor. Obfsproxy is a pluggable transport that makes network traffic look unlike normal Tor traffic. Both of these technologies make it harder to block access to Tor. If you previously used the obfsproxy bundle, please upgrade to this bundle, which in addition to flash proxy has new obfsproxy bridges.

Flash proxy works differently from other pluggable transports, and you need to take extra steps to make it work. In particular, you will probably need to configure port forwarding in order to receive connections from browser proxies. There are instructions and hints on how to do that at this page: flash proxy howto.

These bundles contain the same hardcoded obfs2 bridge addresses as the previous bundles which may work for some jurisdictions but you are strongly advised to get new bridge addresses from BridgeDB: https://bridges.torproject.org/?transport=obfs2.

Furthermore, we are looking for feedback on how the bundles work. Please leave comments on the flash proxy usability wiki page or ticket #7824 with your experience, good or bad.

There are other ways you can help beyond testing the bundles. One is to run a bridge with pyobfsproxy. Another is to put the flash proxy badge on your web site or blog, or add it to your Wikipedia profile. If you want your browser to continue to be a proxy after a switch to an opt-in model, click the “Yes” button on the options page.

Anyone has same problems? I have two PCs working in same network ADSL+router.
Flashproxy-reg-email works well in the PC running WIN7; but flashproxy-reg-email doesn't work in the PC running XP sp3, here is the details:

I have the same problem. Tor (flashproxy) doesn`t work in PC running win xp , however it works in PC runnig win vista.

Same error here, on a Win7 64bit PC:
2013-03-23 13:34:46 flashproxy-reg-email: Failed to register: [Errno 1] _ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
2013-03-23 13:34:46 flashproxy-reg-email exited with status 1.

Anybody knows what's the culprit?
Using Tor Browser out of the the latest pluggable transports bundle or w/ additional port forwarding result in same situation.

TOR, recent two weeks,very difficult to connect to tor network in China,even I use sock5 proxy, it is hard to connect. and after connecting, I remove proxy, and restart nearly the same time, but couldn't connect again.Could your people have a check the Tor status now in China?
Fuck GFW.

The obfsproxy TBB should work in China. Probably not out-of-the-box since the GFW tends to blacklist the hard-coded bridges contained in the bundle. So you will probably need new obfsproxy bridges: https://bridges.torproject.org/?transport=obfs2

and more now in China, I use proxy to connect tor, when tor start firefox, the firefox broswer just couldn't connect too, shows, proxy refuse to connect.

You need fresh bridges: https://bridges.torproject.org/?transport=obfs2

Sorry thats i write here, but i have in the normal browser bundle
often app.exe crash. when i close tor. how can i help and report it? Is there any log that i can e-mail to support?

I think your windows firewall blocks flashproxy-client and pyobfsproxy.
可能是你电脑防火墙拦住了它们,建议你检查设置。

没装防火墙。但是以前的版本Tor Flashproxy Pyobfsproxy Browser 2.4.7使用正常。

this new one is slower than the first one!
but it WORK fine
irani!

I'm confused:

I want to use the obfsproxy 'server' (if that's correct) TBB to help those users that need to use obfsproxy, while I would connect directly with my Tor client, is this the bundle I would use?

IIRC, at one time there was a test obfsproxy TBB I used that was an obfsproxy server, I forwarded ports for the server, and it ran well.

hi again
1-it got a long time for connecting to relays
2-it seems have not compatibility with some website elements! it go in (not respond)mode and at least i must exit tor and restart it again and stop the website when it is loading is not complete
irani!

China here, i've been successfully using flashproxy 2.4.7 alpha1 for the last 2 months or so.
Last week i tried to update to the new bundle 2.4.11 alpha1 but it didn't work, giving notice that the proxy server refused the connection.
(First the hardcoded bridges din't work, then i tried the ones i've been using, but with no success.)
I "rolled back" to the previous version (2.4.7 alpha1) and it's again working fine with those same bridges that "failed" with 2.4.11 alpha1.
Keep on the good work, thank you so much for making this progressive software available for anyone who wants to use it.

[Warning] Not using bridge at [scrubbed]: it is in ExcludeNodes.

Sounds like you should set ExcludeNodes then?

I am in China. Just got 2.4.12-alpha for linux. Getting message "server rejected". Should I try adding more bridges? When I add bridges should I also delete some? If yes, which ones? If I need to add more, how many?
