Of course censors could also just connect to the Tor and use this hidden service to learn about other bridges. Even again and again request new bridges (pretending the previous ones are unreachable) and thus gain the knowledge of all bridges.

If bridges have been chosen for use, the tor might continue to fetch new bridge information every so often via a hidden service that wouldn't, in and of itself, be blockable. tor could be somewhat smart about this, too. For example, if it notices that a bridge has become unreachable, it could request three new ones. Given the possibility that the unreachable bridge might simply be down for the moment, tor could keep it at the end of its list of bridges to try until it had been unreachable for some time period before removing it from its list. Such a procedure would mean that, in many situations, the user would only need to get an initial set of bridges, after which tor would maintain a list of, say, six to twelve bridges that were current for use. At present, bridge users have to remain vigilant and anticipate the blockage or discontinuance of bridges that they have provided to tor, which means that they could become permanently disconnected and unable to get new bridge information. It wouldn't be airtight, to be sure, but it would greatly shrink the window of opportunity for censors to cut bridge users off from the tor network. Scott Bennett, Comm.

That's great news! Thanks for exploring & solving this problem. Myself & many others here in Thailand are very grateful for Tor. *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/

Turns out this was something we could fix in Vidalia. The current version of Vidalia had a hard-coded ssl cert in mind for bridges.torproject.org, but we changed that cert on the site itself. Expect the "find bridges now" button to resume working in a later Vidalia release.

It's possible. It's just a website, and the people running your country's firewall are already good at blocking websites when they choose to. Also, you should notice that the bridges given out via https tend to get blocked earlier than the bridges given out via gmail. So if they do block that website, it may be that the next step is to block the bridges it gives out. > Of course I've been able to obtain & successfully use bridges using > the other [documented] means of acquiring bridges but I'm left > wondering why this connection problem is happening and if anyone else > was having similar problems either in Thailand or elsewhere? A fine question. Last I heard, that website is only blocked in China. --Roger *** To unsubscribe, send an e-mail to majord...@torproject.org with unsubscribe or-talkin the body. http://archives.seul.org/or/talk/
