Researchers Find Gaps In Iranian Filtering

I Don't Believe in Imaginary Property writes "With all the turmoil and internet censorship in Iran making it difficult to get an accurate picture of what's going, security researchers have found a way to locate gaps in Iran's filtering by analyzing traffic exiting Iran. The short version is that SSH, torrents and Flash are high priorities for blocking, while game protocols like WoW and Xbox traffic are being ignored, even though they also allow communication. Hopefully, this data will help people think of new ways to bypass filtering and speak freely, even though average Iranians have worse things to worry about than internet censorship, now that the reformists have been declared anti-Islamic by the Supreme Leader. Given the circumstances, that declaration has been called 'basically a death sentence' for those who continue protesting." Reader CaroKann sends in a related story at the Washington Post about an analysis of the vote totals in the Iranian election (similar to, but different from the one we discussed earlier) in which the authors say the election results have a one in two-hundred chance of being legitimate.

    This is ridiculous. You can't just conjure up some irrelevant examples and use them as an argument when they have absolutely nothing to do with it. E.g. with the coin flip test, the correct analogy would be to check what the chances are for less than 40 heads/more than 60 tails after 100 coin flips. The chances for this happening are indeed very low. That is why it is so impressive that they had 5% of the times 5 as last digit and 17% a 7. The 1/200 is not the chance to have the 5% and 17% (that would be a lot lower) but the chance of having suspicious results vs. the chance of them being false.
    Besides: n/o but I'd rather believe a study made by two PhD students instead of some slashdotter.

    Hi, I'm an Iranian and i've been tortured by the internet filtering here for a few years but the filtering after election is really terrible, we can't use the old ssh tunneling methods any more, in fact it seems that all encrypted packages are being dropped so we can't connect to our servers out side of Iran any more so we can't use another method for passing through the filtering, however today i've used a browser based ssh client to connect to my VPS in Germany and installed a proxy using squid but the interesting thing is that we i try to connect to facebook (or any other filtered website) the firewall changes my request to the famous "This site is blocked" page! These things was just examples of methods we tried to pass the filtering, anyway we are using other method to pass the filtering (which i will not mention here for safety!) but we have serious problems connecting to our servers over ssh, i'm going to test the ssh over http method but i know that this will be a temporary method!!!

      Make sure your DNS accesses are tunneled as well.
