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!!!

The reformist side which lost the election tries to use internet for spreading the news using facebook, twitter, messengers and mailing lists. The government blocked all the reformist websites and also blocked all the social networking websites, as they know that many people can pass the government filtering they tried to make attacks against reformist websites, they placed malicious code in their website which use visitors computer to attack reformist websites as a response reformist side did some DOS attacks against the government websites and it seems that the reformist side won the website war as the government websites are unavailble and the reformist website are working fine. As government seemed to be losing the cyber war they started a new approach in sensorship by blocking vpn and ssh connections which many people use to pass the filtering. We were not sure about this untile I understood that I can't connect to any server in anywhere in the world using ssh and I called some of my friends , we tried to change the port but it seems that the filtering is based on packet inspection not just port blocking. The government also blocks messenger access and I can't even connect to IRC networks! How should I pass this unfair filtering system?!!! http://www.channel4.com/news/articles/politics/international_politics/whoaposs+winning+iranaposs+cyberwar/3214857 http://www.cbc.ca/technology/story/2009/06/16/iran-twitter-netwar-greg-walton-citizen-lab.html http://www.cnn.com/2009/WORLD/meast/06/17/iran.elections.hackers/ http://www.fastcompany.com/blog/kit-eaton/technomix/iranian-protests-becoming-crowd-sourced-cyber-war-sorts"
