The Best Way Through the Great Firewall of China

eldavojohn writes "The MIT Technology Review brings news of a new report from Harvard assessing circumvention software. The best tools they tested (and they actually did test them in cybercafes in China) were Ultrareach, Psiphon, and Tor, while Dynaweb and Anonymizer also scored well — of course, the huge downside is the long loading times. The report also includes responses from developers of the tools."

  1. Tunnel SOCKS through SSH? by RT+Alec · · Score: 3, Interesting

    I found that when a client of mine connected via SSH to a well connected server (Equinix/Ashburn), they could use the SOCKS setting in Firefox (connecting to localhost since that's what their SSH client listened to) to tunnel all of their traffic with no problem. Note: this was a Mac, up to date as of last year when we tried this.

    Sure enough, one day the tunneling stopped working! We changed the port used by SSH to 443, and it worked just fine after that.

      Remember your dns queries still go through by regular, unencrypted, means... That 'could' draw attention to whoever is using it. A friend of mine gives access to his SSH server for tunneling for his buddy is Saudi Arabia - just needs to be careful.

  2. All encryption requires permission from the Party by Anonymous+Bullard · · Score: 3, Interesting

    In China and Chinese-ruled territories use or possession of encryption technology without permission from the Chinese Communist Party (aka PRC government) is an offense against the State/CCP. For those forms of encryption that the Party does permit to be used, eg. in online shopping, the Party must have the decryption keys.

    Unlike individuals, companies may be permitted to use encryption without surrendering the keys to the State, but that only happens if the company has been deemed supportive of the Government, or if their presence in China otherwise benefits the State's objectives.

    Since I have some Chinese fenqing (those mindless hordes attacking enemies of State during the Cultural Revolution but now ultra-nationalistic) on my tail this post will probably be modded into oblivion either immediately or eventually...

    Dont even want to be free from the firewall, because it might break their perfect-image that they are so great. They get taught from birth that they live in the best place on Earth and believe this to the fullest. Say anything bad about China towards a Chinese who never left the country and no matter how much evidence you give them and facts you feed them they won't believe it.

    I showed some Chinese websites about Tianmen square, video's, the wikipedia, but all they said that is was fake material made by people who hate China. Some that did know about it was fully on the side of their government and it was just "keeping order".

    Let them take care of it themself if they want to see the truth and not be oppressed but the way it is they want it and like it.

    And if you are a foreigner who needs the a unregulated internet connection, avoid countries like China, maybe if all tourism stops they might considering being less oppressive.

      When I went there everybody knew about it. Try asking them using the term "June Fourth Movement".

      Not everybody refers to it as the "Tiananmen Square Massacre".

  4. My experience in China (Nov. 2008) by nkovacs · · Score: 5, Interesting

    I went to China for vacation November 2008. It was crazy watching the U.S. election from the Yengtze river.

    Being the dork that I am I spent a good chunk of time playing around with the Great Firewall of China. One thing that baffled me was the ease of which I could find "censored" material. For example the wikipedia page for the Tiananmen Square protests was accessible (http://en.wikipedia.org/wiki/Tiananmen_Square_protests_of_1989).

    Searching Google images for "Tiananmen Square" came back with hundreds of tanks, bloody civilians and the like - no different than in the U.S.

    Yet some things were banned. I found that all the free http proxies that I tried were banned. I couldn't get to wikileaks.org. And I couldn't get to the Tor website to download the installer.

    This presents an interesting chicken and egg problem with circumvention software. How do you get the software in the first place if it's source of the software package is censored? I ended up asking a buddy of mine in the U.S. to send me the Tor program via gmail, but not everyone has that option.

    I was only on a very slow 8k/sec connection so at times it was difficult to tell if a site was banned or if it just was really slow. I could only really tell by running a trace route. It would always time out at the same router, presumably the router that bridged between inside and outside China.

    In case anyone is interested here is a tracert going to a banned site.

    I know how it feels like being cyberstalked. Kinda pathetic. But hey, how many of them are really slashdotters caring about the karma stuff? ;)

    As a Chinese, I'm not offended by your viewpoints or position, in fact I quite understand it. However, I remain somewhat skeptic about the factuality of your post because I don't know any established Chinese law regarding the regulation of encryption technology used by individuals (IANAL of course). Can you give me a pointer to some legal material that supports your post? I believe I use encryption of one kind or another on a daily basis (SSH and HTTPS come to mind, as well as the encryption facilities built into bittorrent).

    The French used to have a complete ban on encryption until recently. The UK in the mid-90s were pushing for a key escrow system, where all individuals would have to lodge a copy of their private key with the government, and were very close to succeeding. Instead we now have the RIPA, where you have to disclose your key when asked or go to jail. The only way to safely store a stranger's data on your machine is if it's encrypted and you have no access to the key. Even then ISPs are monitoring what you are downloading.

    There can be plenty of reasons for allowing people to ssh through your machine, but I also would only do it for friends. I did it for one of my friends who wanted to be able to job search during lunch time but didn't want his employer to know he was looking. He wasn't breaking any laws or company rules, but wanted his privacy protected. However, like Idiomatick I would be happy to help anybody that had a good and convincing reason (though they would be in chroot).
