Circumventing Censorship?

Black Swan

Met a student visiting from the People's Republic of China (PRC) yesterday while sipping a java in the local coffeehouse. She's taking a few classes over the summer at a local university, before returning to her homeland. She was amazed at what you could access on the web in the States, claiming that there was government censorship in PRC.

We were uncertain as to how the government may be implementing web censorship, so we have a few questions for the IT experts, hackers, and crackers on boards.ie (of course realising that they all wear white hats, believe in freedom of speech, and are the good guys:cool:):

• Do you think they may just be URL filtering? If so, she could work around that by just using the IP addresses rather than the domain names?
• If they are IP address filtering too, could she work around that by converting the IP into its binary number, stringing them together, then converting them into the decimal equivalent?
• If they are content filtering too, is she s*** out of luck? Any hacks you can suggest?
• There is a concern that she may come up on their radar, so a lot of trial-and-error hacking may be out of the question once back in the PRC.
• Comments? Suggestions?

Good technical information on how it might work

Having used computers in china and soon ill be moving there more permanently.

Best advice is don't fook about in the first place.

Its not a country that you want to be at this kind of stuff unless you know what your doing and even then id be very careful.

They really don't like anything that could be considered against the party line. So i would suggest no one give her any half baked advice as that may get her in a whole world of poo.

I know this is not the advice you want to hear but China has a very different attitude and culture to here that is difficult for us to understand.

Great Firewall of China!, it looks like Australia is now going down the same route...

Just tunnel everything over SSH?

tor is also an option but you run a big big risk there as an exit node

Make sure she keeps her mouth shut as well if you help her with an ssh tunnel.

The party line is also what your average joe on the street believes.

Personally I would find TOR too slow.

I haven't used it for a long time but in the past the main problem I had was the speed.
