Censorship continues to be a big concern for China

A group of computer experts from the University of Cambridge claims that they are now able to circumvent the censorship mechanism that China uses to block unwanted content from reaching its citizens. Certain words are banned and certain websites are also banned. A user sitting within the country's network will not be able to reach websites for which the government has deemed inappropriate. China itself has defended its right to police the Internet for its citizens many times.

The group of researchers say that China's firewall is based on a a series of Cisco routers and the products work by censoring keywords. When a user wishes to access a websites that's banned, the router returns reset packets to the foreign website, severing the connection -- the data transmission is stopped at the foreign end-point. Using this bit of information on how the Cisco routers work, the researchers were able to find their way around the firewall by creating a system that ignores the reset packets sent by the Chinese routers.

Along with their discovery, the researchers also found that it was possible to create a denial-of-service (DoS) attack from within the firewall using the router's own blocking mechanisms. By masquerading the source IP address of a banned website to one that's within China's network, the researchers are able to ban users from within the network from accessing a Chinese government website for example.

Richard Clayton, spokesperson for the laboratory at the university told reporters that the researchers had reported the findings to the Chinese Computer Emergency Response Team.

For someone as experienced and as well travelled as you claim to be, you don't see very well. There are many differences between US and UK people, customs, laws, and culture; none of which fit your description, IMHO of course.
Then again, I don't suppose the average "Westerner" really sees a big difference between Iran, Iraq, and Saudi Arabia, for instance; when it comes to the people, culture and government.


OTOH, I can't disagree with your original premise that it's a chinese problem, and needs to be addressed by the Chinese.

Well when I said it's the same I wasn't talking about people and customs and traditions. I'm talking about the government and the way it operates. It's not much different from the US way of looking at things and it's mainly because they are looking up to US in more ways then one.

Btw, I'm from Eastern Europe, and I know very well what England is like and other countries and I got to know how US works since I live in the States now.

So yes, I do know more then you think.
