Behind China's Great Firewall

DigitalDame2 writes "In light of the upcoming Olympic Games in Beijing, more scrutiny is being placed on China's Web-filtering practices. In May, China's technology minister, Wan Gang, told Reuters China he would 'guarantee as much [access] as possible,' defending Web limitations as necessary to protect the country's citizens. Truly understanding this cat-and-mouse game means taking a close look at what exactly the government filters out, how the Great Firewall works, and how others have found ways around it."

Firewall tech

[mactard]

I honestly want to see pictures of that thing. I mean, every single packet that goes in and out of China goes through a giant box. That thing has to be huge to filter any sort of serious bandwidth.

Re:Firewall tech

[jeffmeden]

Who's to say it's not distributed among many (possibly hundreds) of gateways. It seems a bit impractical to think that China's internet connectivity funnels through one single geographical point, much less through one physical device. That, or you were being sarcastic...

Re:Firewall tech

[ricebowl]

I have a feeling that, with the censorship being taken mostly at the ISP level in order to avoid governmental scrutiny/sanctions, that it occurs at the ISP's servers. So rather than any one piece of hardware doing all the work there's hundreds (I presume, I have no idea how many ISPs operate inside of China, though I'd expect there to be quite a few).

Re:Firewall tech

[OeLeWaPpErKe]

Actually just about every ISP outside of america has internet filters in place (even those in the supposed "free" the Netherlands).

For starters if a country has 50% muslims, you can assume it filters the internet.

If a country is not free in speech (and that qualifies quite a bit more countries than you'd think, including all European countries), then they have either ISP or judicial filters, that in practice means their isp's filter.

Even Canada, matter-of-factly has ISP filters. Let's FIRST fix Canada, then we should move on to the UK or so, where there was one site that qualified as hate speech for advocacy against Blair.

I don't think what China does is good, I just question singling out China. And there are many countries where you actually might make a difference.

Besides slashdot users where by far in favor of sensoring stuff if it endangered people's safety, like when death threats were made by muslims about wilder's film. That was in the UK.

Let's start there. Then, AFTER that, and all other European countries and after Canada, then we can move Canada. What point is there in saying as a non-free country to China that they should be free ?

Re:

[Stewie241]

I think the point was that there is no need for ISP filters if people are being fined by a human rights commission for speaking freely.

This saves the ISPs effort - they don't have to bother, because threats of legal action will scare people into silence.

I don't know the facts - just clarifying his argument.

Re:

But to say that a human rights commission isn't needed at all because we can go shopping on days when Christians traditionally took the day off work is ludicrous.

Don't disagree... Would be interested in seeing how the HRC handles issues of free speech. I really appreciate the freedom I have to agree or disagree with the government and current public opinion.

I'm not saying that it's right for people to be censored because they offend people, but there is a lot of room for improvement in terms of human rights here (and elsewhere).

Absolutely. Though human rights are by nature a limited resource - if you give one human too many rights it impedes on the rights of another.

I would also contend that, based on the sorts of websites I can access and the sort of bigotry I can find that isn't censored, the human rights commission is extremely ineffective at silencing the sorts of people who would make negative statements about minority groups online. The grandparent post didn't provide what I would consider a particularly reliable website for information so I don't really know if the issue is just censorship or if there's something else to it (i.e. if the author is attempting to incite violence against a group, should they still be allowed to do so even if it's just talking?).

This isn't about right-wing compartmentalized websites... if you are only allowed to speak freely if you are a small time website, isn't that marginalization?

Yes, and no. According to Erik Laykin of Navigant Consulting there are 3 points that connect China to the interweb (I think maybe Beijing, Shanghai, and Guangzho.) The Chinese government is indeed spanning all 3. But considering that you have traffic for over 200 million people flowing through those 3 points, there are hundreds if not thousands of devices scattered all over the country to make up the Golden Shield. Interestingly, many of those devices of censorship were supplied by Cisco, Oracle, Microsoft, etc. Long live capitalism!

FTA:

Even the good old U.S. of A. has restricted access in some cases. In May 2007, just a few weeks after placing restrictions on soldiers' blogs, the Department of Defense blocked access for soldiers to 13 "social networking and recreational" Web sites such as MySpace and YouTube, claiming that they took up too much bandwidth and presented operational risks. Ultimately, the ban severely limited the ability of soldiers overseas to communicate with loved ones at home, especially since the sites couldn't be accessed throughout much of Iraq and Afghanistan.

I'm not sure once can draw a moral equivelancy between the Army blocking what soldiers do over Army internet connections from war-zones and the Chinese blocking internet access for regular citizens.

Until the USA starts filtering my access to the BBC, I don't really know why they even brought that up -- its just like workplace filtering at any other job.

Not just Slashot users, but Chinese in general. I watched a news program or documentary recently that covered the subject, and it turns out the Chinese, the young and college educated particularly, exhibit the same reaction.

It turns out that, and I'm generalising here, the Chinese, if they don't "like it that way". have few objections to strong government control. For a westerner that might be hard to fathom, but I think it's unfair to dismiss their preferences as absurd or characterise them as the result of some sort of brainwashing.

What shouldn't be hard to fathom is that for someone who's Chinese, China is their country. Last I checked, national pride is a universal phenomenon, and treading on other's sense of identity or pride, however enlightened or well-intentioned, is always bad form and inevitably leads to conflict.

How it works.

[physman_wiu]

In America, the Internet was originally designed to be free of choke points, so that each packet of information could be routed quickly around any temporary obstruction. In China, the Internet came with choke points built in. Even now, virtually all Internet contact between China and the rest of the world is routed through a very small number of fiber-optic cables that enter the country at one of three points: the Beijing-Qingdao-Tianjin area in the north, where cables come in from Japan; Shanghai on the central coast, where they also come from Japan; and Guangzhou in the south, where they come from Hong Kong. (A few places in China have Internet service via satellite, but that is both expensive and slow. Other lines run across Central Asia to Russia but carry little traffic.) In late 2006, Internet users in China were reminded just how important these choke points are when a seabed earthquake near Taiwan cut some major cables serving the country. It took months before international transmissions to and from most of China regained even their pre-quake speed, such as it was.

Thus Chinese authorities can easily do something that would be harder in most developed countries: physically monitor all traffic into or out of the country. They do so by installing at each of these few 'international gateways' a device called a 'tapper' or 'network sniffer,' which can mirror every packet of data going in or out. This involves mirroring in both a figurative and a literal sense. 'Mirroring' is the term for normal copying or backup operations, and in this case real though extremely small mirrors are employed. Information travels along fiber-optic cables as little pulses of light, and as these travel through the Chinese gateway routers, numerous tiny mirrors bounce reflections of them to a separate set of 'Golden Shield' computers.Here the term's creepiness is appropriate. As the other routers and servers (short for file servers, which are essentially very large-capacity computers) that make up the Internet do their best to get the packet where it's supposed to go, China's own surveillance computers are looking over the same information to see whether it should be stopped.

Think again of the real importance of the Great Firewall. Does the Chinese government really care if a citizen can look up the Tiananmen Square entry on Wikipedia? Of course not. Anyone who wants that information will get it-by using a proxy server or VPN, by e-mailing to a friend overseas, even by looking at the surprisingly broad array of foreign magazines that arrive, uncensored, in Chinese public libraries.

What the government cares about is making the quest for information just enough of a nuisance that people generally won't bother. Most Chinese people, like most Americans, are interested mainly in their own country. All around them is more information about China and things Chinese than they could possibly take in. The newsstands are bulging with papers and countless glossy magazines. The bookstores are big, well stocked, and full of patrons, and so are the public libraries. Video stores, with pirated versions of anything. Lots of TV channels. And of course the Internet, where sites in Chinese and about China constantly proliferate. When this much is available inside the Great Firewall, why go to the expense and bother, or incur the possible risk, of trying to look outside?

All the technology employed by the Golden Shield, all the marvelous mirrors that help build the Great Firewallâ"these and other modern achievements matter mainly for an old-fashioned and pre-technological reason. By making the search for external information a nuisance, they drive Chinese people back to an environment in which familiar tools of social control come into play.

http://www.theatlantic.com/doc/200803/chinese-firewall [theatlantic.com] So they are going to let certain IPs get anything they want. So it won't even seem like there is a 'Golden Shield' to most foreigners that visit China for the Olympics.

Terrible

[gigne]

Ugh. A terrible article which you could summarise in one sentence..
"Use a VPN or proxy if you want to use the internet without fear or restriction."

I was hoping for more detailed information on the operational hardware involved in filtering a country, not confirmation it happens, which is already widely known.

Don't worry.

[physman_wiu]

I really think that they feel they have a reason to censor the net for places where most foreigners are going to be hanging out during the Olympics. Most of those places aren't going to have your average Chinese citizen just looking for a way to get around the firewall.

The government cares about their 'face' and they aren't going to want to the rest of the world seeing what they do control. They'll just let those places have access and then after the Olympics, restrict it again.

blocked sites

[pangloss]

Some of the sites that I know to be blocked:

Blogger
Blogspot
Flickr (only the photo serving subdomains)
Typepad
Wordpress

Formerly blocked, but now open:
Wikipedia
BBC News

As far as I'm aware, the blocks on the blog-related sites are domain or netblock level--not the result of keyword or content-level filtering.

Defend citizens

...necessary to protect the country's citizens.

It's not protecting Chinese citizens that's the problem. It's protecting the rest of the world from the Chinese citizens [slashdot.org] that concerns me.

Foreigner Have It the Wrong Way Around

[mutantcamel]

Largely, amongst the well educated, English speaking professional Chinese people that I meet (I've lived in China for 2 years) who are in their mid/late 20's, the reverence and respect they havefor the CCP is probably more fervant tham amongst the older generation who helped to found the People's Republic. The patriostism gives way to nationalism, and I find some of my friends who I had respected as having been able to form their own intelligent opinions on the world at large have descended into China-loving, French-hating lunatics.

Westerners have to try to understand that the generation that's in it's mid-late 20's owe their standard of living and level income to the Communist Party, they and look to the party members for moral guidance. Propaganda, even on the "international" CCTV-9 has reached an all time high with wall to wall interview of people who have lost everything praising the work of the government.

When it comes to Internet censorship, it's largely a joke. Websites can be overcome with any number of web proxies, and even if you can't get to the porn that you want, you can go to the local computer markets in Zhongguancun or Chaoyangmen, where you'll be offered "DVD sex movies". The BBC had been unblocked, but blocks are still in place for servers on Flicker and on Livejournal and Blogspot.

The government here is rather sneaky. They don't say that they actively and specifically filter websites, rather, they ask ISPs to self-censor and these ISP's face heavy fines for allowing undesirable content through. This is the reason that websites that are accessbile in Shanghai aren't accessible in Beijing or other parts of China.

A good project to keep an eye on is Concept Doppler, which has a list of what keywords and phrases are filtered by the GFW. What is interesting is that of all the tests that CD team performed, a certain number of the phrases did managed to get through the filter, showing that the GFW doesn't filter everything all the time, but filters some most of the time, which creates the impression that everything is filtered, and, ultimately, keeps people scared.

Re:

[Free the Cowards]

That's interesting, because my impression has been quite different. From what I've seen, the people that age are largely apolitical. Not anti-Communist at all, they just don't care. Largely they think the government is doing a decent job, but with no strong feelings on the subject. Personally I think this attitude is completely understandable. The current government is doing a fairly decent job of things overall, and why would you care about politics if you can't affect them in any way?

Re:

[Free the Cowards]

I have seen the same thing, I just don't consider it political.

Look at people who are interested in politics in the US. They're not talking about what countries we like or hate. That's redneck talk. People who are truly interested in politics talk about personalitie,s about who they're going to vote for, about policies, whether a law will have the intended effect, what industries will be helped or hurt by an attempt at protectionism, strategies for blocking or passing legislation, etc. That's politics, and

[Anonymous Coward]

I traveled from Shanghai to Kunming and then north into the Tibetan Autonomous Region (TAR) last year. I was in China for a total of 28 days. I had my Linux-based laptop with me the entire time and never had a problem locating an open wireless access point. Nor did I have any problem using SSH to connect to my boxes back in the states. I use my own SquirrelMail based web mail via SSL, and only once in 28 days did I find myself blocked from that stateside box. Their firewall leaks like a sieve.

GFW reflects gap of generations in China

[pythonist]

Having gained my four year college education in University of Science and Tech. of China, I have some experience on GFW. Chinese people's attitude toward GFW reflects gap of old and young generations.

Almost all young Chinese, me included, think GFW is totally stupid and the people who are in charge of the blocking have pig brains. why?

1. CNN/BBS/FalunGong/TibetGIE should not be blocked since nobody in China reads them.

2. Some irrelevant websites such as sourceforge used to be blocked.

However, most of old pe

dear han ultranationalists:

[circletimessquare]

china is obviously a great power in this world. when you are a great power, you get criticized. with great power, this kind of criticism is a natural occurence

a true great man can take lots of criticism in stride. an immature powerless man meanwhile freaks out every time someone suggests the slightest negative thing about him. it shows a lack of confidence, an insecurity

han ultranationists: do you believe that china is a great power? if you do, then start acting as that great power status dictates: have more confidence. china will be criticized more and more every year since it is so powerful now. if you cannot handle that criticism, then you are in danger of destroying your own greatness with your own insecure behavior

to defeat the creation of insecure people in china, you should foster a healthy amount of internal dissent and self-critical thinking in china. if you do not, if you censor anything that remotely criticizes the chinese government or the chinese nation, then what you do is make the chinese people permanent children. you incubate chinese who are unable to handle criticism without freaking out in insecurity and a lack of confidence

and thereby diminishing the greatness of china

china is a great nation. i believe that as an american. so start acting like a great nation, and grow some thicker skin when foreigners criticize china. being criticized is a natural product of being powerful. get used to it. believe me, as an american, i know something about being criticized on the world stage! and mostly, i just shrug it off. you should to

Wait a minute

[Randall311]

TFA says that censorship is taking place in the US, with the DoD blocking or restricting access to social networking sites such as MySpace and YouTube that are bandwidth intensive and presented operational risks. This seems perfectly reasonable to me. This is NOT censorship. There are other ways of communicating with friends that take up less bandwidth and are operationally secure, such as email. Plenty of work places filter their internet access to employees, and that is not censorship either. There i

[corychristison]

Is it just me or does there seem to be an article of or having to do with "China'a Great Firewall" every few weeks?

I, for some reason, keep thinking that I have seen this article title many, many times before.

Am I going crazy?
