This year Chinese government deepened a attack on virtual private networks (VPNs)-tools which help online surfers inside the mainland get the open, uncensored internet. Whilst not a blanket ban, the latest limitations are moving the services out of their legal grey area and further all the way to a black one. In July only, one such made-in-China VPN unexpectedly ceased operations, The apple company cleaned up and removed many VPN software applications from its China-facing iphone app store, and a certain amount of worldwide hotels stopped providing VPN services as part of their in-house wireless network.

Nonetheless the bodies was fighting VPN use some time before the most recent push. From the moment president Xi Jinping took office in the year 2012, activating a VPN in China has been a ongoing nightmare - speeds are poor, and internet often falls. Mainly before major political events (like this year's upcoming party congress in October), it's not unusual for connections to fall instantaneously, or not even form at all.

In response to all these situations, Chinese tech-savvy coders have already been turning to an extra, lesser-known software to access the wide open net. It's often called Shadowsocks, and it's an open-source proxy designed for the targeted purpose of leaping Chinese GFW. While the government has made efforts to restrain its distribution, it is likely to keep tough to control.

How is Shadowsocks more advanced than a VPN?

To discover how Shadowsocks runs, we will have to get a tad into the cyberweeds. Shadowsocks is based on a technique referred to proxying. Proxying grew popular in China during the beginning of the Great Firewall - before it was truly "great." In this setup, before connecting to the wider internet, you first connect with a computer other than your own. This other computer is called a "proxy server." If you use a proxy, your whole traffic is forwarded first through the proxy server, which can be positioned anywhere. So even in the event you are in China, your proxy server in Australia can effectively connect with Google, Facebook, etc.

But the Great Firewall has since grown more powerful. In the present day, even if you have a proxy server in Australia, the GFW can certainly detect and prohibit traffic it doesn't like from that server. It still realizes you're requesting packets from Google-you're just using a bit of an odd route for it. That's where Shadowsocks comes in. It produces an encrypted link between the Shadowsocks client on your local PC and the one running on your proxy server, employing an open-source internet protocol termed SOCKS5.

How is this distinctive from a VPN? VPNs also get the job done by re-routing and encrypting data. Butmost of the people who employ them in China use one of a few big service providers. That makes it easy for the authorities to identify those service providers and then hinder traffic from them. And VPNs ordinarily make use of one of some well-known internet protocols, which explain to computer systems how to converse with each other over the internet. Chinese censors have already been able to utilize machine learning to find "fingerprints" that distinguish traffic from VPNs with such protocols. These techniques don't succeed so well on Shadowsocks, because it is a less centralized system.


Each and every Shadowsocks user establishes his own proxy connection, thus every one looks a bit not the same as the outside. Accordingly, identifying this traffic is more complicated for the GFW-this means, through Shadowsocks, it is relatively complicated for the firewall to identify traffic heading to an innocuous music video or a economic news article from traffic going to Google or other site blocked in China.

Leo Weese, a Hong Kong-based privacy advocate, likens VPNs to a proficient freight forwarder, and Shadowsocks to having a product shipped to a mate who then re-addresses the item to the real intended receiver before putting it back in the mail. The former way is far more money-making as a business venture, but less complicated for government to identify and prohibited. The latter is make shift, but much more private.

What's more, tech-savvy Shadowsocks users often modify their configuration settings, which makes it even harder for the GFW to uncover them.

"People take advantage of VPNs to create inter-company links, to set up a safe network. It was not intended for the circumvention of content censorship," says Larry Salibra, a Hong Kong-based privacy supporter. With Shadowsocks, he adds, "Anyone is able to set up it to look like their own thing. That way everybody's not employing the same protocol."

Calling all of the programmers

If you happen to be a luddite, you can likely have a hard time deploying Shadowsocks. One standard method to work with it calls for renting out a virtual private server (VPS) placed outside of China and effective at using Shadowsocks. Subsequently users must log on to the server making use of their computer's terminal, and deploy the Shadowsocks code. Next, employing a Shadowsocks client software package (you'll find so many, both paid and free), users input the server IP address and password and connect to the server. Following that, they are able to visit the internet readily.

Shadowsocks is sometimes tough to build as it originated as a for-coders, by-coders application. The computer program very first hit the general public in 2012 through Github, when a coder utilizing the pseudonym "Clowwindy" posted it to the code repository. Word-of-mouth pass on amongst other Chinese developers, and in addition on Twitter, which has always been a base for anti-firewall Chinese programmers. A online community shaped around Shadowsocks. Individuals at several of the world's largest tech corporations-both Chinese and intercontinental-work with each other in their leisure time to sustain the software's code. Developers have created 3rd-party apps to run it, each offering various custom capabilities.

"Shadowsocks is a brilliant innovation...- So far, there is still no signs that it can be recognized and be ceased by the GFW."

One such engineer is the author at the rear of Potatso, a Shadowsocks client for Apple inc iOS. In Suzhou, China and hired at a US-based software program corporation, he got bothered at the firewall's block on Google and Github (the 2nd is blocked irregularly), each of which he counted on to code for job. He created Potatso during night time and weekends out of frustration with other Shadowsocks clients, and at last place it in the iphone app store.

"Shadowsocks is a terrific invention," he says, requiring to remain mysterious. "Until now, there's still no evidence that it can be determined and get discontinued by the GFW."

Shadowsocks mightn't be the "ideal weapon" to prevail over the GFW entirely. But it will probably lie in wait after dark for a long time.
