Shadowsocks is good at disguising the traffic as normal HTTP / SOCKS traffic so that it is difficult to detect. Thus, it is relatively fast and power-saving for mobile devices. Each request only forwards one connection and it doesn’t require a connection all the time. The SOCKS5 doesn’t require a handshake other than a TCP connection. Shadowsocks is open-source and can be constantly developed. At the same time, the user’s IP address also becomes the IP address assigned by the VPN. All Internet traffic should travel through this private network to the destination. Using a VPN service means connecting to a private network. VPN is the abbreviation of virtual private network. All data should be transferred through the proxy server. The client communicates with the actual server you are going to access via the proxy server. There is no established private tunnel between the client and the server. Because it has some features that are specially designed to circumvent the GFW. It is based on SOCKS5 proxy but different from a normal proxy. Shadowsocks is designed to bypass the geographical restriction. Differences between a VPN and SS: advantages and disadvantages Users can choose a mode that satisfies their needs. While Global mode reroutes all traffic through the proxy server. If the PAC mode the enabled, the traffic will go through the proxy server when accessing websites blocked by GFW. Preferences preset for some apps still work in this mode. Direct connection mode doesn’t redirect your traffic through the proxy server. Then, your server in Hong Kong that receives your request will visit Google and return the result of this request to you. Generally speaking, when you want to check your Gmail, you can send your request to a server in Hong Kong via SOCKS5 connection. There is no extra processing when the data packet is sent to the proxy server. During this process, your data request won’t pass through a dedicated tunnel. SOCKS5 proxy passes your data request through a connection between you and the proxy server which forwards your request to the destination. So SOCKS proxies are much faster than other application-layer proxies. SOCKS proxies transfer data packets regardless of the transfer protocol. How does Shadowsocks works?īoth SS and SSR work in the same way. SSR had already been forked by many people and there were also new versions based on SSR. This developer dissolved relevant groups and stopped developing Shadowsocks.
#Shadowsocks protocol code
Later on, breakwa11 also removed all code on GitHub due to the threat from a human flesh search. So, breakwa11 created ShadowsocksR on the base of Shadowsocks, which supported obfuscation. SSR (ShadowsocksR): After what happened to Shadowsocks in 2015, another developer, breakwa11 claimed that SS is easy to be detected by the GFW.
#Shadowsocks protocol update
As a result, clowwindy deleted code on Github and promised not to participate in any maintenance or update of Shadowsocks. In 2015, however, the creator was under the pressure from the Chinese government. Thus, clowwindy shared it with others on GitHub.
Then, the developer thought it was useful to unblock websites because it is hard to be detected while ensures a fast Internet connection. SS (Shadowsocks): It was created by clowwindy to get past the GFW in 2012. Whether the communication between you and the VPN is encrypted or not depends on the VPN protocol it uses.
Your Internet access goes through this private network. When you connect to a VPN, you’re actually connecting to a private network. A VPN, known as a virtual private network, encrypts your communication online. It is widely used in enterprise and university networks. On the other hand, it builds a private network to transfer data at the network layer. On the one hand, a VPN unblocks websites, which is exactly what Shadowsocks do for you. Differences between a VPN and SS: advantages and disadvantages.Since it’s easy to feel confused about Shadowsocks and a VPN, I would like to make an introduction from the following four parts: Shadowsocks, or SS for short, became popular among Chinese netizens. In 2012, a Chinese created Shadowsocks to circumvent Internet censorship in China and shared it on GitHub. VPN is a commonly used tool in China to help them access blocked content and services. Due to the Great Firewall of China, Chinese people need to bypass restrictions to use Google services, post on Facebook, stream videos on YouTube and so on.
