$ ./configure && make
$ make install

Usage on server :
Usage :
$ ssserver -p <port> -k <password> -m rc4-md5
To run in the background :
$ sudo ssserver -p <port> -k <password> -m rc4-md5 --user nobody -d start
To stop:
$ sudo ssserver -d stop
To check the log :
$ sudo less /var/log/shadowsocks.log
Usage on client
Create a file config.json. example config :
{
"server":"<your server ip",
"server_port":<your server port>,
"local_address": "127.0.0.1",
"local_port":<your local port>,
"password":"<your password>",
"timeout":300,
"method":"rc4-md5",
"fast_open": false
}
Save and running this command in same directory:
$ sslocal
last step is config your browser proxy to sock5 listen to 127.0.0.1 and local port
In firefox go to Preferences -> Network Tab -> Settings -> Choose Manual Proxy and fill in Sock host form (fill port form depend of your local port config.json.
Firefox Proxy settings
We also can use shadowsocs in another client.
Conclusion
ShadowSocks asynchronous I/O technology makes browsing the Internet faster than OpenVPN but that in the end speed will depend on the server load and ping even if the protocol is light on resources. The greatest benefit of using ShadowSocks is that it is easy to set up your own ShadowSocks server on a cheap VPS. Notice that this program has been designed as an anticensorship tool and not to make you anonymous on the Internet. Happy Surfing !
