A fast tunnel proxy that help you get through firewalls

Project description

PyPI version Build Status

A fast tunnel proxy that helps you bypass firewalls.



You’ll have a client on your local side, and setup a server on a remote server.


Debian / Ubuntu:

apt-get install python-pip
pip install shadowsocks

Or simply apt-get install shadowsocks if you have Debian sid in your source list.


yum install python-setuptools
easy_install pip
pip install shadowsocks


Download OpenSSL for Windows and install. Then install shadowsocks via easy_install and pip as Linux. If you don’t know how to use them, you can directly download the package, and use python shadowsocks/ instead of ssserver command below.


On your server create a config file /etc/shadowsocks.json. Example:

    "local_address": "",
    "fast_open": false,
    "workers": 1

Explanation of the fields:

Name Explanation
server the address your server listens
server_port server port
local_address the address your local listens
local_port local port
password password used for encryption
timeout in seconds
method default: “aes-256-cfb”, see Encryption
fast_open use TCP_FASTOPEN, true / false
workers number of workers, available on Unix/Linux

Run ssserver -c /etc/shadowsocks.json on your server. To run it in the background, use Supervisor.

On your client machine, use the same configuration as your server, and start your client.

If you use Chrome, it’s recommended to use SwitchySharp. Change the proxy settings to

protocol: socks5
port:     your local_port

If you can’t install SwitchySharp, you can launch Chrome with the following arguments to force Chrome to use the proxy:

Chrome.exe --proxy-server="socks5://" --host-resolver-rules="MAP * , EXCLUDE localhost"

If you can’t even download Chrome, find a friend to download a Chrome Standalone installer for you.

Command line args

You can use args to override settings from config.json.

sslocal -s server_name -p server_port -l local_port -k password -m bf-cfb
ssserver -p server_port -k password -m bf-cfb --workers 2
ssserver -c /etc/shadowsocks/config.json

List all available args with -h.
