Install
-------

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

### Client

* [Windows] / [OS X]
* [Android] / [iOS]
* [OpenWRT]

### 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.

#### CentOS:

    yum install python-setuptools
    easy_install pip
    pip install shadowsocks

#### Windows:

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/server.py`
instead of `ssserver` command below.

Configuration
-------------

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

    {
        "server":"my_server_ip",
        "server_port":8388,
        "local_address": "127.0.0.1",
        "local_port":1080,
        "password":"mypassword",
        "timeout":300,
        "method":"aes-256-cfb",
        "fast_open": false
    }

On your server:

To run in the foreground:

    ssserver -c /etc/shadowsocks.json

To run in the background:

    ssserver -c /etc/shadowsocks.json -d start
    ssserver -c /etc/shadowsocks.json -d stop

On your client machine, use the same configuration as your server. Check the
README of your client for more information.

Command Line Options
--------------------

Check the options via `-h`.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 -d start --pid-file=/tmp/shadowsocks.pid
    ssserver -c /etc/shadowsocks/config.json -d stop --pid-file=/tmp/shadowsocks.pid
