Run ``ssserver -c /etc/shadowsocks.json`` on your server. To run it in
the background, `use
supervisor <https://github.com/clowwindy/shadowsocks/wiki/Configure-Shadowsocks-with-Supervisor>`__.

On your client machine, run ``sslocal -c /etc/shadowsocks.json``.

Change the proxy settings in your browser to

::

    protocol: socks5
    hostname: 127.0.0.1
    port:     your local_port

**Notice: If you want to use encryption methods other than "table",
please install M2Crypto (See Encryption Section).**

It's recommended to use shadowsocks with AutoProxy or Proxy
SwitchySharp.

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

Salsa20
-------

Salsa20 is a fast stream cipher.

Use "salsa20-ctr" in shadowsocks.json.

And install these packages:

Debian / Ubuntu:
^^^^^^^^^^^^^^^^

::

    apt-get install python-numpy
    pip install salsa20
