shadowsocks
===========

shadowsocks is a lightweight tunnel proxy which can help you get through firewalls
usage
-----------
Put `server.py` on your server. Edit `server.py`, change the following values:
PORT server port
KEY a password to identify clients
Run `python server.py` on your server. To run it in the background, run `setsid python server.py`.
Put `local.py` on your client machine. Edit `local.py`, change these values:
SERVER your your server ip or hostname
REMOTE_PORT server port
PORT local port
KEY a password, it must be the same as the password of your server
Run `python local.py` on your client machine.
Change proxy settings of your browser into
SOCKS5 127.0.0.1:PORT
