shadowsocks-go is a lightweight tunnel proxy which can help you get through firewalls. It is a port of shadowsocks.
The protocol is compatible with the origin shadowsocks (if both have been upgraded to the latest version).
server_password option syntax changed in 0.6.2, the client now connects to servers in the order specified in the config.
Please develop on the latest develop branch if you want to send pull request.
Compiled client binaries can be download here. (All compiled with cgo disabled, except the mac version.)
You can also install from source (assume you have go installed):
# on server go get github.com/shadowsocks/shadowsocks-go/cmd/shadowsocks-server # on client go get github.com/shadowsocks/shadowsocks-go/cmd/shadowsocks-local
It's recommended to disable cgo when compiling shadowsocks-go. This will prevent the go runtime from creating too many threads for dns lookup.
Both the server and client program will look for
config.json in the current directory. You can use
-c option to specify another configuration file.

About encryption methods
AES is recommended for shadowsocks-go. Intel AES Instruction Set will be used if available and can make encryption/decryption very fast. To be more specific,
aes-128-cfb is recommended as it is faster and secure enough.
rc4 and table encryption methods are deprecated because they are not secure.
Command line options
Command line options can override settings from configuration files. Use
-h option to see all available options.
shadowsocks-local -s server_address -p server_port -k password -m aes-128-cfb -c config.json -b local_address -l local_port shadowsocks-server -p server_port -k password -m aes-128-cfb -c config.json -t timeout
-d option to enable debug message.
Use multiple servers on client
server_password specify multiple server and password, server should be in the form of host:port
Here's a sample configuration
server_password, client program will ignore
Servers are chosen in the order specified in the config. If a server can't be connected (connection failure), the client will try the next one. (Client will retry failed server with some probability to discover server recovery.)
Multiple users with different passwords on server
The server can support users with different passwords. Each user will be served by a unique port. Use the following options on the server for such setup:
port_password specify multiple ports and passwords to support multiple users
Here's a sample configuration
port_password, server program will ignore
Update port password for a running server
Edit the config file used to start the server, then send
SIGHUP to the server process.
Note to OpenVZ users
Use OpenVZ VM that supports vswap. Otherwise, the OS will incorrectly account much more memory than actually used. shadowsocks-go on OpenVZ VM with vswap takes about 3MB memory after startup. (Refer to this issue for more details.)
If vswap is not an option and memory usage is a problem for you, try shadowsocks-libev.
