shadowsocks-rust

This is a port of shadowsocks.

shadowsocks is a fast tunnel proxy that helps you bypass firewalls.

Currently developing and testing with rust-nightly

Dependences

libcrypto (OpenSSL)
Rust nightly
Cargo

Usage

Build with Cargo:

cargo build

Then sslocal and ssserver will appear in ./target, it works similarly as the two binaries of the official shadowsocks' implementation.

Enable more crypto algorithms by passing the name cipher-[name] via command line argument --features

cargo build --features "cipher-aes-ctr"

Read Cargo.toml for more details.

Required libsodium and libcrypto by default.

Getting Started

Create a shadowsocks' configuration file. 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"
}

Detailed explaination could be found in shadowsocks' documentation.

In shadowsocks-rust, we also have a extended configuration file format, which is able to define more than one servers:

{
    "servers": [
        {
            "address": "127.0.0.1",
            "port": 1080,
            "password": "hello-world",
            "method": "bf-cfb",
            "timeout": 300,
        },
        {
            "address": "127.0.0.1",
            "port": 1081,
            "password": "hello-kitty",
            "method": "aes-128-cfb"
        }
    ],
    "local_port": 8388,
    "local_address": "127.0.0.1"
}

The sslocal will use a load balancing algorithm to dispatch packages to all servers.

Start local and server shadowsocks with

sslocal -c config.json
ssserver -c config.json

List all available arguments with -h.

Default log level is error, override it by setting environment variable RUST_LOG. Please refer to log crate for more detail.

Notes

Still under developing and waiting for the final release of rust-1.0.

It supports the following features:

CONNECT, UDP ASSOCIATE commands
Crypto algorithms defined in Cargo.toml
Load balancing

The socks5_cli.rs under the root directory is a Socks5 client for testing.

TODO

Documentation
BIND command (Maybe no one will use it)
Socks5 authentication
~~Extend configuration format~~
Fully testing on servers
Performance testing and improvement
User management
PAC
Improved logging format (waiting for the new official log crate)
Support more ciphers without depending on libcrypto (waiting for an acceptable Rust crypto lib implementation)
