This is a port of shadowsocks.

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

Dependencies

  • libcrypto (OpenSSL)
  • libsodium

Usage

Install from crates.io:

cargo install shadowsocks-rust

then you can find sslocal and ssserver in $CARGO_HOME/bin.

or you can also build with Cargo:

cargo build

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

Read Cargo.toml for more details.

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 an 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

cargo run --bin sslocal -- -c config.json
cargo run --bin ssserver -- -c config.json

List all available arguments with -h.

Supported Ciphers

  • aes-128-cfb, aes-128-cfb1, aes-128-cfb8, aes-128-cfb128
  • aes-256-cfb, aes-256-cfb1, aes-256-cfb8, aes-256-cfb128
  • rc4, rc4-md5
  • chacha20, salsa20
  • dummy (No encryption, just for debugging)
  • aes-128-gcm, aes-192-gcm, aes-256-gcm

Useful Tools

  1. ssurl is for encoding and decoding ShadowSocks URLs. Example: ss://YWVzLTI1Ni1jZmI6aGVsbG93b3JsZF9mdWNrQDEyNy4wLjAuMTo4Mzg4

Notes

It supports the following features:

  • Socks5 CONNECT command
  • UDP ASSOCIATE command (partial)
  • HTTP Proxy protocol Deprecated, use privoxy instead.
  • Various crypto algorithms
  • Load balancing (multiple servers)

TODO

  • Documentation
  • Extend configuration format
  • 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)
  • Windows support. (Depending on mio and coio-rs)
  • Build with stable. (Depending on coio)
  • Support HTTP Proxy protocol (it is easy to use another tools to convert HTTP proxy protocol to Socks5, like privoxy)
  • One-time Auth. (Already deprecated according to Shadowsocks' community)
  • AEAD ciphers. (proposed in SIP004, still under discussion)
