shadowsocks-rust

Build Status License crates.io Release

This is a port of shadowsocks.

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

Dependencies

  • libcrypto (OpenSSL)
  • libsodium >= 1.0.7 (Required for ciphers that are provided by libsodium)

Build & Install

crates.io

Install from crates.io:

cargo install shadowsocks-rust

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

Download release

Requirements:

  • Linux x86_64

Download static-linked build here.

Build from source

Use cargo to build.

cargo build --release

NOTE: If you haven't installed the correct version of libsodium in your system, you can set a environment variable SODIUM_BUILD_STATIC=yes to let libsodium-ffi to build libsodium from source, which requires you to have build tools (including GCC, libtools, etc.) installed.

SODIUM_BUILD_STATIC=yes cargo build --release

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

make install TARGET=release

Then sslocal, ssserver and ssurl will be installed in /usr/local/bin (variable PREFIX).

For Windows users, if you have encountered any problem in building, check and discuss in #102.

Build standalone binaries

Requirements:

  • Docker
./build/build-release

Then sslocal, ssserver and ssurl will be packaged in

  • ./build/shadowsocks-latest-release.x86_64-unknown-linux-musl.tar.gz
  • ./build/shadowsocks-latest-release.x86_64-unknown-linux-musl.tar.xz

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 If you Build it with Makefile:

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

If you Build it with Cargo:

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

List all available arguments with -h.

Usage

Local client

# Read local client configuration from file
$ sslocal -c /path/to/shadowsocks.json

# Pass all parameters via command line
$ sslocal -b "127.0.0.1:1080" -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty" --plugin "obfs-local" --plugin-opts "obfs=tls"

# Pass server with SIP002 URL
$ sslocal -b "127.0.0.1:1080" --server-url "ss://YWVzLTI1Ni1nY206cGFzc3dvcmQ@127.0.0.1:8388/?plugin=obfs-local%3Bobfs%3Dtls"

Server

# Read server configuration from file
$ ssserver -c /path/to/shadowsocks.json

# Pass all parameters via command line
$ ssserver -s "[::]:8388" -m "aes-256-gcm" -k "hello-kitty" --plugin "obfs-server" --plugin-opts "obfs=tls"

DNS Local server

# Read configuration from file
$ ssdns -c /path/to/shadowsocks.json

# Pass all parameters via command line
$ ssdns -s "[::]:8388" -m "aes-256-gcm" -k "hello-kitty" --dns "8.8.8.8:53"

For DNS relay server, you can set remote DNS server in configuration file with dns key in root object.

{
    "dns": "8.8.8.8"
}

Supported Ciphers

Stream 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, chacha20-ietf
  • plain (No encryption, just for debugging)

AEAD Ciphers

  • aes-128-gcm, aes-256-gcm
  • chacha20-ietf-poly1305, xchacha20-ietf-poly1305
  • aes-128-pmac-siv, aes-256-pmac-siv (experimental)

Useful Tools

  1. ssurl is for encoding and decoding ShadowSocks URLs (SIP002). Example:

    ss://YWVzLTI1Ni1jZmI6cGFzc3dvcmQ@127.0.0.1:8388/?plugin=obfs-local%3Bobfs%3Dhttp%3Bobfs-host%3Dwww.baidu.com
    

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)
  • SIP004 AEAD ciphers
  • SIP003 Plugins
  • SIP002 Extension ss URLs

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)
