Build Status Build status License crates.io dependency status Release CircleCI

This is a port of shadowsocks.

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

Dependencies

Build & Install

Optional Features

Default features: ["sodium", "rc4", "aes-cfb", "aes-ctr", "trust-dns"].

NOTE: To disable dependency of OpenSSL, just disable feature rc4, aes-cfb, aes-ctr, camellia-cfb.

crates.io

Install from crates.io:

bash cargo install shadowsocks-rust

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

Download release

Requirements:

Download static-linked build here.

Nightly builds could be downloaded from CircleCI.

Build from source

Use cargo to build.

bash cargo build --release

NOTE: libsodium-sys builds and links statically to the libsodium in its package. Here are some useful environment variables for customizing build processes:

bash SODIUM_USE_PKG_CONFIG=1 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.

bash make install TARGET=release

Then sslocal, ssserver, sstunnel 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:

bash ./build/build-release

Then sslocal, ssserver, sstunnel and ssurl will be packaged in

Read Cargo.toml for more details.

Build OpenSSL from source

Specify feature openssl-vendored to let openssl build from source.

bash cargo build --features "openssl-vendored"

Getting Started

Create a ShadowSocks' configuration file. Example

json { "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 explanation 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:

json { "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:

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

If you Build it with Cargo:

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

List all available arguments with -h.

Usage

Socks5 Local client

```bash

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" ```

HTTP Local client

```bash

Read local client configuration from file

sslocal -c /path/to/shadowsocks.json --protocol http ```

All parameters are the same as Socks5 client, except --protocol http.

Tunnel Local client

```bash

Read local client configuration from file

Set 127.0.0.1:8080 as the target for forwarding to

sstunnel -c /path/to/shadowsocks.json -f "127.0.0.1:8080" ```

sstunnel basically works the same as sslocal, only it doesn't have any client negociation process, just establishes a tunnel to the forward address.

Transparent Proxy Local client

NOTE: This is currently only supports

```bash

Read local client configuration from file

ssredir -c /path/to/shadowsocks.json ```

Redirects connections with iptables configurations to the port that ssredir is listening on.

Server

```bash

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" ```

Server Manager

Supported Manage Multiple Users API:

NOTE: stat command is not supported. Because servers are running in the same process with the manager itself.

```bash

Start it just with --manager-address command line parameter

ssmanager --manager-address "127.0.0.1:6100"

For *nix system, manager can bind to unix socket address

ssmanager --manager-address "/tmp/shadowsocks-manager.sock"

You can also provide a configuration file

#

manager_address key must be provided in the configuration file

ssmanager -c /path/to/shadowsocks.json

Create one server by UDP

echo 'add: {"server_port":8388,"password":"hello-kitty"}' | nc -u '127.0.0.1' '6100'

Close one server by unix socket

echo 'remove: {"server_port":8388}' | nc -Uu '/tmp/shadowsocks-manager.sock' ```

For manager UI, check more details in the shadowsocks-manager project.

Example configuration:

```jsonc { // Required option // Address that ssmanager is listening on "manageraddress": "127.0.0.1", "managerport": 6100,

// Or bind to a Unix Domain Socket
"manager_address": "/tmp/shadowsocks-manager.sock",

"servers": [
    // These servers will be started automatically when ssmanager is started
],

// Outbound socket binds to this IP address
// For choosing different network interface on the same machine
"local_address": "xxx.xxx.xxx.xxx",

// Other options that may be passed directly to new servers

} ```

Supported Ciphers

Stream Ciphers

AEAD Ciphers

ACL

sslocal, ssserver, ssredir and ssmanager support ACL file with syntax like shadowsocks-libev. Some examples could be found in here.

Available sections

Example

```ini

SERVERS

For ssserver, accepts requests from all clients by default

[accept_all]

Blocks these clients

[black_list] 1.2.3.4 127.0.0.1/8

Disallow these outbound addresses

[outboundblocklist] 127.0.0.1/8 ::1 (^|.)baidu.com

CLIENTS

For sslocal, ..., bypasses all targets by default

[bypass_all]

Proxy these addresses

[proxy_list] (^|.)google.com 8.8.8.8 ```

Useful Tools

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

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