shadowsocks

This is a port of shadowsocks.

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

Library	Description
shadowsocks	shadowsocks core protocol
shadowsocks-service	Services for serving shadowsocks
shadowsocks-rust	Binaries running common shadowsocks services

Build & Install

Optional Features

trust-dns - Uses trust-dns-resolver as DNS resolver instead of tokio's builtin.
local-http - Allow using HTTP protocol for sslocal
- local-http-native-tls - Support HTTPS with native-tls
- local-http-rustls - Support HTTPS with rustls
local-tunnel - Allow using tunnel protocol for sslocal
local-socks4 - Allow using SOCKS4/4a protocol for sslocal
local-redir - Allow using redir (transparent proxy) protocol for sslocal
local-dns - Allow using dns protocol for sslocal, serves as a DNS server proxying queries to local or remote DNS servers by ACL rules
stream-cipher - Enable deprecated stream ciphers. WARN: stream ciphers are UNSAFE!
aead-cipher-extra - Enable non-standard AEAD ciphers

Memory Allocators

This project uses system (libc) memory allocator (Rust's default). But it also allows you to use other famous allocators by features:

jemalloc - Uses jemalloc as global memory allocator
mimalloc - Uses mi-malloc as global memory allocator
tcmalloc - Uses TCMalloc as global memory allocator. It tries to link system-wide tcmalloc by default, use vendored from source with tcmalloc-vendored.
snmalloc - Uses snmalloc as global memory allocator
rpmalloc - Uses rpmalloc as global memory allocator

crates.io

Install from crates.io:

# Set default toolchain to nightly
rustup default nightly
# RECOMMEND: Check the rust-toolchain file in the project root and use the recomended nightly version
# For example:
# rustup default nightly-2021-06-03

# Install from crates.io
cargo install shadowsocks-rust

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

Download release

Download static-linked build here.

build-windows: Build for x86_64-pc-windows-msvc
build-linux: Build for x86_64-unknown-linux-gnu, Debian 9 (Stretch), GLIBC 2.18
build-docker: Build for x86_64-unknown-linux-musl, x86_64-pc-windows-gnu, ... (statically linked)

Build from source

Use cargo to build. NOTE: RAM >= 2GiB

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, ssmanager and ssurl will be installed to /usr/local/bin (variable PREFIX).

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

target-cpu optimization

If you are building for your current CPU platform (for example, build and run on your personal computer), it is recommended to set target-cpu=native feature to let rustc generate and optimize code for the CPU running the compiler.

export RUSTFLAGS="-C target-cpu=native"

Build standalone binaries

Requirements:

Docker

./build/build-release

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

./build/shadowsocks-${VERSION}-stable.x86_64-unknown-linux-musl.tar.xz
./build/shadowsocks-${VERSION}-stable.x86_64-pc-windows-gnu.zip

Read Cargo.toml for more details.

Getting Started

Create a ShadowSocks' configuration file. Example

{
    "server": "my_server_ip",
    "server_port": 8388,
    "password": "mypassword",
    "method": "aes-256-gcm",
    // ONLY FOR `sslocal`
    // Delete these lines if you are running `ssserver` or `ssmanager`
    "local_address": "127.0.0.1",
    "local_port": 1080
}

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 server. You can also disable individual servers.

{
    "servers": [
        {
            "address": "127.0.0.1",
            "port": 8388,
            "password": "hello-world",
            "method": "aes-256-gcm",
            "timeout": 7200
        },
        {
            "address": "127.0.0.1",
            "port": 8389,
            "password": "hello-kitty",
            "method": "chacha20-ietf-poly1305"
        },
        {
            "disabled": true,
            "address": "eg.disable.me",
            "port": 8390,
            "password": "hello-internet",
            "method": "chacha20-ietf-poly1305"
        }
    ],
    // ONLY FOR `sslocal`
    // Delete these lines if you are running `ssserver` or `ssmanager`
    "local_port": 1080,
    "local_address": "127.0.0.1"
}

sslocal automatically selects the best server with the lowest latency and the highest availability.

Start Shadowsocks client and server with:

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

Start local client with configuration file

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

Socks5 Local client

# Pass all parameters via command line
sslocal -b "127.0.0.1:1080" -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty" --plugin "v2ray-plugin" --plugin-opts "server;tls;host=github.com"

# Pass server with SIP002 URL
sslocal -b "127.0.0.1:1080" --server-url "ss://YWVzLTI1Ni1nY206cGFzc3dvcmQ@127.0.0.1:8388/?plugin=v2ray-plugin%3Bserver%3Btls%3Bhost%3Dgithub.com"

HTTP Local client

sslocal -b "127.0.0.1:3128" --protocol http -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty"

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

Tunnel Local client

# Set 127.0.0.1:8080 as the target for forwarding to
sslocal --protocol tunnel -b "127.0.0.1:3128" -f "127.0.0.1:8080" -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty"

--protocol tunnel enables local client Tunnel mode
-f "127.0.0.1:8080 sets the tunnel target address

Transparent Proxy Local client

NOTE: It currently only supports

Linux (with iptables targets REDIRECT and TPROXY)
BSDs (with pf), such as OS X 10.10+, FreeBSD, ...

sslocal -b "127.0.0.1:60080" --protocol redir -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty" --tcp-redir "redirect" --udp-redir "tproxy"

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

--protocol redir enables local client Redir mode
(optional) --tcp-redir sets TCP mode to REDIRECT (Linux)
(optional) --udp-redir sets UDP mode to TPROXY (Linux)

Tun interface client

NOTE: It currently only supports

Linux, Android
macOS, iOS

Linux

Create a Tun interface with name tun0

ip tuntap add mode tun tun0
ifconfig tun0 inet 10.255.0.1 netmask 255.255.255.0 up

Start sslocal with --protocol tun and binds to tun0

sslocal --protocol tun -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty" --outbound-bind-interface lo0 --tun-interface-name tun0

macOS

sslocal --protocol tun -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty" --outbound-bind-interface lo0 --tun-interface-address 10.255.0.1/24

It will create a Tun interface with address 10.255.0.1 and netmask 255.255.255.0.

(OPTIONAL) macOS requires adding a route entry to redirect packets that destinated to 10.155.0.1 (the address of the Tun interface) to the Tun interface itself.

# 10.255.0.1 address
# 255.255.255.0 netmask
# utun8 tun's interface name
route add -net 10.255.0.1 -netmask 255.255.255.0 -interface utun8

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 "v2ray-plugin" --plugin-opts "server;tls;host=github.com"

Server Manager

Supported Manage Multiple Users API:

add - Starts a server instance
remove - Deletes an existing server instance
list - Lists all current running servers
ping - Lists all servers' statistic data

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

# 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:

{
    // Required option
    // Address that ssmanager is listening on
    "manager_address": "127.0.0.1",
    "manager_port": 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
    ],

ACL

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

Available sections

For local servers (sslocal, ssredir, ...)
- Modes:
  - [bypass_all] - ACL runs in BlackList mode. Bypasses all addresses that didn't match any rules.
  - [proxy_all] - ACL runs in WhiteList mode. Proxies all addresses that didn't match any rules.
- Rules:
  - [bypass_list] - Rules for connecting directly
  - [proxy_list] - Rules for connecting through proxies
For remote servers (ssserver)
- Modes:
  - [reject_all] - ACL runs in BlackList mode. Rejects all clients that didn't match any rules.
  - [accept_all] - ACL runs in WhiteList mode. Accepts all clients that didn't match any rules.
- Rules:
  - [white_list] - Rules for accepted clients
  - [black_list] - Rules for rejected clients
  - [outbound_block_list] - Rules for blocking outbound addresses.

Example

# 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
[outbound_block_list]
127.0.0.1/8
::1
# Using regular expression
^[a-z]{5}\.baidu\.com
# Match exactly
|baidu.com
# Match with subdomains
||google.com
# An internationalized domain name should be converted to punycode
# |☃-⌘.com - WRONG
|xn----dqo34k.com
# ||джpумлатест.bрфa - WRONG
||xn--p-8sbkgc5ag7bhce.xn--ba-lmcq

# CLIENTS
# For sslocal, ..., bypasses all targets by default
[bypass_all]

# Proxy these addresses
[proxy_list]
||google.com
8.8.8.8

Useful Tools

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:

TODO

Documentation

Support more ciphers without depending on libcrypto (waiting for an acceptable Rust crypto lib implementation)
Windows support.
Build with stable rustc (blocking by crypto2).
Support HTTP Proxy protocol
AEAD ciphers. (proposed in SIP004, still under discussion)
Choose server based on delay #152
