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:

# Install from crates.io
cargo install shadowsocks-rust

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

Install using Homebrew

For macOS and Linux, you can install it using Homebrew:

brew install shadowsocks-rust

Install using snap

# Install from snapstore
snap install shadowsocks-rust

# List services
snap services shadowsocks-rust

# Enable and start shadowsocks-rust.sslocal-daemon snap service

Docker

This project provided Docker images for the linux/i386 and linux/amd64 and linux/arm64/v8 architectures.

⚠️ Docker containers do not have access to IPv6 by default: Make sure to disable IPv6 Route in the client or enable IPv6 access to docker containers.

Pull from GitHub Container Registry

Docker will pull the image of the appropriate architecture from our GitHub Packages.

docker pull ghcr.io/shadowsocks/sslocal-rust:latest
docker pull ghcr.io/shadowsocks/ssserver-rust:latest

Build on the local machine（Optional）

If you want to build the Docker image yourself, you need to use the BuildX.

docker buildx build -t shadowsocks/ssserver-rust:latest -t shadowsocks/ssserver-rust:v1.15.2 --target ssserver .
docker buildx build -t shadowsocks/sslocal-rust:latest -t shadowsocks/sslocal-rust:v1.15.2 --target sslocal .

Run the container

You need to mount the configuration file into the container and create an external port map for the container to connect to it.

docker run --name sslocal-rust \
  --restart always \
  -p 1080:1080/tcp \
  -v /path/to/config.json:/etc/shadowsocks-rust/config.json \
  -dit ghcr.io/shadowsocks/sslocal-rust:latest

docker run --name ssserver-rust \
  --restart always \
  -p 8388:8388/tcp \
  -p 8388:8388/udp \
  -v /path/to/config.json:/etc/shadowsocks-rust/config.json \
  -dit ghcr.io/shadowsocks/ssserver-rust:latest

Deploy to Kubernetes

This project provided yaml manifests for deploying to Kubernetes.

You can leverage k8s Service to expose traffic outside, like LoadBalancer or NodePort which gains more fine-grained compared with fixed host or port.

For a more interesting use case, you can use a Ingress(Istio, nginx, etc.) which routes the matched traffic to shadowsocks along with the real web service.

Using `kubectl`

kubectl apply -f https://github.com/shadowsocks/shadowsocks-rust/raw/master/k8s/shadowsocks-rust.yaml

You can change the config via editing the ConfigMap named shadowsocks-rust.

For more fine-grained control, use helm.

Using `helm`

helm install my-release k8s/chart -f my-values.yaml

Below is the common default values you can change:

# This is the shadowsocks config which will be mount to /etc/shadowocks-rust.
# You can put arbitrary yaml here, and it will be translated to json before mounting.
servers:
- server: "::"
  server_port: 8388
  service_port: 80 # the k8s service port, default to server_port
  password: mypassword
  method: aes-256-gcm
  fast_open: true
  mode: tcp_and_udp
  # plugin: v2ray-plugin
  # plugin_opts: server;tls;host=github.com

# Whether to download v2ray and xray plugin.
downloadPlugins: false

# Name of the ConfigMap with config.json configuration for shadowsocks-rust.
configMapName: ""

service:
  # Change to LoadBalancer if you are behind a cloud provider like aws, gce, or tke.
  type: ClusterIP

# Bind shadowsocks port port to host, i.e., we can use host:port to access shawdowsocks server.
hostPort: false

replicaCount: 1

image:
  repository: ghcr.io/shadowsocks/ssserver-rust
  pullPolicy: IfNotPresent
  # Overrides the image tag whose default is the chart appVersion.
  tag: "latest"

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

Generate a safe and secured password for a specific encryption method (aes-128-gcm in the example) with:

ssservice genkey -m "aes-128-gcm"

Create a ShadowSocks' configuration file. Example

{
    "server": "my_server_ip",
    "server_port": 8388,
    "password": "rwQc8qPXVsRpGx3uW+Y3Lj4Y42yF9Bs0xg1pmx8/+bo=",
    "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": [
        {
            "server": "127.0.0.1",
            "server_port": 8388,
            "password": "rwQc8qPXVsRpGx3uW+Y3Lj4Y42yF9Bs0xg1pmx8/+bo=",
            "method": "aes-256-gcm",
            "timeout": 7200
        },
        {
            "server": "127.0.0.1",
            "server_port": 8389,
            "password": "/dliNXn5V4jg6vBW4MnC1I8Jljg9x7vSihmk6UZpRBM=",
            "method": "chacha20-ietf-poly1305"
        },
        {
            "disabled": true,
            "server": "eg.disable.me",
            "server_port": 8390,
            "password": "mGvbWWay8ueP9IHnV5F1uWGN2BRToiVCAWJmWOTLU24=",
            "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://[email protected]: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.

Local client for Windows Service

Compile it by enabling --features "winservice" (not included in the default build):

cargo build --release --bin "sswinservice" --features "winservice"

Install it as a Windows Service (PowerShell):

New-Service -Name "shadowsocks-local-service" `
            -DisplayName "Shadowsocks Local Service" `
            -BinaryPathName "<Path\to>\sswinservice.exe local -c <Path\to>\local_config.json"

There are other ways to install sswinservice as a Windows Service, for example, the sc command.

As you may have noticed that the -BinaryPathName contains not only just the sswinservice.exe, but local -c local_config.json. These command line parameters will be used as the default parameter when the Windows Service starts. You can also start the service with customized parameters.

Learn more from Microsoft's Document.

The sswinservice's parameter works exactly the same as ssservice. It supports local, server and manager subcommands.

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
    ],

    // 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
}

Configuration

SOCKS5 Authentication Configuration

The configuration file is set by socks5_auth_config_path in locals.

{
    // Password/Username Authentication (RFC1929)
    "password": {
        "users": [
            {
                "user_name": "USERNAME in UTF-8",
                "password": "PASSWORD in UTF-8"
            }
        ]
    }
}

Environment Variables

SS_SERVER_PASSWORD: A default password for servers that created from command line argument (--server-addr)
SS_SYSTEM_DNS_RESOLVER_FORCE_BUILTIN: "system" DNS resolver force use system's builtin (getaddrinfo in *NIX)

Supported Ciphers

AEAD 2022 Ciphers

2022-blake3-aes-128-gcm, 2022-blake3-aes-256-gcm
2022-blake3-chacha20-poly1305, 2022-blake3-chacha8-poly1305

These Ciphers require "password" to be a Base64 string of key that have exactly the same length of Cipher's Key Size. It is recommended to use ssservice genkey -m "METHOD_NAME" to generate a secured and safe key.

AEAD Ciphers

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://[email protected]:8388/?plugin=obfs-local%3Bobfs%3Dhttp%3Bobfs-host%3Dwww.baidu.com

Notes

It supports the following features:

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.
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
