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:

  1. # Install from crates.io
  2. 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:

  1. brew install shadowsocks-rust

Install using snap

  1. # Install from snapstore
  2. snap install shadowsocks-rust
  4. # List services
  5. snap services shadowsocks-rust
  7. # Enable and start shadowsocks-rust.sslocal-daemon snap service
  8. snap start --enable shadowsocks-rust.sslocal-daemon
  10. # Show generated systemd service status
  11. systemctl status snap.shadowsocks-rust.sslocal-daemon.service
  13. # Override generated systemd service (configure startup options)

Docker

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

:warning: 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.

  1. docker pull ghcr.io/shadowsocks/sslocal-rust:latest
  2. 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.

  1. docker buildx build -t shadowsocks/ssserver-rust:latest -t shadowsocks/ssserver-rust:v1.15.2 --target ssserver .
  2. 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.

  1. docker run --name sslocal-rust \
  2.   --restart always \
  3.   -p 1080:1080/tcp \
  4.   -v /path/to/config.json:/etc/shadowsocks-rust/config.json \
  5.   -dit ghcr.io/shadowsocks/sslocal-rust:latest
  7. docker run --name ssserver-rust \
  8.   --restart always \
  9.   -p 8388:8388/tcp \
  10.   -p 8388:8388/udp \
  11.   -v /path/to/config.json:/etc/shadowsocks-rust/config.json \
  12.   -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:

  1. # This is the shadowsocks config which will be mount to /etc/shadowocks-rust.
  2. # You can put arbitrary yaml here, and it will be translated to json before mounting.
  3. servers:
  4. - server: "::"
  5.   server_port: 8388
  6.   service_port: 80 # the k8s service port, default to server_port
  7.   password: mypassword
  8.   method: aes-256-gcm
  9.   fast_open: true
  10.   mode: tcp_and_udp
  11.   # plugin: v2ray-plugin
  12.   # plugin_opts: server;tls;host=github.com
  14. # Whether to download v2ray and xray plugin.
  15. downloadPlugins: false
  17. # Name of the ConfigMap with config.json configuration for shadowsocks-rust.
  18. configMapName: ""
  20. service:
  21.   # Change to LoadBalancer if you are behind a cloud provider like aws, gce, or tke.
  22.   type: ClusterIP
  24. # Bind shadowsocks port port to host, i.e., we can use host:port to access shawdowsocks server.
  25. hostPort: false
  27. replicaCount: 1
  29. image:
  30.   repository: ghcr.io/shadowsocks/ssserver-rust
  31.   pullPolicy: IfNotPresent
  32.   # Overrides the image tag whose default is the chart appVersion.
  33.   tag: "latest"

Build from source

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

  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.

  1. 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.

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

Build standalone binaries

Requirements:

  • Docker
  1. ./build/build-release

Then sslocal, ssserver, ssmanager, ssservice 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.

For Linux with low GLIBC versions, set CROSS_CONFIG to CentOS based image:

  1. export CROSS_CONFIG=Cross-centos.toml

Getting Started

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

  1. ssservice genkey -m "aes-128-gcm"

Create a ShadowSocks’ configuration file. Example

  1. {
  2.     "server": "my_server_ip",
  3.     "server_port": 8388,
  4.     "password": "rwQc8qPXVsRpGx3uW+Y3Lj4Y42yF9Bs0xg1pmx8/+bo=",
  5.     "method": "aes-256-gcm",
  6.     // ONLY FOR `sslocal`
  7.     // Delete these lines if you are running `ssserver` or `ssmanager`
  8.     "local_address": "127.0.0.1",
  9.     "local_port": 1080
  10. }

Detailed explanation of the configuration file could be found in shadowsocks’ documentation. (Link to original project, not maintained anymore !)

:warning: For snap installations, configuration file is most probably located in /var/snap/shadowsocks-rust/common/etc/shadowsocks-rust/config.json (see https://github.com/shadowsocks/shadowsocks-rust/issues/621 / https://github.com/shadowsocks/shadowsocks-rust/issues/1146)

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.

  1. {
  2.     "servers": [
  3.         {
  4.             "server": "127.0.0.1",
  5.             "server_port": 8388,
  6.             "password": "rwQc8qPXVsRpGx3uW+Y3Lj4Y42yF9Bs0xg1pmx8/+bo=",
  7.             "method": "aes-256-gcm",
  8.             "timeout": 7200
  9.         },
  10.         {
  11.             "server": "127.0.0.1",
  12.             "server_port": 8389,
  13.             "password": "/dliNXn5V4jg6vBW4MnC1I8Jljg9x7vSihmk6UZpRBM=",
  14.             "method": "chacha20-ietf-poly1305"
  15.         },
  16.         {
  17.             "disabled": true,
  18.             "server": "eg.disable.me",
  19.             "server_port": 8390,
  20.             "password": "mGvbWWay8ueP9IHnV5F1uWGN2BRToiVCAWJmWOTLU24=",
  21.             "method": "chacha20-ietf-poly1305"
  22.         }
  23.     ],
  24.     // ONLY FOR `sslocal`
  25.     // Delete these lines if you are running `ssserver` or `ssmanager`
  26.     "local_port": 1080,
  27.     "local_address": "127.0.0.1"
  28. }

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

Start Shadowsocks client and server with:

  1. sslocal -c config.json
  2. ssserver -c config.json

If you Build it with Cargo:

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

List all available arguments with -h.

Usage

Start local client with configuration file

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

Socks5 Local client

  1. # Pass all parameters via command line
  2. 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"
  4. # Pass server with SIP002 URL
  5. 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

  1. 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

  1. # Set 127.0.0.1:8080 as the target for forwarding to
  2. 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, …
  1. 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
  • Windows

Linux

Create a Tun interface with name tun0

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

Start sslocal with --protocol tun and binds to tun0

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

macOS

  1. 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.

Windows

Download wintun.dll from Wintun, and place it in the folder with shadowsocks’ runnable binaries, or in the system PATH.

  1. sslocal --protocol tun -s "[::1]:8388" -m "aes-256-gcm" -k "hello-kitty" --outbound-bind-interface "Ethernet 0" --tun-interface-name "shadowsocks"

Local client for Windows Service

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

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

Install it as a Windows Service (PowerShell):

  1. New-Service -Name "shadowsocks-local-service" `
  2.             -DisplayName "Shadowsocks Local Service" `
  3.             -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

  1. # Read server configuration from file
  2. ssserver -c /path/to/shadowsocks.json
  4. # Pass all parameters via command line
  5. 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.

  1. # Start it just with --manager-address command line parameter
  2. ssmanager --manager-address "127.0.0.1:6100"
  4. # For *nix system, manager can bind to unix socket address
  5. ssmanager --manager-address "/tmp/shadowsocks-manager.sock"
  7. # You can also provide a configuration file
  8. #
  9. # `manager_address` key must be provided in the configuration file
  10. ssmanager -c /path/to/shadowsocks.json
  12. # Create one server by UDP
  13. echo 'add: {"server_port":8388,"password":"hello-kitty"}' | nc -u '127.0.0.1' '6100'
  15. # Close one server by unix socket
  16. echo 'remove: {"server_port":8388}' | nc -Uu '/tmp/shadowsocks-manager.sock'

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

Example configuration:

  1. {
  2.     // Required option
  3.     // Address that ssmanager is listening on
  4.     "manager_address": "127.0.0.1",
  5.     "manager_port": 6100,
  7.     // Or bind to a Unix Domain Socket
  8.     "manager_address": "/tmp/shadowsocks-manager.sock",
  10.     "servers": [
  11.         // These servers will be started automatically when ssmanager is started
  12.     ],
  14.     // Outbound socket binds to this IP address
  15.     // For choosing different network interface on the same machine
  16.     "local_address": "xxx.xxx.xxx.xxx",
  18.     // Other options that may be passed directly to new servers
  19. }

Configuration

  1. {

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.

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 WhiteList mode. Bypasses all addresses except those matched any rules.
      • [proxy_all] - ACL runs in BlackList mode. Proxies all addresses except those matched any rules. (default)
    • Rules:
      • [bypass_list] - Rules for connecting directly
      • [proxy_list] - Rules for connecting through proxies
  • For remote servers (ssserver)
    • Modes:
      • [reject_all] - ACL runs in WhiteList mode. Rejects all clients except those matched any rules.
      • [accept_all] - ACL runs in BlackList mode. Accepts all clients except those matched any rules. (default)
      • [outbound_block_all] - Outbound ACL runs in WhiteList mode. Blockes all outbound addresses except those matched any rules.
      • [outbound_allow_all] - Outbound ACL runs in BlackList mode. Allows all outbound addresses except those matched any rules. (default)
    • Rules:
      • [white_list] - Rules for accepted clients
      • [black_list] - Rules for rejected clients
      • [outbound_block_list] - Rules for blocking outbound addresses.
      • [outbound_allow_list] - Rules for allowing outbound addresses.

  2. # For ssserver, accepts requests from all clients by default
  3. [accept_all]
  5. # Blocks these clients
  6. [black_list]
  7. 1.2.3.4
  8. 127.0.0.1/8
  10. # Disallow these outbound addresses
  11. [outbound_block_list]
  12. 127.0.0.1/8
  13. ::1
  14. # Using regular expression
  15. ^[a-z]{5}\.baidu\.com
  16. # Match exactly
  17. |baidu.com
  18. # Match with subdomains
  19. ||google.com
  20. # An internationalized domain name should be converted to punycode
  21. # |☃-⌘.com - WRONG
  22. |xn----dqo34k.com
  23. # ||джpумлатест.bрфa - WRONG
  24. ||xn--p-8sbkgc5ag7bhce.xn--ba-lmcq
  26. # CLIENTS
  27. # For sslocal, ..., bypasses all targets by default
  28. [bypass_all]
  30. # Proxy these addresses
  31. [proxy_list]
  32. ||google.com
  33. 8.8.8.8

Useful Tools

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

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