shadowsocks-rust
This is a port of shadowsocks.
shadowsocks is a fast tunnel proxy that helps you bypass firewalls.
Dependencies
- libcrypto (OpenSSL) (Required for
aes-*
,camellia-*
andrc4
ciphers) - libsodium >= 1.0.7 (Required for ciphers that are provided by libsodium)
Build & Install
Optional Features
-
sodium
- Enabled linking tolibsodium
, which will also enable ciphers that depending onlibsodium
. -
rc4
- Enabledrc4
encryption algorithm. Some OpenSSL Crypto does not ship withrc4
, because it was already deprecated in 2015. -
aes-cfb
- Enabledaes-*-cfb
encryption algorithm. -
aes-ctr
- Enabledaes-*-ctr
encryption algorithm. -
camellia-cfb
- Enabledcamellia-*-cfb
encryption algorithm. -
single-threaded
- Letsslocal
andssserver
run in single threaded mode (by using Tokio'sbasic_scheduler
). -
trust-dns
- Usestrust-dns-resolver
as DNS resolver instead oftokio
's builtin.
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:
then you can find sslocal
and ssserver
in $CARGO_HOME/bin
.
Download release
Requirements:
- Linux x86_64
- Windows x86_64
Download static-linked build here.
Build from source
Use cargo to build.
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
Then sslocal
and ssserver
will appear in ./target/(debug|release)/
, it works similarly as the two binaries in the official ShadowSocks' implementation.
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
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
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:
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:
If you Build it with Cargo:
List all available arguments with -h
.
Usage
Socks5 Local client
# Read local client configuration from file
# Pass all parameters via command line
# Pass server with SIP002 URL
HTTP Local client
# Read local client configuration from file
All parameters are the same as Socks5 client, except --protocol http
.
Tunnel Local client
# Read local client configuration from file
# Set 127.0.0.1:8080 as the target for forwarding to
sstunnel
basically works the same as sslocal
, only it doesn't have any client negociation process, just establishes a tunnel to the forward
address.
Server
# Read server configuration from file
# Pass all parameters via command line

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:
- Socks5 CONNECT command
- Socks5 UDP ASSOCIATE command (partial)
- Various crypto algorithms
- Load balancing (multiple servers) and server delay checking
- SIP004 AEAD ciphers
- SIP003 Plugins
- SIP002 Extension ss URLs
- HTTP Proxy Supports (RFC 7230 and CONNECT)
- Defend against replay attacks, shadowsocks/shadowsocks-org#44
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
. - Support HTTP Proxy protocol
- One-time Auth. (Already deprecated according to Shadowsocks' community)
- AEAD ciphers. (proposed in SIP004, still under discussion)
- Choose server based on delay #152
- Support TCP Fast Open
