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

-
trust-dns
- Usestrust-dns-resolver
as DNS resolver instead oftokio
's builtin. -
local-http
- Allow using HTTP protocol forsslocal
-
local-http-native-tls
- Support HTTPS withnative-tls
-
local-http-rustls
- Support HTTPS withrustls
-
-
local-tunnel
- Allow using tunnel protocol forsslocal
-
local-socks4
- Allow using SOCKS4/4a protocol forsslocal
-
local-redir
- Allow using redir (transparent proxy) protocol forsslocal
-
local-dns
- Allow using dns protocol forsslocal
, 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
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 allocatormimalloc
- Uses mi-malloc as global memory allocatortcmalloc
- Uses TCMalloc as global memory allocator. It tries to link system-wide tcmalloc by default, use vendored from source withtcmalloc-vendored
.snmalloc
- Uses snmalloc as gloal memory allocatorrpmalloc
- Uses rpmalloc as global memory allocator
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
.

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.
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"
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.
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
.
Start local client with configuration file
# 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 "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"
# Read local client configuration from file
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
.
# Read local client configuration from file
# 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
NOTE: It currently only supports
- Linux (with
iptables
targetsREDIRECT
andTPROXY
) - BSDs (with
pf
), such as OS X 10.10+, FreeBSD, ...
# Read local client configuration from file
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 toREDIRECT
(Linux) - (optional)
--udp-redir
sets UDP mode toTPROXY
(Linux)
# 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"
Supported Manage Multiple Users API:
add
- Starts a server instanceremove
- Deletes an existing server instancelist
- Lists all current running serversping
- 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'

sslocal
, ssserver
, and ssmanager
support ACL file with syntax like shadowsocks-libev. Some examples could be found in here.
- For local servers (
sslocal
,ssredir
, ...)- Modes:
[bypass_all]
- ACL runs inBlackList
mode. Bypasses all addresses that didn't match any rules.[proxy_all]
- ACL runs inWhiteList
mode. Proxies all addresses that didn't match any rules.
- Rules:
[bypass_list]
- Rules for connecting directly[proxy_list]
- Rules for connecting through proxies
- Modes:
- For remote servers (
ssserver
)- Modes:

mode. Rejects all clients that didn't match any rules.[accept_all]
- ACL runs inWhiteList
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.
- Modes:
# SERVERS
# For ssserver, accepts requests from all clients by default

- Manager APIs, supporting Manage Multiple Users
- ACL (Access Control List)
- Support HTTP/HTTPS Proxy protocol
- 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 bycrypto2
). - Support HTTP Proxy protocol
- AEAD ciphers. (proposed in SIP004, still under discussion)
- Choose server based on delay #152
