shadowsocks lightweight implementation(server side)

a proxy tool written in rust.

build

git clone https://github.com/kirito41dd/ss-light.git
cd ss-light && cargo test
cargo build --release
./target/release/server --version

usage

run with config.toml:

./server -c config.toml

passwd = "123456"
method = "aes-256-gcm"
bind_addr = "0.0.0.0"
bind_port = 6789
timeout = 2000         # ms, timeout for tcp proxy handshake and tcp connect
log_level = "info"     # error warn info debug trace
console_log = true
# file_log_dir = "applog/" # if no set, don't log to file
udp_capacity = 1000  # udp relay worker pool size, one proxy req one worker
udp_expiry_time = 30 # sec, expiration time for udp relay worker keep alive
# [plugin]
# name = "v2ray-plugin"
# opts = "server"
# args = []

or override config with:

./server -c config.toml -l 127.0.0.1 -p 1080 -k <a-secure-password>

if without -c, default config file is $pwd/config.toml

more usage:

./server -h

quick start with docker

tips: use <ctrl-p><ctrl-q> exit container but keep it running

v2ray-plugin are recommended

start with default config but specify password:

docker run --rm -it -p 8888:6789/tcp -p 8888:6789/udp kirito41dd/ss-light -k passwd123

or start with custom config file:

1. create new config dir in home then add config.toml file:

   mkdir $HOME/.ss-light && cd $HOME/.ss-light
   touch config.toml
   

2. edit config.toml like here
3. run docker:

   docker run --rm -it -v $HOME/.ss-light:/app -p 8888:6789/tcp -p 8888:6789/udp kirito41dd/ss-light

use v2ray-plugin: (websocket)

docker run --rm -it -p 8888:6789/tcp -p 8888:6789/udp kirito41dd/ss-light -k passwd123 --plugin v2ray-plugin --plugin-opts server

use other SIP003 plugins:

1. like start with custom config file, download plugin to $HOME/.ss-light
2. start

   docker run --rm -it -v $HOME/.ss-light:/app -p 8888:6789/tcp -p 8888:6789/udp kirito41dd/ss-light --plugin=/app/<your-plugin>
   

best practice

ss-light + v2ray-plugin + cloudflare DNS

1. apt -y install python3-certbot-nginx nginx
2. vim /etc/nginx/conf.d/ss.conf

   server {
       listen      80;
       server_name xxx.com;
   
       location /dog {
           proxy_pass              http://127.0.0.1:8888;
           proxy_redirect          off;
           proxy_http_version      1.1;
           proxy_set_header        Upgrade $http_upgrade;
           proxy_set_header        Connection "upgrade";
           proxy_set_header        Host $http_host;
       }
   }
   

3. certbot --nginx --agree-tos --no-eff-email --email [email protected]
4. systemctl restart nginx
5. docker run --restart=always -it -p 127.0.0.1:8888:6789/tcp kirito41dd/ss-light -k passwd123 --plugin v2ray-plugin --plugin-opts "server;path=/dog;loglevel=none"
6. setting your cloudflare SSL/TLS option Full or Full (strict)
7. use client: xxx.com 443 passwd123 aes-256-gcm v2ray-plugin websocket xxx.com tsl /dog
