Run client(enable http proxy)

./opensocks-linux-amd64 -s=YOUR_DOMIAN:8081 -l=127.0.0.1:1080 -k=123456 -p kcp -obfs -http-proxy -http 127.0.0.1:8000

Run server

./opensocks-linux-amd64 -S -k=123456 -obfs -p kcp

Docker

Run client

docker run -d --restart=always  --network=host \
--name opensocks-client netbyte/opensocks -s=YOUR_DOMIAN:8081 -l=127.0.0.1:1080 -k=123456 -p ws -obfs

Run server

docker run  -d --restart=always --net=host \
--name opensocks-server netbyte/opensocks -S -k=123456 -obfs
