wsproxy

This program enables port forwarding on top of WebSocket similiar to ssh local port forwarding.

Build

Make sure the WebSocket++ and boost libraries are pre-installed. Or you can install with the following commands on Ubuntu.

sudo apt install libwebsocketpp-dev libboost-all-dev

Then build with CMake.

mkdir build && cd build
cmake ..
make all

Server

Run wspserver on your server with listening port and forwarding port.

./wspserver 1234 4321  # listen on 1234 and forward to 4321

Client

Run wsplisten with server addr:port and the listening port.

./wspclient 8.8.8.8:1234 1080  # listen on 1080 and the server is listening on 8.8.8.8:1234

Now any TCP data to localhost:1080 will be forwarded to 8.8.8.8:4321

TODO

1. enable the client to assign the forwarding port.
2. enable encryption by using wss.
