RTCTunnel
RTCTunnel builds network tunnels over WebRTC.
WARNING:
This is a proof of concept and should NOT be used in production. Errors/Exceptions like disconnects and invalid data are not well handled, and may result in panics.
An overview of the application and how and why it was built is available here: RTCTunnel: Building a WebRTC Proxy with Go.
Installation
RTCTunnel can be installed via go install:
go install github.com/kami93/rtctunnel/cmd/rtctunnel@latest
Or downloaded from the releases page (for linux).
Usage
RTCTunnel creates a network tunnel over WebRTC between two peers. Those peers are identified by a public key.
To use RTCTunnel first create a config with:
rtctunnel init
You can see info with:
rtctunnel info
Once you've done that on both peers, copy the two public keys and add a route. A route has four components: a local peer, a local port, a remote peer and a remote port. All network connections and data sent to the local port will be forwarded to the remote peer. For example:
export CLIENT_KEY=
export SERVER_KEY=
rtctunnel add-route \
--local-peer=$CLIENT_KEY \
--local-port=6379 \
--remote-peer=$SERVER_KEY \
--remote-port=6379
The route must be added on both peers and the CLIENT_KEY and SERVER_KEY should be set to the peer keys.
Once the routes are added you can run rtctunnel with:
rtctunnel run
Typically it would be run in the background.
A docker-compose example is available in examples/redis.
Configuration
Configuration is stored in a yaml file based on github.com/kirsle/configdir:
Linux: $XDG_CONFIG_HOME or "$HOME/.config"
Windows: %APPDATA% or "C:\\Users\\%USER%\\AppData\\Roaming"
macOS: $HOME/Library/Application Support
You can see the path by running rtctunnel help.
Signal Channel
In addition to the key pair and routes you can set the signal channel in the config:
keypair:
public: xxx
private: xxx
routes: []
signalchannel: operator://localhost:8000
The default signal channel is apprtc:// which uses a websocket server for appr.tc.
