stund

A minimal asynchronous STUN server implementation.

The server implements the minimal necessary functionality from RFC 8489, namely the Binding Request.

The server is both IPv6 and IPv4 capable. When listening on IPv6 address, the server is capable of handling IPv6/IPv4 clients.

Running

To try out the server, just run:

$ cargo run

Testing

To verify the server functions properly, the following tools may be used:

• Trickle ICE tester from WebRTC github samples
• IceTest.Info
• stunclient package from stunprotocol.org. Note: the server will report an error due to stunclient sending additional attributes not recognized by this implementation
