Violet - Lightweight STUN/TURN server

Violet is a lightweight STUN/TURN server (RFC8489 and RFC8656) written in C without dependencies, based on libjuice.

Violet is licensed under GPLv2 or later, see LICENSE.

"Mercy! Save us!" yelled Mrs Beauregarde. "[...] Violet, you’re turning violet, Violet!" [...]

"Squeeze her," said Mr Wonka. "We've got to squeeze the juice out of her immediately."

-- Charlie and the Chocolate Factory, Roald Dahl

Dependencies

Attribute EVEN-PORT

Implement the EVEN-PORT attribute as it is needed by older agents for RTCP.

For reference: https://tools.ietf.org/html/rfc8656#section-18.7

License

Any chance of you licensing violet as LGPL? (like libdatachannel)

Connecting each other via STUN server works only in local network.

Stun server doesn't gather candidates

Hey, turn server works perfectly, but stun server doesn't work properly it doesn't gather candidates.

Segmentation fault during TURN allocate request

Hello,

I wanted to report a segmentation fault during a TURN allocate request.
The bugs happens 4 times in a row. (out of 4 try, so every time).
It happens when the connection is closing or when I start a second one.

I'm creating the webrtc peer with libdatachannel and libjuice on one side:

IceServer turn("160.98.47.137", 8000, "user", "password", IceServer::RelayType::TurnUdp);
config.iceServers.emplace_back("stun:stun.1.google.com:19302");
config.iceServers.emplace_back(turn);

And on the web browser side:

if (document.getElementById('use-stun').checked) {
    config.iceServers = [
    {
        urls: ['stun:stun.l.google.com:19302']
    },
    {
        urls: ['turn:160.98.47.137:8000'],
        username: 'user',
        credential: 'password'
    }
    ];
}

let pc = new RTCPeerConnection(config);

Here is the log:

And here is the configuration file that I used:

# Port range for TURN relay

# TURN credentials with optional quota (default none)

Thank you for your work by the way.

Docker image

This project is super awesome. I would like to offer it as a coturn alternative for people that like to install my Open Source tool https://github.com/holtwick/briefing/

Did you consider bundling it for Docker via https://hub.docker.com ? I think this would make it very attractive for regular users.
