A bash script for easy installation and configuration of a COTURN server. This script helps you set up a STUN/TURN server with basic authentication and no SSL.

This STUN/TURN server can be used in various WebRTC applications and VoIP solutions:

• Video conferencing applications
• Peer-to-peer file sharing
• Live streaming solutions
• Browser-based chat applications
• Online gaming platforms
• Remote desktop applications

• SIP clients (JsSIP, SIP.js)
• WebRTC-based softphones
• VoIP mobile applications
• IP PBX systems
• Video calling applications

Can be integrated with:

• JsSIP
• SIP.js
• WebRTC.js
• Janus Gateway
• FreeSWITCH
• Asterisk
• Kamailio
• OpenSIPS

let socket = new JsSIP.WebSocketInterface('wss://your-websocket-server');
let configuration = {
  sockets  : [ socket ],
  uri      : 'sip:your_extension@your-sip-domain',
  password : 'your-password',
  iceServers: [
    { urls: ['stun:your-ip:3478'] },
    {
      urls: ['turn:your-ip:3478'],
      username: 'your-turn-username',
      credential: 'your-turn-password'
    },
    {
      urls: ['stun:your-ip:3478'],
      username: 'your-turn-username',
      credential: 'your-turn-password'
    }
  ]
};

let phone = new JsSIP.UA(configuration);
phone.start();

const configuration = {
  iceServers: [
    {
      urls: "stun:your-ip:3478"
    },
    {
      urls: "turn:your-ip:3478",
      username: "your-turn-username",
      credential: "your-turn-password"
    },
    {
      urls: ['stun:your-ip:3478'],
      username: 'your-turn-username',
      credential: 'your-turn-password'
    }
  ]
};

const pc = new RTCPeerConnection(configuration);

• Simple interactive installation
• Basic STUN/TURN server configuration
• No SSL/TLS (suitable for basic setups)
• Automatic firewall configuration
• User credential management
• Uses IP as realm

• Ubuntu/Debian based system
• Root privileges
• Internet connection for package installation

1. Clone the repository:

git clone https://github.com/wwwakcan/coturn-setup.git

2. Make the script executable:

chmod +x coturn-setup.sh

3. Run the script:

sudo ./coturn-setup.sh

The script provides an interactive menu with the following options:

1. Install COTURN

   • Updates system packages
   • Installs COTURN server
   • Enables the service

2. Configure COTURN

   • Sets server IP address
   • Creates user credentials
   • Configures firewall rules
   • Generates configuration file

3. Exit

The script will configure COTURN with:

• STUN/TURN ports: 3478 (UDP/TCP)
• Alternative port: 5349
• UDP relay ports: 49152-65535
• No TLS/DTLS encryption
• Simple logging
• Basic authentication

After configuration, you'll receive:

Access Information:
----------------------------------------
STUN Server       : stun:YOUR_IP:3478
TURN Server       : turn:YOUR_IP:3478

Username         : your_username
Password         : your_password
Realm           : YOUR_IP

Supported Protocols:
- STUN/TURN UDP    : Port 3478
- STUN/TURN TCP    : Port 3478
----------------------------------------

This script configures COTURN without SSL/TLS encryption. It's suitable for basic testing or development environments. For production use, consider adding proper SSL/TLS configuration.
