    Name        : coturn
    Product     : Fedora 32
    Version     : 4.5.2
    Release     : 1.fc32
    URL         : https://github.com/coturn/coturn/
    Summary     : TURN/STUN & ICE Server
    Description :
    The Coturn TURN Server is a VoIP media traffic NAT traversal server and gateway.
    It can be used as a general-purpose network traffic TURN server/gateway, too.
    
    This implementation also includes some extra features. Supported RFCs:
    
    TURN specs:
    - RFC 5766 - base TURN specs
    - RFC 6062 - TCP relaying TURN extension
    - RFC 6156 - IPv6 extension for TURN
    - Experimental DTLS support as client protocol.
    
    STUN specs:
    - RFC 3489 - "classic" STUN
    - RFC 5389 - base "new" STUN specs
    - RFC 5769 - test vectors for STUN protocol testing
    - RFC 5780 - NAT behavior discovery support
    
    The implementation fully supports the following client-to-TURN-server protocols:
    - UDP (per RFC 5766)
    - TCP (per RFC 5766 and RFC 6062)
    - TLS (per RFC 5766 and RFC 6062); TLS1.0/TLS1.1/TLS1.2
    - DTLS (experimental non-standard feature)
    
    Supported relay protocols:
    - UDP (per RFC 5766)
    - TCP (per RFC 6062)
    
    Supported user databases (for user repository, with passwords or keys, if
    authentication is required):
    - SQLite
    - MySQL
    - PostgreSQL
    - Redis
    
    Redis can also be used for status and statistics storage and notification.
    
    Supported TURN authentication mechanisms:
    - long-term
    - TURN REST API (a modification of the long-term mechanism, for time-limited
      secret-based authentication, for WebRTC applications)
    
    The load balancing can be implemented with the following tools (either one or a
    combination of them):
    - network load-balancer server
    - DNS-based load balancing
    - built-in ALTERNATE-SERVER mechanism.
