StunScan

StunCheck is a set of tools for scanning, testing and exploiting STUN and TURN servers.

Some of the implemented utilities are based on the fantastic Stunner application (https://github.com/firefart/stunner)

StunScan

Multithread STUN/TURN server scanner. It can scan large ranges of networks.

  -random                                    Randomize target hosts

StunInfo

Gets info about the stun or turn server like used software, listening interface and supported protocols.

 -= STUN info =-

options:
  -h, --help                                 show this help message and exit
