An opensource DNS reflection and amplification stress test.
Uses IPv4 UDP spoofing to send DNS request packets to DNS servers, which are amplified and sent back to the spoofed IP address.
Uses Nping (part of the Nmap package) to send custom udp packets. Be sure to have Nmap installed. Requries root to run.
Make sure to have permission of spoofed source ip network/computer and DNS servers.
Your NAT will block public spoofed source IPs inside a LAN.
