Hping is a free packet generator and analyzer for the distributed IP protocol. It is one of the de facto tools for security auditing and the testing of services and networks.
Hping is a “Swiss Army knife” that generates virtually any IP, TCP or UPD packet. Hping can transmit a single packet, or multiple packets being sent at a specified rate or a maximal ‘flood’ rate. These features are possible because Hping opens ‘raw sockets’ injecting traffic directly to the network card and bypassing the operating system TCP/IP stack, with all its regulations and limitations. It is typically used in Linux but can also be used in Windows. Hping3 is the latest version.
Hping is used to run a UDP (–udp) flood (–flood) against a domain on port 80 (–dstport 80) with large packet size (–data 1400)
