Hping is a free TCP/IP packet generator and analyzer created by Salvatore Sanfilippo (also known as Antirez) that is similar to the ping utility; however, it has more functionality than the sending of a simple ICMP echo request that ping is usually used for. Hping can be used to send large volumes of TCP
traffic at a target while spoofing the source
IP address, making it appear random or even originating from a specific user-defined source.
