Hping2 is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired by the ping(8) Unix command, but hping isn't only able to send ICMP echo requests. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covert channel, and many other features. All header fields can be modified and controlled using the command line. A good understanding of IP and TCP/UDP is mandatory to use and understand the utility. While hping2 was mainly used as a security tool in the past, it can be used in many ways.
