(Hping is a tcp/ip packet assembly / analysis tool used on the command line. Its command mode is very similar to the ping command under UNIX, but it can not only send ICMP response requests. It can also support TCP, UDP, ICMP and raw-ip protocols. It has a route tracking mode and can transfer files between two mutually contained channels. Hping is often used to detect networks and hosts. It has very powerful functions and can run under a variety of operating systems, such as Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOSX, and windows.)
