hping is a network tool designed to send custom ICMP/UDP/TCP packets and to display target replies like ping. It handles fragmentation and arbitrary packet body and size, and can be used to transfer files under all supported protocols. Using hping, you can test firewall rules, perform spoofed port scanning, test net performance using different protocols, packet size, TOS (type of service), and fragmentation, do path MTU discovery, transfer files (even with really Fascist firewall rules), perform traceroute-like actions under different protocols, fingerprint remote OSs, and audit a TCP/IP stack. hping is very useful for learning TCP/IP.
