Network Scanning Tool hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired by the ping(8) Unix command. It supports TCP, UDP, ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features. It can be used in many ways by people that dont care about security to test networks and hosts. It is one of the de facto tools for security auditing and testing of firewalls and networks.”]
