Network auditing tool
hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to 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 covered channel, and many other features. While hping was mainly used as a security tool in the past, it can be used in many ways by people that don't care about security to test networks and hosts. A subset of the stuff you can do using hping: - Test firewall rules - [spoofed] port scanning - Test net performance using different protocols, packet size, TOS (type of service) and fragmentation. - Path MTU discovery - Files transfering even between really fascist firewall rules. - Traceroute like under different protocols. - Firewalk like usage. - Remote OS fingerprint. - TCP/IP stack auditing.
