hping For Linux

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.

Here are some key features of "hping":

� Firewall testing � Advanced port scanning � Network testing, using different protocols, TOS, fragmentation � Manual path MTU discovery � Advanced traceroute, under all the supported protocols � Remote OS fingerprinting � Remote uptime guessing � TCP/IP stacks auditing � hping can also be useful to students that are learning TCP/IP.

What's New in This Release:
