Tool - hping

November 28th, 2007 • Related • Filed Under

Wanna test your TCP/IP packet monkey skills? Well then you may like hping.

hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping 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 are:

• 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

Hping works on the following systems: Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOs X, Windows.
