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:
- 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 unix-like systems: Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOs X, Windows.
Earlier Hping was used as a security tool. Now it is used as a command-line oriented TCP/IP packet analyzer or assembler. You can use this for Firewall testing, advance port scanning, network testing by using fragmentation, TOS and different other protocols.
