hping is a free packet generator and analyzer for the TCP/IP protocol. Hping is one of the de-facto tools for security auditing and testing of firewalls and networks, and was used to exploit the Idle Scan scanning technique now implemented in the Nmap port scanner. The new version of hping, hping3, is scriptable using the Tcl language and implements an engine for string based, human readable description of TCP/IP packets, so that the programmer can write scripts related to low level TCP/IP packet manipulation and analysis in a very short time.
Like most tools used in computer security, hping is useful to security experts, but there are a lot of applications related to network testing and system administration.

About this site
The aim of this site is to create a collaborative environment to document hping, share programming tips and hping scripts, and much more. Many topics can be discussed here, including topics related to security tools programming, Tcl, networking, as long as the author creates the wiki page and titles it appropriately.
The key point here is non-spam content of course, and to make sure contents are not copyrighted.
The moderator of this wiki is Salvatore Sanfilippo (aka antirez).
The Hping official site is at www.hping.org.
