+ | **hping3** 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. | ||
- | http://netcat.sourceforge.net/ | + | Like most tools used in computer security, hping3 is useful to security experts. |
+ | |||
+ | hping3 should be used to… *Traceroute/ping/probe hosts behind a firewall that blocks attempts using the standard utilities. *Perform the idle scan (now implemented in nmap with an easy user interface). *Test firewalling rules. *Test IDSes. *Perform DDOS attack *Exploit known vulnerabilties of TCP/IP stacks. *Networking research. *Learn TCP/IP (hping was used in networking courses). *Write real applications related to TCP/IP testing and security. *Automated firewalling tests. *Proof of concept exploits. *Networking and security research when there is the need to emulate complex TCP/IP behaviour. *Prototype IDS systems. | ||
