Hping3

hping3 is a network tool able to send custom ICMP/UDP/TCP packets and to display target replies like ping does with ICMP replies. It handles fragmentation and arbitrary packet body and size, and can be used to transfer files under supported protocols.

You can also use hping3 to test firewall rules, perform (spoofed) port scanning, test network performance using different protocols, do path MTU discovery, perform traceroute-like actions under different protocols, fingerprint remote operating systems, audit TCP/IP stacks, etc. hping3 is scriptable using the Tcl language.

Hping3 has a lot of modes and modules, I’ll leave it to you to use your creativity to scan a network using above help section of hping3.

Here is a example of hping3 doing simple ICMP Live Host Recon by the following command, Don’t forget to become a root user before using hing3.
