Network Mapper

I always laugh at movies showing the hero/heroine hacking the computer/internet very easily without any effort. But it seems in the movie "Matrix Reloaded" Trinity had used proper hacking technique and tool in the hacking scene.

That tool shown in the movie is called Nmap. This is getting popular in the “network exploration/security auditing space” and its bundled with Redhat Linux, Debian Linux, Gentoo, FreeBSD, OpenBSD operating systems.

"Nmap ("Network Mapper") is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available. Nmap is free software, available with full source code under the terms of the GNU GPL."
