Hey there everyone! The series continues , here is part 2 of Information Gathering , if you have not read the Part-1 , see to it! This article will describe Nmap also called NetMapper , and it's use! In my opinion, Nmap is must-use tool for all Pen-testers/Hackers! It's over 20 years old tool! It have so many awesome utilities! FOLLOWING INFORMATION IS JUST FOR EDUCATIONAL PURPOSE, I'M NOT RESPONSIBLE FOR READER's ACTIONS AFTER READING THIS! Nmap uses raw IP packets 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. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X.
