Cara Menggunakan NMAP IP dan Port Scanner di Ubuntu

Nmap (Network Mapper) adalah sebuah tools scanner keamanan yang awalnya ditulis oleh Gordon Lyon dan digunakan untuk menemukan host dan layanan di jaringan komputer, sehingga membuat peta jaringan. Nmap berjalan pada Linux, Microsoft Windows, Solaris, HP-UX dan varian BSD (termasuk Mac OS X), dan juga pada AmigaOS dan SGI IRIX [2] Linux. Adalah platform yang paling populer nmap dengan Windows berikut dengan cermat. Cara untuk install nmap di Ubuntu sangatlah mudah, cuma melakukan download dari internet :

to run nmap to scan ip address with range 10.10.28.0 – 10.10.28.254, you just run command :
zullfree@zullfree:~$ nmap -sP 10.10.28.0/24
and the result :
