What is Nmap network scanner

How To use Nmap

First let me start by saying i have Nmap install on my system but for people using termux type pkg install nmap this will install it on your termux as many os systems have it installed like Kali,parrot,cyborg hawk,black arch arch strike etc …

So see nmap full commands type Nmap in terminal or man nmap this gave you the manual for nmap in the terminal

some times when scanning you will be blocked this dont mean it dont work means the target not responding to the pings so if this happens use -Pn (eg nmap -Pn google.com and for IP’s nmap -Pn )

simple scan

so this a simple command for a simple scan for ips or a website its easy just type nmap
well you wont be using the local host so if its a website put the url or if its a ip type it.
