What is Nmap in termux?
Nmap is a free network mapping tool that helps you scan your network and
gather important data about it and the devices connected to it. To be a good
hacker, you need to know how to collect data about devices and networks, and
Nmap lets you do this with just a few commands. Nmap sends a packet to
collect data about a device and then analyzes the response to gather
information.
With Nmap, you can use a technique called Footprinting to gather extensive
information about victim networks and systems. You can scan networks to find
information about all connected devices, including their names and open
ports. Additionally, you can scan websites to find their open ports and even
discover their IP addresses. To learn more about Nmap, you can visit their
official site at Nmap.org.
