As it’s already installed on most Linux/Unix-based distributions, you just have to execute the ‘nmap’ command from any terminal, and that’s it. Nmap is pretty easy to use if you’re familiar with command-line interfaces. The most popular method of using Nmap is via the terminal (command-line console), by performing a Nmap full scan command, but we’ll take a look into more examples below. This is done by waiting for packet responses to determine if ports are closed, open or filtered. Nmap is used by large companies as well as smaller-sized organizations for port auditing, host monitoring, penetration testing and similar tasks.Įven with Nmap constantly being updated with new features since decades, its core function remains as a port scanner, helping users gather data by sending packets to local or remote ports. Most of its functions are based on using IP packet analysis to detect and identify remote hosts, operating systems and services.
