nmap is an easy to use network scanner that lets you discover hosts and services running on a computer.
One example of where the everyday user can utilize nmap is to use this command:
“`$ sudo nmap -sT -O localhost“`
This will show you the open ports on your computer. You may see things like 631/tcp for printer or 9050/tcp for Tor. However, you may also find some ports open you don’t intend to leave open.
nmap can be found in most repositories
