Using Nmap
Nmap has a lot of features, but getting started is as easy as running nmap scanme.nmap.org. Running nmap without any parameters will give a helpful
list of the most common options, which are discussed in depth in the man
page. Users who prefer a graphical interface
can use the included Zenmap front-end.
