Nmap online tutorial

About this course

This tutorial teaches you how to work in Nmap, a powerful network security tool. Nmap is the de facto standard for network mapping and port scanning and allows administrators to discover hosts and services on a computer network, and create a map of the network.


This tutorial is designed for people who want to learn more about Nmap – what it can be used for, how you can use Nmap to scan your network for open ports, how to interpret scan results, and such.


The tutorial is written for people with some experience in the world of networking. You should also have a basic understanding of Linux, since we will use a Linux distribution called Kali Linux for the examples in the course.

What you’ll learn

You will learn how to download and install Nmap on your Windows or Linux system. You will learn how to start an Nmap scan and interpret its results. We will also guide you through some more advanced Nmap usage, such as scanning UDP ports, adjusting delays between scans and such.
