Getting Started with Nmap on Kali Linux

Nmap is a powerful network scanning tool that can be used to identify and map network services, devices, and operating systems on a network. Kali Linux, being a popular distribution for penetration testing and digital forensics, provides a comprehensive environment to learn and practice using Nmap. In this article, we will guide you through the process of using Nmap on Kali Linux.

Prerequisites

Before you start using Nmap, make sure you have the following prerequisites:

  • Kali Linux installed on your system

  • A basic understanding of Linux commands and file permissions

  • A working internet connection

Installing Nmap on Kali Linux

To install Nmap on Kali Linux, you can use the following command:

sudo apt-get update

sudo apt-get install nmap

Basic Nmap Commands

Here are some basic Nmap commands to get you started:

  • -sS: This option scans for services using the SYN scan, which is a faster and more efficient way to scan for services.

  • -sT: This option scans for TCP services using the TCP scan, which is a more detailed scan that can identify services and their ports.

  • -p80: This option scans for services on port 80 (HTTP), which is a common port for web servers.

  • -p443: This option scans for services on port 443 (HTTPS), which is a common port for web servers.

Using Nmap to Scan a Network

To use Nmap to scan a network, you can use the following command:

nmap -sS -p80 -p443 <network_ip>
