Step-by-Step Tutorial: Setting Up Kali Linux and Running a Basic Scan

1. Download Kali Linux ISO from https://www.kali.org/downloads/
2. Create a bootable USB using Rufus or balenaEtcher for your preferred OS.
3. Boot your machine from the USB and follow the installation prompts.
4. Once installed, update Kali: sudo apt update && sudo apt upgrade -y
5. To scan a network with Nmap, open terminal and run:
nmap -sS 192.168.1.0/24
6. Review scan results for open ports and services.

Troubleshooting Common Issues

Tool not installing: Ensure dependencies are met and your OS version is compatible. Refer to official docs.
Network scans not detecting devices: Check network connectivity and firewall settings.
Permissions denied: Always run tools with appropriate privileges (e.g., sudo on Linux).
Tool crashes or freezes: Verify you have sufficient system resources and update to the latest version.
