Hacking/Security - NMAP Network Mapping Introduction

Find code and diagrams at: www.EliTheComputerGuy.com
NMAP allows you to map your network from the command line and output the results into a text format.
Make sure to run NMAP as root, or with sudo command. Root provides MAC Address and Vendor Information.
-A - Aggressive scan tries to find OS
-F - Scans only most popular 100 ports
-v - verbose output for command line
-oN - Outputs to Human Readable Text File
-oX - Outputs to XML file for Parsing
Examples:
sudo nmap -v 192.168.1.1
sudo nmap 192.168.1.0/24 -oN /home/username/nmap.txt
sudo nmap -A -F 192.168.1.0/24 -oX /home/username/nmap.xml

Best guide for NMAP I’ve ever seen in TH-cam. Great job, Eli!

[@dreamflair]

Thanks Eli. As a technician I run NMAP scans to assess vulnerabilities. Even though i run these scripts i don't create them so this break down really helps me better understand what I'm doing out here. Your material is practical and useful. I wish we had trainers like you in field. Thanks again!

When I run nmap, I enter sudo first but still don't see the MAC address or vendor

[@gamu3639]

Technically there is a gui for nmap I think is called zenmap.
