Nmap Tutorial in Hindi 🔥 Host Discovery & Port Scanning | Ethical Hacking Episode 29

Welcome to **GlobalTech Infosystems**! In Ethical Hacking Master Course Episode 29, learn Nmap fundamentals, host discovery, TCP port scanning, service detection, and scan-result analysis in simple Hindi with practical demonstrations. This beginner-friendly tutorial explains how network professionals use Nmap for authorized network discovery and defensive security auditing. What You Will Learn What is Nmap and how it works IP addresses, hosts, TCP ports, and network services Host discovery vs. port scanning Installing and verifying Nmap Preparing a local Python HTTP test server Scanning localhost with `127.0.0.1` Selecting specific ports using `-p` Understanding TCP connect scans with `-sT` Service and version detection using `-sV` Understanding `-Pn` and when it is used Checking the complete TCP port range on localhost using `-p-` Saving scan results with `-oN` Understanding open, closed, and filtered ports Troubleshooting unexpected scan results Ethical hacking interview questions Practical assignment for beginners Commands Covered `nmap --version` `nmap 127.0.0.1` `nmap -p 8004 127.0.0.1` `nmap -sT -p 8004 127.0.0.1` `nmap -sV -p 8004 127.0.0.1` `nmap -Pn -p 8004 127.0.0.1` `nmap p 127.0.0.1` `nmap -p 8004 -oN nmap_local_report.txt 127.0.0.1` Who Should Watch? Ethical hacking beginners IT support engineers System administrators Networking students Cybersecurity learners Linux and Python learners Students preparing for IT interviews Ethical Use Disclaimer This video is intended for education and authorized defensive security testing. Perform the practical exercises only on your own computer using localhost (`127.0.0.1`) or on systems for which you have explicit permission. Do not scan third-party systems or networks without authorization. Nmap results alone do not establish that a vulnerability exists.
