Nmap Commands for Educational Use only.
Nmap is a network scanning tool used by system administrators, IT professionals, and students for security auditing, troubleshooting, and learning.
Common Scans
nmap -sP โ Ping Scan: Checks which devices are active on a network.
nmap -sS โ TCP SYN Scan: Helps discover open services.
nmap -sU โ UDP Scan: Finds active UDP services.
nmap -sV โ Version Detection: Identifies service versions for maintenance.
nmap -O โ OS Detection: Detects operating system type (for compatibility testing).
nmap -A โ Aggressive Scan: Runs multiple checks for detailed results.
Timing & Input
nmap -T4 โ Timing Template: Controls scan speed.
nmap -iL โ Input from List: Reads targets from a file (useful for admins).
nmap -sn โ Host Discovery: Finds devices without scanning ports.
Advanced TCP Techniques
nmap -sX โ XMAS Scan: Uses a special test packet to check responses.
nmap -sF โ FIN Scan: Uses a different method for host analysis.
nmap -sT โ TCP Connect Scan: Connects directly to services.
nmap -sN โ Null Scan: Uses empty packets to analyze responses.
nmap -sA โ ACK Scan: Helps detect firewall filtering.
Scripting & Port Options
nmap -sC โ Default Script Scan: Runs safe built-in scripts.
nmap --script <script> โ Run Specific Script: For detailed service checks.
nmap --top-ports <number> โ Top Ports Scan: Scans the most used ports.
Note:
These commands are meant for learning, ethical security research, and network administration only. Always use Nmap on your own systems or with proper authorization.
