Scanning Tools

# Host discovery
nmap -sn 192.168.1.0/24              # Ping scan (no port scan)
nmap -sL 192.168.1.0/24              # List scan (DNS resolution)
nmap -Pn 192.168.1.100               # Skip host discovery

# Port scanning techniques
nmap -sS 192.168.1.100               # TCP SYN scan (stealth)
nmap -sT 192.168.1.100               # TCP connect scan
nmap -sU 192.168.1.100               # UDP scan
nmap -sA 192.168.1.100               # ACK scan (firewall detection)

# Port specification
nmap -p 80,443 192.168.1.100         # Specific ports
nmap -p- 192.168.1.100               # All 65535 ports
nmap -p 1-1000 192.168.1.100         # Port range
nmap --top-ports 100 192.168.1.100   # Top 100 common ports

# Service and OS detection
nmap -sV 192.168.1.100               # Service version detection
nmap -O 192.168.1.100                # OS detection
nmap -A 192.168.1.100                # Aggressive (OS, version, scripts)

# Timing and performance
nmap -T0 192.168.1.100               # Paranoid (slowest, IDS evasion)
nmap -T4 192.168.1.100               # Aggressive (faster)
nmap -T5 192.168.1.100               # Insane (fastest)
