Basic Scanning Techniques
| • Scan a single target | nmap [target] |

| • Scan an entire subnet | nmap [IP address/cdir] |
| • Scan random hosts | nmap -iR [number] |
| • Excluding targets from a scan | nmap [targets] –exclude [targets] |
| • Excluding targets using a list | nmap [targets] –excludefile [list.txt] |
| • Perform an aggressive scan | nmap -A [target] |
| • Scan an IPv6 target | nmap -6 [target] |
Discovery Options
| • Perform a ping scan only | nmap -sP [target] |
| • Don’t ping | nmap -PN [target] |
| • TCP SYN Ping | nmap -PS [target] |
| • TCP ACK ping | nmap -PA [target] |

| • ICMP address mask ping | nmap -PM [target] |
| • IP protocol ping | nmap -PO [target] |
| • ARP ping | nmap -PR [target] |
| • Traceroute | nmap –traceroute [target] |

| • Disable reverse DNS resolution | nmap -n [target] |
| • Alternative DNS lookup | nmap –system-dns [target] |
| • Manually specify DNS servers | nmap –dns-servers [servers] [target] |
| • Create a host list | nmap -sL [targets] |
Firewall Evasion Techniques
| • Fragment packets | nmap -f [target] |
| • Specify a specific MTU | nmap –mtu [MTU] [target] |
| • Use a decoy | nmap -D RND: [number] [target] |
| • Idle zombie scan | nmap -sI [zombie] [target] |
| • Manually specify a source port | nmap –source-port [port] [target] |
| • Append random data | nmap –data-length [size] [target] |
| • Randomize target scan order | nmap –randomize-hosts [target] |
| • Spoof MAC Address | nmap –spoof-mac [MAC|0|vendor] [target] |
| • Send bad checksums | nmap –badsum [target] |
Version Detection
| • Operating system detection | nmap -O [target] |
| • Attempt to guess an unknown | nmap -O –osscan-guess [target] |
| • Service version detection | nmap -sV [target] |
| • Troubleshooting version scans | nmap -sV –version-trace [target] |
| • Perform a RPC scan | nmap -sR [target] |
Output Options
| • Save output to a text file | nmap -oN [scan.txt] [target] |
| • Save output to a xml file | nmap -oX [scan.xml] [target] |
| • Grepable output | nmap -oG [scan.txt] [target] |
| • Output all supported file types | nmap -oA [path/filename] [target] |
| • Periodically display statistics | nmap –stats-every [time] [target] |
| • 133t output | nmap -oS [scan.txt] [target] |
Ndiff
| • Comparison using Ndiff | ndiff [scan1.xml] [scan2.xml] |
| • Ndiff verbose mode | ndiff -v [scan1.xml] [scan2.xml] |
| • XML output mode | ndiff –xml [scan1.xm] [scan2.xml] |
