Tips for conducting a Nmap scan. TCP SYN Scan nmap -sS [target] Timing Templates nmap -T [0-5] [target]
Basic Scanning Techniques TCP connect scan nmap -sT [target] Set the packet TTL nmap ttl [time]
UDP scan nmap -sU [target] [target]
Scan a single target nmap [target]
TCP Null scan nmap -sN [target] Minimum of parallel nmap min-parallelism
Scan multiple targets nmap
connections [number] [target]
[target1,target2,etc] TCP Fin scan nmap -sF [target]
Maximum of parallel nmap max-parallelism
Scan a list of targets nmap -iL [list.txt] Xmas scan nmap -sX [target] connection [number] [target]
Scan a range of hosts nmap [range of IP TCP ACK scan nmap -sA [target] Minimum host group size nmap min-hostgroup
addresses] Custom TCP scan nmap scanflags [flags] [number] [targets]
Scan an entire subnet nmap [IP address/cdir] [target] Maximum host group size nmap max-hostgroup
Scan random hosts nmap -iR [number] IP protocol scan nmap -sO [target] [number] [targets]
Excluding targets from a scan nmap [targets] Send Raw Ethernet packets nmap send-eth Maximum RTT timeout nmap initial-rtt-
exclude [targets] [target] timeout [time] [target]
Excluding targets using a list nmap [targets] Send IP packets nmap send-ip [target] Initial RTT timeout nmap max-rtt-timeout
excludefile [list.txt] [TTL] [target]
Port Scanning Options
