Nmap

Information

• Nmap / “Network Mapper” is an open source utility for scanning and analyzing networks within the environment; the application’s primary function is for security probing and audits.

Cheatsheet

• You can replace all instances of {$ip_address} or 127.0.0.1 with the IP address that you want to scan.

• The total ports that will be scanned are from the range of 0 to 65535.

• Port 0 is not a specific binding port but rather a wild card port that tells the unix system to find and allocate the next available port.

• Scan UDP / TCP and all ports.

  • sudo nmap -sU -sT -p0-65535 {$ip_address}
