What is Nmap? Nmap, short for "Network Mapper," is a powerful open-source tool used for network discovery and security auditing. It is a network scanning tool that allows users to discover hosts and services on a computer network, identifying open ports, services running on those ports, and other information about the network. -sL : List scan - simply list targets to scan Example: nmap -sL targets.txt Explanation: This command performs a list scan, displaying the targets that would be scanned without actually scanning them. -sn : No port scan, just host discovery Example: nmap -sn target Explanation: This command performs host discovery without scanning for open ports. Useful for identifying live hosts on the network. -Pn : Treat all hosts as online Example: nmap -Pn target Explanation: This command treats all hosts as online, skipping host di...
