What Is Nmap ?/*

Nmap (Network Mapper) is a powerful open-source tool used for network exploration and security auditing. It’s designed to discover devices and services on a computer network, thus creating a map of the network. Nmap can be used for tasks like port scanning, service version detection, and OS fingerprinting to assess the security of a network.

Most pentester and network administrators use this tool to scan networks and to find vulnerability , and also discover hosts , ports, services etc.

Nmap is mostly used by network administrator to identify what devices are running on their systems , to discover hosts , services , open ports and detecting security risks.

Some Basic Command Line

Host Scanning

List Of Host 

nmap -sL targets

Online Hosts Without Port Scanning

nmap -sn targets

For Only ARP Scanning 

nmap -PR -sn targets

To Discover Live Host

nmap -PE -sn targets [ PE – ICMP echo packets]nmap -PP -sn targets [ PP- ICMP timestamp requests
nmap -PM -sn targets [ PM – ICMP address mask request ]

Ping Scanning

TCP SYN Ping Scan 

nmap -PS22,80,443 -sn targets [ It will scan only three ports ]

TCP ACK Ping Scan

nmap -PA22,80,443 -sn targets [ It will scan only three ports ]

UDP Ping Scan 

nmap -PU53,161,162 -sn targets [ It will scan only three ports ]

To Ping A website 

nmap -sP www.google.com
It will show latency

Network Scanning

For Local Network Scanning

nmap 192.168.1.1/24
it will scan local network and also some open ports

For Aggressive Scanning 

nmap -A 192.168.1.1/24
it will provide some extra data . scan another website or scanme.nmap.org to learn

Port Scanning

To Scan A Single Port

nmap -p 80 192.168.1.1/24
80 ( its a HTTP port )

To Scan Multiple Ports

nmap -p 80,443 192.168.1.1/24
If you find this port open then its a webserver

Quick Scan 

nmap -F 192.168.1.1/24
It’s faster than normal scan. ( Basic Information )

Nmap Version 

nmap -V
