nmap

nmap is short for Network Mapper. It is an open-source Linux command-line tool that is used to scan IP addresses and ports in a network and to detect installed applications.

nmap allows network admins to find which devices are running on their network, discover open ports and services, and detect vulnerabilities.

Commands

ping scan

Scans the list of devices up and running on a given subnet.

nmap -sP 192.168.1.1/24

scan a single host

Scans a single host for 1000 well-known ports. These ports are the ones used by popular services like SQL, SNTP, apache, and others.

nmap internet.aut.ac.ir

other scannings

  • stealth scan
  • version scan
  • aggressive scan

port scan

Port scanning is one of the most fundamental features of Nmap. You can scan for ports in several ways.

nmap -p 973 192.164.0.1
nmap -p 76–973 192.164.0.1

Verbose output

The verbose output provides additional information about the scan being performed. It is useful to monitor step by step actions Nmap performs on a network, especially if you are an outsider scanning a client’s network.

nmap -v scanme.nmap.org

Normal output

nmap -oN output.txt scanme.nmap.org
