nmap

 
Network exploration tool and security / port scanner. Some features only activate when Nmap is run with root privileges. More information: https://nmap.org.
 
  • Check if an IP address is up, and guess the remote host's operating system:
     
    nmap -O {{ip_or_hostname}}
     
  • Try to determine whether the specified hosts are up (ping scan) and what their names are:
     
    nmap -sn {{ip_or_hostname}} {{optional_another_address}}
     
  • Also enable scripts, service detection, OS fingerprinting and traceroute:
     
    nmap -A {{address_or_addresses}}
     
  • Scan a specific list of ports (use '-p-' for all ports from 1 to 65535):
     
    nmap -p {{port1,port2,...,portN}} {{address_or_addresses}}
     
  • Perform service and version detection of the top 1000 ports using default NSE scripts; writing results ('-oN') to output file:
     
    nmap -sC -sV -oN {{top-1000-ports.txt}} {{address_or_addresses}}
     
  • Scan target(s) carefully using 'default and safe' NSE scripts:
     
    nmap --script "default and safe" {{address_or_addresses}}
     
  • Scan web server running on standard ports 80 and 443 using all available 'http-*' NSE scripts:
     
    nmap --script "http-*" {{address_or_addresses}} -p 80,443
     
  • Perform a stealthy very slow scan ('-T0') trying to avoid detection by IDS/IPS and use decoy ('-D') source IP addresses:
     
    nmap -T0 -D {{decoy1_ipaddress,decoy2_ipaddress,...,decoyN_ipaddress}} {{address_or_addresses}}
