Service Version Detection
Basic Version Detection (-sV)
-sV)Explanation: This performs a version scan on open ports to detect the version of services running.
nmap -sV <target>Scan All Ports (--allports)
--allports)Explanation: This option scans all ports, including port 9100 which is often excluded by default.
nmap -sV --allports <target>Set Version Scan Intensity (--version-intensity <intensity>)
--version-intensity <intensity>)Explanation: Adjusts the intensity of the version scan, with a higher value using more probes for better accuracy but taking longer.
nmap -sV --version-intensity 9 <target>Light Version Scan (--version-light)
--version-light)Explanation: This is a lighter, faster version scan that uses fewer probes, possibly at the cost of accuracy.
nmap -sV --version-light <target>Scan Using All Probes (--version-all)
--version-all)Explanation: This attempts every single available probe, offering the highest likelihood of detecting services but taking longer.
nmap -sV --version-all <target>Trace Version Scan Activity (--version-trace)
--version-trace)Explanation: This option shows detailed debug output of the version scanning process.
