After having read Nmap documentation (in french but the translation seems pretty accurate), a question arose:

Is it possible to use --version-intensity option (from the -sV option) when using the -A option ?

I'm asking because -A option integrates service/version detection (which correspond to the -sV option right ?) but in the documentation of -A option I can't see any reference to the --version-intensity option.

I hope I was clear in my explanation.

Yes, you can. Under the hood, -A is simply an alias for a number of other flags, including -sV which enables version scanning. User-specified control arguments are given precedence over defaults (if any) set by such flags.

As an example, -T4 sets a timing template including --max-rtt-timeout 1250ms, --initial-rtt-timeout 500ms, and --max-retries 6. However, you can manually specify any of these in addition to the -T4 flag to override these defaults.

  • So, just to be clear: nmap -A --version-intensity 9 would work ?

    Yes, that should work just fine.
