In the
book, , section , to quote “By default, Nmap scans the most common 1,000 ports for each protocol.” [1]However, the documentation did not mention the list of 1000 ports.
So, how to identify and show those 1000 ports ?
--top-ports n: the n highest-ratio ports found in nmap-services. n must be 1 or greater
-v: verbose level, to print the
-oG: grepable output
- : output to stdout
$ nmap --top-ports 1000 -v -oG - localhost
Note: refer to /usr/share/nmap/nmap-services
file for the service name and protocol.
So put all together, and process the output in ascending order:
$ nmap --top-ports 1000 localhost -v -oG - | grep 'Ports scanned' | cut -d" " -f4 | tr ',;' '\n'
The 1000 ports:
