Евгений, The number is a simple ratio of the number of targets with that port open divided by the number of targets scanned. The scanning took place in 2008, as described in the Nmap Network Scanning book here: https://nmap.org/book/port-scanning.html#most-popular-ports . We also did some filtering to remove obvious anomalies such as targets with no ports open or with enormous numbers of ports open. Coincidentally, I just sent an email to the list asking for port scan data in order to update these ratios: https://seclists.org/nmap-dev/2018/q4/3 Dan On Mon, Oct 8, 2018 at 4:28 AM Евгений Комянчин <komyanchin () gmail com> wrote:
Greetings! Could someone, please, tell about the exact formula used to obtain top-ports ratio in "nmap-services" file? Could not find one in documentation.
