Nmap's accuracy comes from a database that has been collected over the years through user submissions. It is very important that we help keep this database up to date. Nmap will let you know when you can contribute to the project by submitting an unidentified operating system, device, or service.
Please take the time to submit your contributions, as Nmap's detection capabilities come directly from the databases. Visit https://nmap.org/cgi-bin/submit.cgi? to submit new fingerprints or corrections.
