Thanks for visiting the fingerprint submission page! We greatly
appreciate OS and service fingerprint submissions and corrections, as
they are the only way we could ever hope to collect such a diverse
database of thousands of operating systems and applications.
Submitting new (undetected) OS or service fingerprints:
Sometimes Nmap is completely unable to determine the OS of a target
machine or version details of a service, so it spits out an OS or
service fingerprint. If you know what is actually running, please
submit the fingerprint with the appropriate form:
Submitting corrections when OS detection guesses wrong
Occasionally Nmap will report an OS guess which you know is
wrong. The errors are usually minor (such as reporting a machine
running Linux 2.4.16 as "Linux kernel 2.4.8 - 2.4.15"), but there have
been reports of Nmap being completely off (such as reporting your web
server as an Applewriter printer). When you encounter such problems
(minor or major), please report them so everyone can benefit. The only
reason the Nmap DB is so comprehensive is that thousands of users have
spent a few minutes each to submit new information. Please report
corrections as described on the Nmap
OS detection correction page
Submitting corrections when version detection guesses wrong
If the Nmap version detection results for a target host are wrong
(even just slightly), please notify us so that everyone can benefit
from the correction. We have posted simple
instructions for correcting inaccurate version detection results.
Thanks for contributing to the Nmap community and helping to make OS and version detection even better!
