I have a collection of nmap subject fingerprints (described here), but have updated my local (private) reference fingerprint database since they were collected. Is there any existing way to re-match these subject fingerprints against the updated database without requiring a complete new scan? I've searched the nmap source code and haven't found anything yet.
There is not a public tool to do this, but you can cobble one together pretty easily with a few functions from
- Load the fingerprints from
- Parse the observed fingerprint you want to test with
- Check for a match with
- Print the results.
