I got the following error:


    * Thanks for the submission, but (as noted on the submission page),
we are now only accepting second generation OS fingerprints. These are
generated by Nmap 4.20ALPHA6 and later. You can obtain the newest Nmap
version from http://insecure.org/nmap/dist/?C=M&O=D . If you have time,
please upgrade to this version and submit fingerprints for undetected
systems. We hope to grow the database so this system is much more
comprehensive and more accurate than the old detection system. The new
system is documented at http://insecure.org/nmap/osdetect/.

As can be seen I'm running 4.22.  Am I doing something wrong or is this
a bug?

The command was: nmap -vvv -O --osscan-guess -sSU <address>

I'm not 100%, but here's my guess:

You called Nmap with -O, which means it runs the 2nd Gen OS detection
and fallbacks on the 1st if it fails.  Maybe that's a 1st Gen
fingerprint rather than 2nd?

I would suggest running Nmap with -O2 and without --osscan-guess.  I
don't think --osscan-guess is to blame, but I'm not entirely sure
about that either.

Sorry I can only guess! :)
