I hope this is the first in a long line of future patches meant to improve the accuracy of OS detection over IPv6. One patch is for the nmap tree and the other is for nmap-exp/luis/ipv6tests. The patch tries to guess the initial value of the field (255, 128, 64 or 32) and considers each one a distinct class. Additionally, in FPEngine.cc I switched from "external" declarations to including a generated header file. The header file (FPModel.h) is created same as FPModel.cc by the train.py script in Luis' folder. The reason is consistency in the size of the FPMean and FPVariance matrices.This is great! I've only read the diff, but it looks good to me.
You may have seen it already, but this wiki page gives some hints on working with the fingerprint files. The tools could stand to be improved. https://secwiki.org/w/Nmap/IPv6_OS_Integration David Fifield _______________________________________________ Sent through the dev mailing list https://nmap.org/mailman/listinfo/dev Archived at http://seclists.org/nmap-dev/
