Re: Faking OS detection

[Franck Veysset <franck.veysset () rd francetelecom com>]

There was a tool call "FPF" (stands for FingerPrintFucker) that should
do what you want :
"BSD FingerPrintFucker is a kld for FreeBSD that changes the TCP/IP
stack in order to emulate other OS's against TCP/IP fingerprinting".

But I definitively not recommand using those kind of tool on a real
server !
Hope this help...
