I don't understand how can u determine OS type from TTL, TTL will decrement
everytime it passed a router, what's the point for the hacker to keep track
of how many router it passed and it will change sometime??
Also OS finger-printing is not normally done by checking TTL, never heard
that you can use TTL to do a OS FP
