Hi all,
I've read this interesting article:
http://www.packetstan.com/2010/09/openbsd-timestamps.html
The question is simple
¿Is there some way in FreeBSD to randomize the TCP timestamps as OpenBSD does
by default? I guess
some sysctl statement should do it, but I don't know.
The timestamps on FreeBSD for passive open are randomized as
long as you use SYN cookies (enabled by default). For passive
open they are not (yet) randomized.
