Hi

I wonder if anyone successfully have configured OpenBSD to defeat the nmap
os-fingerprinting option.

I've tried using different option in pf, the OpenBSD packetfilter and by
using IPlog. Never made any success.There are several instructions based on
these techniques, but they don't seem to do the trick.

See,
