OS type
Hi every one.
I have scanned my server with nmap. It found what OS I am running, how can I block it ?

OS fingerprinting takes advantage of inconsistencies between implementations of TCP/IP, you can read more about it here.
Hiding or otherwise obscuring how packets are constructed in OpenBSD would be very pointless, security through obscurity is no security at all. Instead of trying to hide the fact that you use OpenBSD, be proud of it.

and if hiding what type of OS your machine is running is THAT important, just unplug it from the network!
