Scanning OpenBSD with NMAP - mysterious Results ???

["Johann Steigenberger" <office@admins.ws>]

Hi,

in the company i work, our security consultant told me OpenBSD would be the
most secure OS available ....
I´m quite new on OpenBSD but are very familiare with Linux.
Because i wanted to test, i scanned one of our OpenBSD boxes using
nmap -v -sS -O -P0
and got a very mysterious Result :

NMAP says : Difficulty 25374 (Worthly Challenge)

??????????????

This comes usually out if you would scan a win2k box :-)

At home i´ve a Linux Box with Kernel 2.0.39 wich shows a 9999999 (Good Luck)
even if
i do a scan on the localhost (without any filers)

As i told this to my boss he only laughted and sayed : find it out :-)
So my Question to you :

Why gets OpenBSD so poor Results ???

Thanks and Best Regards

Johann
