RE: Detecting portscans

["Jenkins, Michael" <Michael_(_dot_)_Jenkins_(_at_)_disney_(_dot_)_com>]

With FreeBSD you can toggle a couple of variables
and have it log connections to unoccupied ports.

	sysctl -w net.inet.tcp.log_in_vain=1
	sysctl -w net.inet.udp.log_in_vain=1

It is an easy way to detect port scans without having
to install packet filtering.

Any chance of getting it added to OpenBSD?

Thanks,
Mike
