Hello,

On FreeBSD there is log_in_vain feature.

zuntum@zunix:~> grep vain /etc/rc.conf
log_in_vain="YES"               # YES to log connects to ports w/o listeners.

zuntum@zunix:~> tail -1 /var/log/all.log
Sep 23 16:54:49 zunix /kernel: Connection attempt to TCP 10.0.0.1:80 from 10.0.0.2:1529

Is something simmilar available on NetBSD? I'd like to log connections to ports
w/o listeners.
