while scanlogd can detect them, along with some other tools (scanlogd is
my personal favorite), you can't stop stealth scans, either, without a
packet filter that lets you block on the basis of arbitrary flags. ichains
doesn't have that capability, as i recall. (i use OpenBSD/ipfilter
firewalls, FWIW.)

detection is no good if all you can say is, "whoops... got nailed there."
may as well demand that you can block it, too.
