Re: New snort install ipvar issue
From: James Lay <jlay () slave-tothe-box net>
Date: Fri, 24 Dec 2010 12:32:47 -0700

Thanks JohnŠnot running IPv6, but ehŠwhatever works.  Now it seems I've
muffed something as I get no alerts whatsoever even after doing an nmap on
it.  I did have 2.9.0.0 running fine on this, but now it seems nothing
causes an alert.  Anyone have any hints on why this would fire any alerts?
I even am testing ping outbound and inbound and nothing.  Config below:

Snort however gives me a big fat shove it when I try it:
