You aren't aware of lots of things. As it stands, I suspect that a
large fraction of the network infrastructure could be brought down by
a sufficiently determined jerk with a single DS0 bandwidth circuit,
although things are not nearly as bad as they were a year ago. And no,
I'm not going to tell you how. And yes, I and the other real security
geeks *do* care and are trying to do our best to fix the situation.

You don't know what you are talking about. Let me rephrase that. You
REALLY don't know what you are talking about.
Might I sugest that you quit playing network and security engineer and
leave those of us who are trying to get work done alone?
