Hehe - I knew I shouldn't have been trying to send coherent email out
at midnight. I've attached the originally ommitted advisory. From
what I've seen looking around the net, protecting against SYN attacks
usually involves mods to one's router or enabling SYN cookies in the
kernel. I could be wrong though. Anyone have any thoughts or
comments on this?
