I'm confused.. its still a DoS attack, eh??

It's the difference between:

A) Going out to your car at the end of a too-long day and finding a
broken taillight.

B) Going out to your car at the end of a too-long day and finding a
broken taillight and a business card under the windshield wiper that
has "Sorry - call me and I'll pay for it" written on the back.


I think the spoofed source filtering is more a red-herring than anything
else. Its not the fix for anything related to this problem of attacks on
the internet. Spoofed or non, I can forward 1,000,000pps at your network and
it will die (most times).

This is like trying to fix a rotten decayed tooth with trident.
