Re: Solution: Re: Huge smurf attack

Tracking down a smurf amplifier is not a problem. Getting the folks to fix it
is a little harder than it should be now, as most of the folks left with open
amplifiers have been notified and have to this point refused to fix or are unable to fix it.

The real solution is to catch the person starting the attack. Until the 'kiddies' start seeing
people paying a price for this, they aren;t going to stop. I could make sure every person on
my network is configured so that noone within their network is able to spoof addresses and can't be used
as an amplifier, but this will not protect me and my network from attacks aimed towards us.
As long as there are networks that allow spoofed addresses, we will be vulnerable. To even consider the fact
that every network will eliminate the ability to forge addresses it unrealistic. We can't get folks to stop being amplifiers, how are we going to get them to apply the spoof filters? The only solution
that is realistic is to start catching and prosecuting the individuals doing this. This requires total
cooperation between Tier 1 providers.. and the ability on all brands of routers to trace this.
This is not the case at this time, and I really don't see it heading that way anytime soon.
