Re: PROBLEM: DoS Attack on Fragment Cache

[Matt Corallo]

Should the default, though, be so low? If someone is still using a old modem they can crank up the sysctl, it does seem 
like such things are pretty rare these days :). Its rather trivial to, without any kind of attack, hit 1Mbps of lost 
fragments in today's networks, at which point all fragments are dropped. After all, I submitted the patch to "scratch my 
own itch" :).
