But the point still remains that if you can't get the traffic out of the source network a smurf attempt doesn't work. Those "educational" sites which allow residence hall connections to launch this kind of thing deserve to be permanently black-holed from the Internet until they fix things. And yes, I know this means they'll have to spend money. Tough cookies. This is NOT an unsolvable problem (I can solve it with a $1,000 PC running IPFW between the residence hall Ethernet and the rest of the campus, or a few statements in a CISCO config) so people saying its an intractable problem are lying.
