Yep. 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.
