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.
If anyone at an educational institution tells you that send them to UCLA http://www.math.ucla.edu/misc/smurf.html or Simon Fraser University http://www.cs.sfu.ca/CC/Hypermail/cmpt-471/0008.html or the RFC archive at USC's Information Sciences Institute ftp://ftp.isi.edu/in-notes/rfc2267.txt or the Computer Emergency Response Team at Carnegie Mellon University http://www.cert.org/advisories/CA-98.01.smurf.html If those universities can handle the problem then all educational institutions should be able to fix this. -- Michael Dillon - Internet & ISP Consulting http://www.memra.com - E-mail: michael@memra.com
