I wasn't aware the SMURF used source-routing. It generally simply spoofed the source address of the packet. If more ISPs properly filtered on the customer edge back then, SMURF wouldn't have been as deadly as it was/(is).

my mistake. when smurf was first explained to me lo those many years ago, the person who explained it (and it's been so long i don't even remember who that was) claimed it used source routing. i never really questioned that, but everyone who has corrected me is right -- it doesn't need source routing to work. oops, richard -- Richard Welty rwelty@averillpark.net Averill Park Networking 518-573-7592 Unix, Linux, IP Network Engineering, Security
