Forgive me if this just ends up in a stupid question, but having watched this thread for a while now, it strikes me as odd that noone has been able to trace the origin of any of these packets yet.
These packets are now widely known (and have been discussed on other lists, in the news etc, as well), and there are quite a few network admins aware of this.

Is it not possible for a few to get together and track down at least _one_ source computer?

It seems to me that you are all putting a awful lot of effort in logging and tracking and making statistics.
This is of course a good thing, but if we want to figure this thing out, there's more that need to be done.

I know.. spoofed addresses.. but that
does not mean we cannot trace packets to a certain extent. A shitty job, but unfortunately the only way of going about this, if we want to track it down for real.
Also, it seems from some posters that not all sources are spoofed.

Are you guys talking to your ISP's about this? I am sure the average ISP has at least one techhead that would be interested in digging a little in this, and I am guessing that several ISPs read this list as well. I'm not currently working as a network admin, so I'm not in a position to do much hunting in logs myself, unfortunately.  

So, what's happenin' dudes? Can we mount a common effort to track this down?
Any ISP techs reading this, who sees these packets coming out from their networks? Do you contact the "offenders"?

Cheers,
Anders :)
