Pushback against DDOS Attacks

Huusker writes "Steven Bellovin and others at ATT Research Labs and ICIR have come up with mechanism to stop DDOS attacks. The idea is called Pushback. When the routers get flooded they consult a Unix daemon (/etc/pushbackd) to determine if they are being DDOS'ed. The routers propagate the quench packets back to the sources. The policy and propagation are separate, allowing hardware vendors to concentrate on the quench protocol while the white hats invent ever more clever DDOS detection filters for /etc/pushbackd. The authors of the paper have an initial implementation on FreeBSD."

Re:*BSD is dying

[Hektor_Troy]

Due to the troubles of Walnut Creek, abysmal sales and so on, FreeBSD went out of business and was taken over by BSDI who sell another troubled OS. Now BSDI is also dead, its corpse turned over to yet another charnel house.

Here's to hoping Microsoft picks up FreeBSD then.

"no operating system has ever come back from the grave"
I wasn't aware of that, but that's a good thing to hear. That means Windoze won't come back from the grave either. It died nearly a year ago. :)
