I just exchanged email with David Filo this morning about this and it appears to have been a DoS attack using the usual array of stream/synflood tools. It also primarily hit the routers and FreeBSD 3.4 was largely unaffected (2.2 had some problems, but they were already in the process of upgrading those machines). There is some additional hardening work we can do here as a result of what was learned during the attack, however, and you should be seeing the relevant commits going into 4.0 shortly. - Jordan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
