They've made a big announcement about it, but the code doesn't yet
appear to be on their ftp site. The announcement does not describe
what approach they took to solving the problem (presumably something
more then their existing patch for the larg PCB hash table).  See
http://www.bsdi.com/press/19961002.html for the full announcement.

It scares me to think how much effort has gone into defense against
this one denial of service attack when there are endless possibilities
for other ones.

Colorado Springs, CO (October 2, 1996) -- Berkeley Software Design,
Inc. (BSDI) anounced today its enhancements to its BSD/OS and BSDI
Internet Server that are designed to protect against the recent wave
of "SYN-flooding" denial-of-service attacks. Beginning this week, BSDI
will make the source code for these enhancements available at no
charge via the Internet to BSDI customers as well as all interested
operating system suppliers, system administrators, and software
