Greetings and Salutations:
I *just* got my FreeBSD setup stable and working witha KDE GUI. :-). I know, easy for you guys but this is the first time I have set up FreeBSD with automatic updates. I settled on FreeBSD 5.4 after many tries.
I tried the Rose Attack / NewDawn against my laptop (it is a slow Pentium II 400 MHz Dell Inspiron 7000): http://digital.net/~gandalf/Rose_Frag_Attack_Explained.htm
Specifically: ../NewDawn4 1 <IP Address> 0 5 9999 99999999 4000 2
My machine locked up at pretty close to 100% when viewing the top command.
I asked a fellow worker who had a PIII 733 MHz to take a look and he reported about 70% CPU increase.
FYI. You might wish to take a look into this, IMHO this is a decent CPU DOS.

Works nicely if you have access to root on a local machine for lan use and the machines have been compiled with bpf support. Other then that my testing on these cases over the net "internet" have not yielded any proposed results to effect FreeBSD machines. Tried on 4.x & 5.x. Any other proof that this yields anything that we need to worry about?.
