TCP reset attacks and the linux kernel.

[Naoki <naoki@xxxxxxxxxxxxxxxxx>]

Hi 'yall.

I just read this http://kerneltrap.org/node/view/3072, it details TCP 
reset (RST or SYN) attacks and has me sufficiently worried
enough to ask some questions.

I checked out the list of kernel tunable parameters with "sysctl -a" and 
found the option to disable window scaling but how do I change the 
window size from the default 64k to say 16k?

The next question is how can I set ( if it's not already ) my TCP stack 
to randomize source ports?



What does the Fedora community have to say in response to this 
potentially large problem?

Cheers!
