How do i fix this?? This message is intended as a diagnostic aid, and will certainly have its logging importance lowered in release versions of the kernel. This is one of the beasties that have had their logging importance increased in ALPHA test versions of the kernel to highlight kernel security and stability concerns. Basically it means that someone has sent a source routed packet to your machine, and it is logged for informational purposes rather than being dropped as was the case in production kernels. How do you fix this? You don't. You could enable source routed frames but this is not encouraged if you don't understand the message in the first place :-) Enabling these frames at the kernel level would certainly increase the vulnerability of your machine to attacks from the outside world.
