Interesting link.

And no way to turn it off?  Makes me glad this machine is an old old quad 
core phenom. I haven't seen a thing I couldn't ID in wiresharks output.

But 3 of the other machines here, those running real machinery, are 
intel, 2-3 yo atoms, or 5-6 yo in a Dell Compact.  AMD stuff cannot do 
real time since about K6, which was tolerable, ran one for quite a spell 
till I replaced it with the atom stuff, reducing my power bill.

I would assume, if they are "calling home" that I could see the traffic 
with wireshark or tcpdump?  Hard to see in all the other traffic as I 
maintain an sshfs share, and an ssh login session to them all from here.  
So its pretty noisy in terms of net traffic here at the Heskett Cottage.
