This makes me feel better. I thought it odd that so many machines were 
hitting my ssh server. I even blocked it at the firewall for a day or 
so. Is anyone talking on what the bot system was that allowed them to 
automate this? It seemed that as soon as 1 got it so did a whole bunch 
more so obviously people are distributing lists of IP's for potential 
SSH access.

I'm not real sure on who to contact for these machines, but here are all 
the ones that have hit me. Mostly seem to be Asian so far.
