This is the pattern of the CodeRed virus that was going around the net a few
months ago. You are safe from it of course since it is targeted at windows
machines running unpatched versions of IIS.

Since it seems to come from a user in China I doubt there is anything at all you could do.
Even tring to get ahold of the system admins in China is very very hard. I
wouldn't worry about it at all it looks like a random scan of your domain and
from a client that is set up to scan whole ranges of addresses no worries.

It is most likely a random scan of an entire range of ip addresses so they are
just tring to find one out of the thousands that they do scan that is open to that hole. I wouldn't worry about random scans you have to start worrying when you see scans from the same host over and over attacking your machines in a human like way.

ssh question

Hi I was wondering if anyone can help me out with an ssh problem. I basically have numerous computers that I need to log into both as myself and as root. I know its possible using keys to set things up so that when I ssh from my main machine to another it uses the keys and I don't need to enter my password. I'm assuming this will be ok even with NIS/NFS running on all the machines? I've read a bunch of stuff online and tried using ssh-keygen and stuff, but can't seem to get the desired results. I guess if I can just start so I don't need to enter my password that would be great and then down the road, set up so root can do it?? Thanks.
