         Yeap.  All our machines with external ssh access have had it 
appear at one time or another.  Interestingly it seems to come in 
waves.  We seem to be in a quiet part of the cycle at the moment, I expect 
it to liven up again towards the end of the week.  I have noticed that the 
list of usernames they're trying to connect with is slowly getting 
larger.  I've been wondering if thats a progression from finding accounts 
on compromised machines.
