[ale] hack attempts

[Jim Philips]

There may be a connection to my DNS issue here. When checking logs this 
morning, I found numerous attempts to log on to my system as bogus users 
coming in through ssh. Here are come log entries:

My first response was to remove openssh, since I don't really need it. 
Any further suggestions on checking to see if this goon got anywhere?
