[lug] new port 445 MS vulnerability??

[D. Stimits]

All of a sudden, I am getting pounded (well, not too badly, but 
consistently) with IP addresses from all over the place looking to 
connect to port 445 tcp. They are harmless, nothing here is listening to 
445, but I have to wonder if there is a new MS vulnerability here, or if 
it is just a DDoS thing? Port 445 seems to be listed as microsoft domain 
service. Anyone else seeing this? I am pasting a list of addresses 
below, all of which were trying to get into port 445 at almost the same 
time.
