Not logging 137/udp is a good idea because it fills up the logs and does
not add any significant information to them.

Hi all,

Reading this thread, I notice something funny. Everyone says that logging 
blocked UDP 137 adds no useful information, and I understand where this is 
coming from. Windows boxes are so noisy when it comes to netbios, that it 
is best to just ignore it, or you'd have to worry about every 
misconfigured firewall out there.

 But on the other hand, this whole thread began with:
"I noticed an unusual increase in the amount packets coming for port 137" 
or something to that effect. Seems like some useful information can still 
come from logging it. In light of that, what do you think? Log less or 
more?

Regards,

P.S: Admin, sorry about the last two messages, I was having problems with 
the client :(
