[Snort-users] netbios-name-query

I get lots and lots of these, every day. Most of them are a 1 off scan of a single IP address. Some of them are misconfigured machines that try and use NetBIOS whenever they send us email :).

I mostly ignore them. If I get someone scanning the whole IP address range, I might fire off a complaint, but that's very rare.

I run snort 1.7 w/vision.conf from whitehats.com on fBSD 4.3 machine,
runs like a champ w/no probs!

I have recently, say within the last month, noticed an unusual amount of
'netbios-name-query' (port 137) scans
on my machine...at least 4/5 a day.

Should I be worried about this?

The scans are rarely across more than a couple of IPs in my /26 address
space and mostly originate from some dsl or cable
provider's network.

Has anyone else noticed this?  OR can someone provide comments?
