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? thanx, ~rob _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: http://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users **************************************************************************************** This message and any attachments are confidential to the ordinary user of the e-mail address to which it was addressed and may also be privileged.
