I think there is some confusion. I suggested the scanner (intruder.rs88.net) was attempting port 137 connections. The network being scanned does not have to have any NetBIOS services running for the scanner to look for them. Jason Lewis http://www.packetnexus.com It's not secure "Because they told me it was secure". The people at the other end of the link know less about security than you do. And that's scary. -----Original Message----- From: Jonathan Bloomquist [mailto:jsbloom () adelphia net] Sent: Sunday, May 27, 2001 4:33 PM To: info () lucretia ca; James Friesen; Simos Xenitellis; Jason Lewis Cc: INCIDENTS () securityfocus com Subject: Re: Scanning from a "intruder.rs88.net"?

This is simply MS services trying to do name searches using WINS resolution. Disable NetBIOS if you want to eliminate these messages. It woule be nice if these packets could turn themselves off past the router.
Huh? My firewall was also scanned by intruder.rs88.net (208.50.149.200) and I was not trying to perform any kind of WINS resolution. NetBIOS has no home on my network, either. The only port open on my firewall is 22. Maybe M[r/s]. intruder is scanning for ssh servers?
