Re: NMAP and MAC Addresses

Allow me to point out a few things which you are unaware of, apparently.

He is correct.  The tool you linked works SPECIFICALLY by using 
Microsoft's NetBIOS technology, as previous posters have stated is 
possible using nmap's scripting engine.  This ONLY works on hosts 
running a Microsoft operating system.  Deriving a MAC address from a 
host outside of your subnet is not possible using TCP/IP.  It's also 
technically possible to remote in using VNC and pull the MAC from the 
network properties, but THAT'S not going to be built into nmap or any 
other tool either!

Two points.  1. He's a CCIE, which is often referred to as "The 
doctorate of networking."  2. Given that he's emailing from a cisco.com 
email address, I'm willing to bet my paycheck against an ice cream cone 
that he knows more about this than you do; Cisco doesn't hire idiots.  
His response was completely accurate, whereas it's becoming increasingly 
apparent that you haven't got the foggiest idea what you're talking 
about-- which is fine.  What's not fine is your disturbing propensity to 
be a raging jerk about it.

You strike me as the kind of person who walks around the emergency room 
correcting the doctors on their diagnoses based on something you saw on 
an episode of House...
