title: Mobile Device identification using Nmap
body: <p>I am attempting to identify a mobile device on a LAN using Nmap, more specifically an Android smartphone. Both my laptop and the target (android smartphone) are connected to the same access point. I can ping the device etc. When I run a standard Nmap scan against the smartphone it says all 1000 ports are closed, which is odd considering I am browsing the web on the phone while the scan is running. With no ports being open, device discovery is very difficult. </p>
  
  <p>Is anyone aware of an efficient way to identify a smartphone on a network? Or can anyone explain this kind of behaviour from the mobile device?</p>
  
  <p>Thanks in advance</p>
