title: How to find the MAC address of a 'shutdown' system on local lan (is it possible?)
body: <p>How to find out the mac address of a system which is:</p>
  
  <ol>
  <li>Shutdown</li>
  <li>Power plugged in</li>
  <li>Connected to Lan</li>
  <li>Nic card ON.</li>
  </ol>

  <p><strong>Update</strong> 
  I am asking how to find out the mac address of some other system which is already shutdown.... and which is on lan.. </p>
  
  <p>I want to find out its mac from my system.... and to be clear... I want to tell that.. arp table can be populated by using ping .. i.e. if 172.16.3.12 is not in arp table then it can be added by just ping 172.16.3.12 <strong>but a system can be pinged only if its on</strong> ... a shutdown system can't be pinged...</p>
