title: MAC filtering using iptables/ebtables
body: <p>I'm trying to drop a MAC address on a node in my network. Now, I tried two tools iptables and ebtables, but both attempts failed:</p>
  
  <ul>
  <li><code>iptables -A INPUT -m mac --mac-source 00:0F:EA:91:04:08 -j DROP</code> resulting in "iptables: No chain/target/match by that name."</li>
  <li><code>ebtables -A INPUT -s 00:11:22:33:44:55 -j DROP</code> resulting in "FATAL: Module ebtables not found. The kernel doesn't support the ebtables 'filter' table."</li>
  </ul>
  
  <p>I'm working with Kernel version 2.6.32: <code>uname -r</code> results in "2.6.32-042stab049.6.emulab.1"</p>
  
  <p>How can I make (at least one) it work? I've searched about this failures, but not much information is to be found. How do I make the kernel support the ebtables 'filter' table? How come there is "no chain/target/match by that name"?</p>
