title: tcpdump always filters my packets
body: <p>I've been using tcpdump for about a month now, and recently, it has stopped capturing any packets that were not sent to or from the computer running tcpdump. I've stripped down my command to just:</p>
  
  <pre><code>sudo tcpdump -i en2
  </code></pre>
  
  <p>I've checked my interfaces with ifconfig, and en2 is in "PROMISC" mode. When specifying a specific host as a filter, I only see a few "arp" messages but nothing compared to what is actually going on in the network.</p>
  
  <p>Any ideas why this would be happening? Much appreciated if anyone can offer some advice!</p>
