title: Using all UDP ports?
body: <p>On a mac, I do: </p>
  
  <pre><code>lsof -i udp
  </code></pre>
  
  <p>I notice a few entries for Skype.</p>
  
  <pre><code>COMMAND     PID USER FD   TYPE             DEVICE SIZE/OFF NODE NAME
  Skype       271 me   16u  IPv4 0xc1ff6619a243d125      0t0  UDP localhost:58148
  Skype       271 me   19u  IPv4 0xc1ff6619a243d745      0t0  UDP *:*
  </code></pre>
  
  <p>the first entry I guess tells me Skype is using the 58148 port.  What is the second entry saying <em>.</em>? </p>
  
  <p>It's using all ports on all machines. Hardly.</p>
  
  <p>Any help appreciated?</p>
  
  <p>Thanks.</p>
