title: How to display all data using tcpdump?
body: <p>I am capturing network traffic by using tcpdump. The problem  is: I can't see all capture data when the package is too long. For example, when the tcp frame length is more than 500, I just see 100-200 or less. How to display all frame data(500+)?</p>
  
  <p>I have tried add <code>-vv</code> and <code>-vvv</code> parameter. This is my current command:</p>
  
  <pre><code> tcpdump -i eth1 tcp and host 10.27.13.14 and port 6973 -vv -X -c 1000
  </code></pre>
