title: How do I get a specific range of packets from a large pcap file with tcpdump?
body: <p>I've got a huge pcap file (100GB) and I'm interested in a small number of packets which I know are numbers 5,000,000 to 5,000,020. </p>
  
  <p>How can I use <code>tcpdump</code> to read a pcap file, filter out packets by packet number (or range), and then write them out to a new pcap file?</p>
