title: Tracking OSI packets with Wireshark
body: <p>All the 7 layers of the OSI model work together to define to the endpoint what is the type of machine he is dealing with.</p>
  <p>But I wonder why can't I detect a OSI packet with an software like wireshark? Because Wireshark should track every packet that goes to my machine, right? But I've never seen an &quot;OSI packet&quot; before.</p>
  <p>Am I doing something wrong? Is my concept of OSI packets right?</p>
