title: How to send a SMB packet with Scapy?
body: <p>I'm using the scapy module for sending packets. My goal is to send a smb packet. But sniffing with Wireshark shows me that i'm sending a tcp packet and not smb.</p>
  
  <p>I'm using this template:</p>
  
  <pre><code>smb = IP(dst="...",src="...")/TCP(dport=...)/SMBNegociate_Protocol_Request_Header()
  </code></pre>
  
  <p>This packet is sent correctly but wireshark tells me it's simply tcp and not smb (in the protocol field), am i missing something?</p>
