title: How to create a custom packet in c?
body: <p>I'm trying to make a custom packet using C using the TCP/IP protocol. When I say custom, I mean being able to change any value from the packet; ex: MAC, IP address and so on.</p>
  
  <p>I tried searching around but I can't find anything that is actually guiding me or giving me example source codes.</p>
  
  <p>How can I create a custom packet or where should I look for guidance?</p>
