TCP Packet Injection (2)

In Part 2 of the TCP packet injection video, we explain through the checksum routine and then construct some random data which we will send as the payload in TCP. After that we send the packet onto the network and use Wireshark to make sure all fields in the packet are valid and that the packet will be accepted by the destination.
