The means of the LAND attack is that the attacker sends an SVN packet message with the same source and
destination addresses to the target host, the source port and the destination port are the same, and the receiver
waits for the final ACK packet to be sent , the connection is always in a semi-connected state, resulting in a
full limited TCP reception Waste of resources
