packet is sent when a
wants to connect on a particular port, but if the
, for some reason, does not want to accept the packet, it would send an
is used to end a TCP session. The packet is ACKnowledging receipt of the previous packet in the stream, and then closing that same session with a RST (Reset) packet being sent to the far end to let it know the connection is being closed.
