What will be an ideal response?
LISTEN: The host is listening and ready to accept a connection on a port.
SYN SENT: The host sent a SYN packet.
SYN RECD: The host received a SYN packet and sent a SYN-ACK response.
CLOSE WAIT: The host received a FIN-ACK and sent a FIN-ACK. This might also indicate a passive close, when a server receives only the first FIN from a client (we show the process in its entirety here to be as explicit as possible).
