: What sense can be made out of TIME_WAIT, CLOSE_WAIT, ESTABLISHED Using netstat command, I got the number of couple of TCP states of connections. But for running websites, how to make meaningful

@Caterina187

Hopefully this will help, detailed explanation here:-


CLOSED Indicates that the server has received an ACK signal (to
acknowledge receipt of a packet) from the client and the connection
is closed.
CLOSE_WAIT Indicates that the server has received the first FIN
signal (to acknowledge there is no more data to be sent) from the
client and the connection is in the process of closing.
ESTABLISHED Indicates that the server received the SYN signal
(synchronize, this signal is only sent in the first packet) from the
client and the session is established.
FIN_WAIT_1 Indicates that the connection is still active but not
currently being used.
FIN_WAIT_2 Indicates that the client just received acknowledgement of the first FIN signal from the server.
LAST_ACK Indicates that the server is in the process of sending it's own FIN signal.
LISTENING Indicates that the server is ready to accept a connection.
SYN_RECEIVED Indicates that the server just received a SYN signal from the client.
SYN_SEND Indicates that this connection is open and active.
TIME_WAIT Indicates that the client recognises the connection as active, but not currently being used.
