Displays information about each TCP connection. The table includes the IP address, port
numbers, and state associated with each connection. The states are as follows:
Closed No connection exists.
Listen TCP is listening for a connection request.
SYN Sent TCP has requested a connection (SYN segment) and is waiting for the
remote TCP to acknowledge and match the request.
SYN Received TCP has sent and received a connection request and is now waiting for the
remote TCP to confirm.
Established The connection is open. Data can be received and sent. This is the normal
state for data transfer.
Fini Wait 1 TCP is waiting for the remote TCP’s request to terminate the connection
(FIN segment), or is waiting for the remote TCP to acknowledge a previous
request to terminate.
Fini Wait 2 TCP is waiting for the remote TCP’s request to terminate the connection.
Close Wait TCP is waiting for the client to request to terminate the connection.
Last Ack TCP is waiting for the remote TCP to acknowledge the connection
termination request sent previously. This request also acknowledges the
remote TCP’s request to terminate the connection.
Closing TCP is waiting for the remote TCP to acknowledge its request to terminate
the connection.
