Especially for the 3rd row,what does 0
, FIN_WAIT1
, on
and (0.35/0/0)
mean respectively?
Best Answer
The 2 & 3rd columns are receive and send queues, respectively. (
0 2944
above) That's basically the number ofpacketsbytes waiting to be sent (2944) or received (0).FIN_WAIT is the standard TCP state of the open port. Specifically, that's an actively closed connection. (more info here) The client has sent its FIN packet, but hasn't received a FIN-ACK back yet.
The last column is a bit more complex. It's timer information related to the specific state the connection is in.
