In SYN RECVD Receive RST(only server), I think it like this :From LISTEN To SYN RECVD,
I Recvive SYN,but I find RST in this Data,so I back to LISTEN,and to SYN SENT.

Now, From LISTEN to SYN SENT, Send data & SEND Ack, but I think send ack is a error,I think it should SEND SYN

Am I right? thank you!

Hi

Yes, there was certainly an error when moving from LISTEN to SYN SENT.

This has been corrected to SEND = SYN. The "send data" has been expanded to "App. send data" since a listener will typicllay stay in the listening state when a server, waiting for clients to connect. When the local application wants to send data it will then initiate this with the connection.

Thanks.
