I have a custom client-server application both running on LAN(OS-Windows8). I used keep-alive option in the client and I see Keep alive packets in Wireshark. However, when I unplug the network cable of the machine the server is running on, I do not see any retransmission packets from my client to server but I see other applications sending retransmission packets to the server's IP. I don't understand why this is happening. Do I need to explicitly set retransmit timeout value or how else can I solve this issue?
For reference, this is the keep-alive code I am using. How to implement TCP KeepAlive in VB.NET on a TCP Client(socket)
I am calling setKeepAlive with values- SetKeepAlive(clientSocket, 60000, 10000)
Thank you
