Hi, I'm trying to implement remote side network cable unplugging scenario by using keep-alive timer.
I set keep alive like: pcb->so_options |= SOF_KEEPALIVE; pcb->keep_idle = 15000; pcb->keep_cnt = 1; pcb->keep_intvl = 15000; >From wireshark, I can see my device is sending TCP keep alive packet. (Note: wireshark show with black color and marked as broken TCP.) And remote side didn't ACK my keep-alive packet. (remote side is windows XP OS with telnet.exe running. my telnet implementation work fine) so that my connection get keep-alive timed-out and disconnected. Is anyone get lwip work with keep-alive feature? Why remote side is not ACK-ing keep-alive packet? thank you very much. -- Bandu [email protected] -- Bandu [email protected]
