1.tcp_keepalive_time

int keepAlive = 1; Turn on the KeepAlive property. Default value: 0 (OFF)

int keepidle = 60; If there is no data interaction within 60 seconds, the probe is made. Default value: 7200 (s)

int keepinterval = 5; The detection packet is detected at a time interval of 5 seconds. Default value: (s)

int keepcount = 2; Number of probe retries. All timeouts determine that the connection is invalid. Default value: 9 (Times)
