netipv4tcpkeepalivetime
The netipv4tcpkeepalivetime parameter is a kernel tunable that controls the idle time before TCP begins sending keepalive probes on a TCP connection. Keepalive probes are small packets sent by the TCP stack to check if the remote end of a connection is still responsive. If no data has been exchanged on a connection for a period specified by netipv4tcpkeepalivetime, the kernel will start sending these probes. This parameter is measured in seconds.
If the remote end does not respond to a keepalive probe after a certain number of retries,
Adjusting this value can have implications for network resource usage and application behavior. A shorter keepalive
The netipv4tcpkeepalivetime parameter is part of the Linux kernel's TCP/IP networking stack and can be modified
