Please be referenced to setsockopt(2) which describes a socket
option named SO_KEEPALIVE which asks to send packages without data
if a TCP connection is idle for the time interval specified by
tcp_keepalive_interval (in milliseconds). You'll find the Linux
equivalent in /proc/sys/net/ipv4/tcp_keepalive_time (in seconds!).
The common default is 2 hours.

See also RFC 1122, section 4.2.3.6.

Most of these parameters are explained at
