--keepalive-time
Set the time a connection needs to remain idle before sending keepalive probes
and the time between individual keepalive probes. It is currently effective on
operating systems offering the TCP_KEEPIDLE and TCP_KEEPINTVL socket
options (meaning Linux, recent AIX, HP-UX and more). Keepalive is used by the
TCP stack to detect broken networks on idle connections. The number of missed
keepalive probes before declaring the connection down is OS dependent and is
commonly 9 or 10. This option has no effect if --no-keepalive is used.
If unspecified, the option defaults to 60 seconds.
