It is currently effective on 21operating systems offering the `TCP_KEEPIDLE` and `TCP_KEEPINTVL` socket 22options (meaning Linux, recent AIX, HP-UX and more). Keepalive is used by the 23TCP stack to detect broken networks on idle connections. The number of missed 24keepalive probes before declaring the connection down is OS dependent and is 25commonly 9 or 10. This option has no effect if --no-keepalive is used. 26 27If unspecified, the option defaults to 60 seconds. 28
