It is 21currently effective on operating systems offering the `TCP_KEEPIDLE` and 22`TCP_KEEPINTVL` socket options (meaning Linux, recent AIX, HP-UX and more). 23Keepalive is used by the TCP stack to detect broken networks on idle 24connections. The number of missed keepalive probes before declaring the 25connection down is OS dependent and is commonly 9 or 10. This option has no 26effect if --no-keepalive is used. 27 28If unspecified, the option defaults to 60 seconds. 29
