19Set the maximum number of keepalive probes TCP should send but get no response
20before dropping the connection. This option is usually used in conjunction
21with --keepalive-time.
22
23This option is supported on Linux, *BSD/macOS, Windows \>=10.0.16299, Solaris
2411.4, and recent AIX, HP-UX and more. This option has no effect if
25--no-keepalive is used.

27If unspecified, the option defaults to 9.
