Which method to enable tcp_keepalive?
Only documented are tcp_keepalive_time & tcp_keepalive_probes
In Documentation/ip-sysctl.txt I read:
tcp_keepalive_time - INTEGER
How often TCP sends out keepalive messages when keepalive is
enabled.
But, it's unclear _where_ keepalive enabling is.
It is a part of the standard BSD socket API, how you enable it, and it
is done per socket. Use a call to setsockopt() to do it.
