I'm also not sure I understand your answer "This is the way TCP works".
When we disconnect the network cable the connection never times out (we
left it for at least 30 minutes).
TCP only disconnects quickly when a writer re-tranmits unacked data.
TCP never[1] disconnects when a reader waits for more data, this requires
an application timeout.
I agree it requires a time-out, but since we are in the openSSL library
(waiting for the hello message) there is nothing I can do in my application.
Is there a setting I can pass to SSL to tell it to time-out?
As for 'keepalive', I don't think that will help if the telnet session is
still connected (e.g. telnet will ack the keep-alive requests).
That's why you use non-blocking rather than keepalive.
