Goldstein Lyor commented on SSHD-780:
-------------------------------------
The proper forum for such question is the {{[email protected]}} mailing list
and not the JIRA system. To answer your question - please read the [MINA SSHD
documentation|https://github.com/apache/mina-sshd/] regarding {{keepalive@*}}
handler (see [default registered handlers
section|https://github.com/apache/mina-sshd/#default-registered-handlers]). But
to answer your question briefly, I believe this feature is active by default.
The way it knows the server is alive is implicit - the
{{ClientConnectionServic#sendHeartBeat}} code sends such a request, and if the
server is non-response an exception will occur and thus terminate the session
> How does the HeartBeat work?
