Goldstein Lyor commented on SSHD-780:
-------------------------------------

The proper forum for such question is the {{dev@mina.apache.org}} 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

> it only send keepAlive every interal time,but not to check the reply of the keepAlive timeout.
> how does the client know that the server is available.
> Or does other param need to set to make the client heartbeat work?
