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 > How does the HeartBeat work? > ---------------------------- > > Key: SSHD-780 > URL: https://issues.apache.org/jira/browse/SSHD-780 > Project: MINA SSHD > Issue Type: Question > Affects Versions: 1.4.0 > Environment: jdk1.8.0 > Reporter: MayDay > > How does the HeartBeat work? > 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? -- This message was sent by Atlassian JIRA (v6.4.14#64029)
