   @coderZoe @tomaswolf Hi, I meet a problem related to the ssh keepalive.
   My task failed seems due to the ssh channel closed, I am not sure if this is due to the heartbeat miss.
   
   ```
   exceptionCaught(ClientSessionImpl[cebwmapp@/10.227.23.69:16022])[state=Opened] IOException: Connection reset by peer
   ```
   
   My code is look like below
   ```
   SshClient sshClient = SshClient.setUpDefaultClient();
   sshClient.start();
   
   ClientSession session = sshClient.connect(
                       sshConnectionParam.getUsername(),
                       sshConnectionParam.getHost(),
                       sshConnectionParam.getPort()).verify(timeout).getSession();
   String password = sshConnectionParam.getPassword();
   if (StringUtils.isNotEmpty(password)) {
       session.addPasswordIdentity(password);
   }
   String privateKey = sshConnectionParam.getPrivateKey();
   if (StringUtils.isNotEmpty(privateKey)) {
       KeyPairResourceLoader loader = SecurityUtils.getKeyPairResourceParser();
       Collection<KeyPair> keyPairCollection = loader.loadKeyPairs(null, null, null, privateKey);
       for (KeyPair keyPair : keyPairCollection) {
           session.addPublicKeyIdentity(keyPair);
       }
   }
   if (!session.auth().verify(Duration.ofSeconds(timeout)).isSuccess()) {
       throw new RuntimeException("Session auth failed");
   }
   session.setSessionHeartbeat(SessionHeartbeatController.HeartbeatType.IGNORE,
           Duration.ofSeconds(PropertyUtils.getInt("session-connection-heartbeat-interval", 5)));
   return session;
   ```
   
   Do I need to add KeepAliveHandler.INSTANCE in globalRequestHandlers to avoid this?
