hansonhhr opened a new issue, #709: URL: https://github.com/apache/mina-sshd/issues/709
### Version Ssh client: mina 2.13.2 Ssh server: openssh 4.5p1 ### Description On the Server side, the sshd_config file is configured with `ClientAliveInterval 5` and `ClientAliveCountMax 3`. The client can successfully connect to the server, but after a few [keepal...@openssh.com](mailto:keepal...@openssh.com) requests (about 20 seconds), the connection will drop, but if I keep typing, the connection will stay. Scan the log I see the following message: 1. Server sends a [keepal...@openssh.com](mailto:keepal...@openssh.com) request to the client 2. Client returns SSH_MSG_CHANNEL_SUCCESS to the server 3. Server sends SSH_MSG_UNIMPLEMENTED to client 4. The connection is dropped after the server sends three SSH_MSG_UNIMPLEMENTED messages to the client Client log ``` 14:20:12.463 [main] INFO org.apache.sshd.common.util.security.bouncycastle.BouncyCastleSecurityProviderRegistrar -
