Suppose if you have defined your parameters as ClientAliveInterval 1200 and ClientAliveCountMax 4, then your connection disconnects after (1200*3)seconds if the client sends no response. The time out value will be Timeout value = ClientAliveInterval * ClientAliveCountMax When this limit is reached the SSH session terminates. The ClientAliveCountMax indicates the number of client messages that are alive, which was sent from the client without receiving any messages. ![]() Where the ClientAliveInterval indicates the time in seconds while the server was waiting before it sends a null packet to the client system to keep the connection alive. ![]() Now locate the below-given parameters #ClientAliveInterval You need to head over to the configuration file.
