Increase SSH Connection Timeout in Linux

•  sudo vi /etc/ssh/sshd_config

        #ClientAliveInterval 

        #ClientAliveCountMax

• These config value will be used as timeout as below:

        Timeout value = ClientAliveInterval * ClientAliveCountMax

So if you want the timeout interval as 3600second, use below details in the config:

ClientAliveInterval  1200

ClientAliveCountMax 3

• Once you update the config reload ssh using below command

        sudo systemctl reload sshd
