Change SSH disconnect idle settings

On Linux or MacOS

Edit ssh config nano ~/.ssh/config or add when not exists.

Add following config properties

Host *
    ServerAliveInterval 60
    ServerAliveCountMax 8

ServerAliveInterval - Will send a keepalive message to server every x seconds to stay connected to it ServerAliveCountMax - How many missing responses form server can be before quiet connection. Default value is 3.

If you set ServerAliveInterval to 60 and leave ServerAliveCountMax as it is, this means the keepalive will only wait for 3 * 60 = 180 seconds = 3 minutes before quiting.
