OpenSSH has an option called ServerAliveInterval which can be used to
prevent the connection from being idle for too long (as a bonus, it will
detect when the peer died sooner even if the connection is idle).

autossh will monitor an ssh tunnel and restart it as needed.

While autossh helps to restart ssh session... what I find to be really
useful is to run the 'screen' command. It allows you to RESUME your ssh
sessions even after you disconnect. Especially useful if your connection
is not as reliable as it should be.
