In case you are plagued by SSH connections dying in the worst moments and the following waiting period, here might be the solution to your problem.

Solution on your server

In /etc/ssh/sshd_config change or add the following lines:

ClientAliveInterval 30
ClientAliveCountMax 3

ClientAliveInterval will make your server ask the client whether it is still there and alive, every 30 seconds.
ClientAliveCountMax will try this 3 times if the client is not answering. After this 3 attempts, the server will close the connection.

Solution on your client

On the client it is basically the same. Only you have to replace “Client” with “Server”.

ServerAliveInterval 30
ServerAliveCountMax 3

To change these settings, update you ssh_profile with the entries.
