How-to: Keep Shell Connection

It happens too often that I get disconnected from a shell connection after a while of inactivity with message Write failed: Broken pipe. To prevent this, simply put:

Host *
    ServerAliveInterval 30                 

in your ~/.ssh/config (OS X) or /etc/ssh/ssh_config (Linux) file.

This will make sure that null packet will be sent every 30 seconds (you can edit the interval) to the server to keep the connection alive.
