Keep an SSH Connection Open Through Even During Dormant Times

If you manage any Linux servers over the internet through ssh, you may have experienced your client disconnecting after times of inactivity.  I know I do and it annoys me to death.  There is a parameter you can add to the ssh connection in order to keep it up over these type of connections.  Just do the following:


ssh -o ServerAliveInterval=15 login@servername


The parameter -o ServerAliveInterval=15 adds the functionality of sending a heartbeat type message to the server every 15 seconds if data has not been sent in the last 15 seconds.  This parameter is customizable.
