The connection is created using paramiko and is a persistent connection to the host. This class defines the methods for connecting to the node and configures the connection to send “keep alive” packets every 30 seconds. Because paramiko attempts to use SSH keys to establish a connection first, providing a password is optional. This session is utilized by InteractiveShells and cannot be interacted with directly.
