+For example, connecting via SSH to {{{yourUserName@sb7.orbit-lab.org}}} will connect you to the console machine of "Sandbox 7".

-If you see an error or warning message while trying to SSH into a node, please read the message. Often times the message has to do with host keys on the node having changed from what the console expects (this is typically normal) because every image has a different host key, therefore it will change depending on what node and image you happen to be using. Follow the instructions in the message to resolve this.
