This is a simple way to create a more human looking course. It’s also a neat way to transition to scenarios. The Administration UI by default listens on all interfaces, and is protected by only basic authentication configured via the —htpasswd parameter. We strongly recommend putting the UI on SSL and IP limiting the clients that can connect. This function checks if limit has been exceeded and will exit. The CA public key is deployed to the client so that it can ensure it is communicating with the correct server. If these keys are not kept secure, anyone with MITM capability can intercept communications and take control of your clients. But you can override with the —dest_path option.
