A common question: When I access the JumpBox I get a scary warning dialog
The short answer: It’s normal and nothing to worry about. Just tell the browser to continue and everything will be fine.
The long answer: The JumpBox administration interface is served through an SSL encrypted connection so that your authentication credentials can’t be intercepted. Unfortunately, part of how SSL works is that it uses a certificate that is tied to the hostname for the system being accessed. In a JumpBox we have no way of knowing what the hostname or IP address will be in advance, so the certificate we use is considered suspect by the browser. The browser in an attempt to protect the user will throw up a warning dialog, sometimes multiple warning dialogs, with some scary language. Internet Explorer is particularly bad about the language that it uses. This is unfortunate because what we’re doing is completely harmless. In fact, the alternative (turning off SSL) is much worse. There’s actually no way for us to get rid of the dialogs that works across all browsers. We can either have encryption with the scary warnings, or no encryption with the possibility of admin credentials being captured from the network. The warnings are by far the lesser of two evils.
