When I connected to a remote server via SSH on terminal app, I get the message: "Authenticity of host XXXXXXXX can not be established ... Are you sure you want to connect?" I type "yes", then: "Permanentry added XXXX to the list of known servers" David Pogue's Mac OS book says I should just say yes and go ahead. So I guess SSH is encrypting any data from then on, right? The language here is so confusing. At first I thought the question meant "youre connection to this server will always be insecure but SSH will never care about it from now on." Instead it means they've exchanged public keys and teh connection will be secure from now on, yes? I just want to make sure any connections after the first connection is secure since I'm dealing with a dedicated web server with root account. Thanks again for your help, you UNIX geeks!
