"Remote Host Key Identification has Changed" error. How do I fix this?
This happens when the key stored on the machine you are connecting to has changed. This is to alert you of a possible man-in-the-middle attack. To fix this error and connect to the machine, run this command from a terminal prompt:
$ rm ~/.ssh/known_hostsOr you could remove a specific Entry with the ssh-keygen command. Check out How to remove/update a specific Host Key for more information.
