New SSH Keys on Your Server?

I just learned a nifty little trick for updating your SSH keys when a server has changed them on you and you are being warned by ssh of a “man-in-the-middle” attack possibility…

ssh-keyscan -t rsa YourDomain.Com >> ~/.ssh/known_hosts
vi ~/.ssh/known_hosts

Delete the older entry – keep the new one. I just had to use this with my Dreamhost domains.
