If you are not a computer nerd, don’t bother reading this.
I’ve been struggling with getting my Backuppc setup working again. My documentation that I had used for previous setups wasn’t working. Specifically, logging into the client from my server via SSH without using a password. After many hours of tracking down what I was doing wrong, I finally figured out that the rsa keys stored in the ~/.ssh/authroized_keys2 have a new home. Since the release of SSH 3, the file it looks for is now just ~/.ssh/authorized_keys.
Any easy fix once I knew what was wrong
cp authorized_keys2 authorized_keys
