I have a SSH key which is passphrase-protected. Authentication to the server is by SSH key only, password authentication is disabled. Both the server and my desktop run Ubuntu 14.04 and authentication with that key and server is tested and working.
My goal is to have
cron copy files from my desktop machine to the server via
rsync. I plan to create a new 'backups-user' (with limited rights) on the server, and have cron running on my desktop to copy the files to the server as this second user. That should avoid the issue of having to enter the passphrase for my primary SSH key.
My problem is that I keep getting "Permission denied (publickey)" errors when I try to
ssh-copy-id the second SSH key to the server.
Both SSH keys (public and private) were created and are in
~/.ssh/ on my desktop. The user 'backups-user' was created on the server, but I cannot log in as that user yet.
Am I going about this the wrong way, or is there a better method of automating what I want to do?
Here is the output of
