Server Refused Our Key
I've tried doing a keygen through PuTTY and adding the public key via nano copy and paste in ~/.ssh/authorized_keys , and also adding it through the Linode Dashboard. Every time I try to log on with the user and private key, I get a prompt saying "Server Refused Our Key", then a password login (which works fine). I'm lost as to what the issue could be, I've tried deleting the keys and making a new pair. I've made sure the chmod for the .ssh folder and 'authorized_keys' file is 700 and 600.

Used PSFTP to move a .txt file of the private key over to the .ssh/ directory, then renamed to 'authorized_keys'
Are you adding the public key when launching the new linode? Then you don't need to add it manually.
Try printing the contents of /var/log/auth.log for more details on the error.

I truncated the log before I logged back on via SSH. Also Fail2Ban is installed and my home IP is added to the ignoreip element in the jail.local file, I don't know if that's messing with it at all.
