I'm using an old login with ssh-rsa public/private key and all was good.
I noticed that a couple of days ago the authorizazion was avoid with message "server refused our keys". After diggin' I figured out that the couple of keys stop working after exactly 5 years of their creation.
So I make a new pair of keys, take the public one, paste inside a file in ~/.ssh of the username that I'm using, converted it with
ssh-keygen -if and paste the new file into
authorized_keys but the I still get "server refused our key".
It's ok to copy and paste the real key without transfer it?
What I'm missing? This isn't my first time using a pair of keys and I follow the same procedure as described. I'm in doubt if I'm changing the correct
authorized_keys file but I've take a look in
/etc/passwd and see where is the home of the login which I'm using.
