I generated the .pem with Openssl, then created the public key from the private key, pasted the public key into the user's settings on freenas, restarted sshd. Tried to connect with ssh using a config file and got this:

Config file for ssh client:
Code:
Host freenas
        HostName freenas
        Port 22
        User dan
        IdentityFile ~/.ssh/private.pem


I also tried generating a key using PuTTyGen and connecting via PuTTy as well as using Bitvise SSH, same results. I also generated the key files using ssh-keygen. I have password logins disabled on both the users and in the ssh service's settings.
