debug1: SSH2_MSG_SERVICE_ACCEPT received
debug1: Authentications that can continue: password,keyboard-interactive,hostbased
debug1: Next authentication method: keyboard-interactive
Why on the debug information, it does not have the pubkey option debug1: Authentications that can continue: password,keyboard-interactive,hostbased
I tried to update the ssh file .ssh/config
Host server-x IdentityFile ~/.ssh/id_rsa
On the server side, the pub key is saved in authorized_keys.
Solution
Why on the debug information, it does not have the pubkey option debug1: Authentications that can continue: password,keyboard-interactive,hostbased
Public key authentication isn't currently enabled on that host, otherwise you'd see publickey
in that list. Someone with root access on that server will need to update /etc/ssh/sshd_config
, making sure PubkeyAuthentication
is set to yes
(and not commented out), and then restart the SSHD daemon.
