Putty error: No supported authentication methods available.

So i can login withouth using ssh or rsa keys just using putty

look in /root/.ssh on your droplet, generate a new keypair with ssh-keygen and be sure copy the key to your machine. (It’s id_rsa not the one ending with .pub).

If you replace the public key on the droplet it doesn’t matter what happened to the old private key, though you should add the new public key to your keys list in the DO control panel so you can use it when you build droplets in future.

Heya,

You can ensure that the SSH server supports the authentication method you are using (e.g., password, public key).

• Disabled Password Authentication: Check that password authentication is enabled in /etc/ssh/sshd_config:

PasswordAuthentication yes

• Incorrect SSH Key Permissions: Ensure that your private key file permissions are set to 600 if you are using public key authentication.

Always restart the SSH service after making changes to the configuration:

sudo service sshd restart

Before testing from another machine with PuTTY, try connecting locally using:

ssh username@localhost

If the error persists, check the SSH logs for any issues:

tail -f /var/log/auth.log
