許可が拒否されました（publickey、keyboard-interactive）

Sshを使用してplanetlabノードに接続しようとしました。 Permission denied（publickey、keyboard-interactive）などのエラーがスローされます。これは何を意味するのでしょうか？例外の詳細は次のとおりです。

Authorized_keysファイルのアクセス権を再確認することをお勧めします。

$ chmod 600 ~/.ssh/authorized_keys

新しいSSHサーバーバージョンは、この点で非常に気難しいです。

リモートサーバーのsshd_configファイル（おそらく/etc/ssh/sshd_config内）を変更する必要があります。

変化する

PasswordAuthentication no

に

PasswordAuthentication yes

そして、sshdデーモンを再起動します。

サーバーは最初に公開鍵でユーザーを認証しようとします。それは機能しません（設定していないと思います）。そのため、「キーボードインタラクティブ」に戻ります。次に、パスワードを尋ねられますが、パスワードが正しくない可能性があります。パスワードプロンプトが表示されましたか？
