SSHキーによるサーバー認証に失敗しました

私のサーバー（CentOS）でプライベート/パブリックキー認証を設定しようとしました。ここで私が作った手順は次のとおりです。SSHキーによるサーバー認証に失敗しました

サーバーに公開鍵をコピーして、ファイル/root/.ssh/authorized_keys にcatコマンドでそれを付加しputtygenを
  • で公開/秘密鍵ペアを生成
    1. チェック
    2. は、（700）の.sshのファイルの所有権とアクセス権を示唆との.ssh/authorized_keysに（600）
    3. 、接続> SSH>認証の下にパテの設定でsshdサービス
    4. を再起動PRIVATキー
    を選択しました

    しかし、パテと接続しようとすると、「サーバーは私たちの鍵を拒否しました」というメッセージが表示されます。私はその後、パスワードを求められ、それが動作します。ここで

    はそれが機能しなかった理由です：

    私も認証ログレベルを上げ、ここで失敗したために出力されます。数多くのステップバイステップのチュートリアルが示すように、一つは、公開鍵ファイルを生成し、それをサーバにコピーしてから、このようなcatコマンドでファイルのauthorized_keysに公開鍵を追加する必要があります

    cat id_rsa.mypublickey.pub >> ~/.ssh/authorized_keys

    イム私の場合PuTTYgenを使ってキーを生成しました。しかし、結果として得られる公開鍵ファイル（保存ボタンを使用したときに保存されたもの）は、authorized_keysへの追加に構文上適用できませんでした。

    は正しいが公開鍵文字列を書式設定するには、&は、の〜/ .ssh/authorized_keysファイルにに1新しい行をPuTTYgenを窓から生成されたスニペットをコピー＆ペースト。正しいフォーマットされた行はこのように見えます、しかし、構文は、あまりにも、コメントなどを可能にする：

    ssh-rsa AAAAB3NzaEAAAAB/*...more letters...*/cPogeHB2XQBQ== rsa-key-20170831

    あなたはパテ以外のssh-エージェントで使用できる形式で秘密鍵を取得するには、次のことができPuTTYgenの変換オプションを使用し、キーをOpenSSH形式で保存します。提案ilanschユーザーとして
