Q&A
TeratermでVMware Workstation player上に構築したVM上に公開鍵認証でログインしたいのですが、ログインできません。
PW方式ではログインできるのですが、以下のようにエラーが出ます。
SSH2秘密鍵の読み込みに失敗しました
error:00000000:lib(0):func(0):reason(0)
エラーが表示されている画面です。
〇試したこと
・rootではなく、一般ユーザのホームディレクトリにも上記と同様に公開鍵を配置
・ユーザー名を空白、認証方式を「～鍵を使う」だけにチェックしOKを押下
・秘密鍵をTeratermフォルダに配置
設定ファイルやパーミッションは以下の通りです。

お手数ですが、ご教示お願い致します。

秘密鍵の読み込みに失敗しているので、その段階で、公開鍵やサーバー側設定について調べるのは無意味です。
秘密鍵にパスフレーズが付いているのでは？
あと、サーバー側の.sshディレクトリ以下のパーミッションが変です。公開鍵しか置いてないのでとりあえずは多分大丈夫なはずですが、秘密鍵を置く場合は自分自身以外から読み書きできないようにする必要があります。
