AWS EC2上でのscpについて

Question

現在、ちょっとしたメモをEC2からダウンロードしようとしているのですがうまくいきまん。
同じ様にはまってしまったことのある方よろしくお願いします。
pemはあっているはずなのですが、なぜno such fileとかになるんですか?
ssh -i "12345678.pem" [e-mail]

その、12345678.pemというファイルはどこにあるんでしょうか

[humuhimi]

返信ありがとうございます。
macブックを使っているのですが、/Users/****
Users以下にあります。つまり、ホームディレクトリにあります。

Answer 1

秘密鍵の置き場がパーミッション的に安全でない場合、そのようなエラーが発生する場合があります。

以下コマンドをまとめて実行し、適切なパーミッションにしてみてください。

cd $HOME
chmod 700 .
mkdir .ssh
chmod 700 .ssh
mv 12345678.pem .ssh/12345678.pem
chmod 600 .ssh/12345678.pem

以下で接続します。

ssh -i .ssh/12345678.pem [e-mail]

Answer 2

その、12345678.pemのファイル指定をフルパスで指定してやってみたらどうでしょうか
