RSA 公開鍵認証による SSH 接続でエラーが出る場合の対処法

SSH コマンドの実行時、次のようなエラーが出る場合には、

Bad owner or permissions on /****/****/.ssh/config

以下のコマンドを実行してみてください。

$ chmod 600 ~/.ssh/config

また、例えば、以下のようなエラーが出た場合は、

Permissions 0777 for '/****/****/.ssh/id_rsa' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "/****/****/.ssh/id_rsa": bad permissions
****@****: Permission denied (publickey).

次のコマンドを実行します。

$ chmod 600 ~/.ssh/id_rsa

つまり、SSH の設定ファイルや RSA 秘密鍵に関しては、

アクセス権限がゆる過ぎても、パーミッションエラーになるということのようです。
