手がかりは乗数ですkey_load_public: No such file or directory。鍵を生成せずにサーバーが鍵を待っています。
ssh-keygenキーを生成してもう一度やり直してください。電話だけでは、ssh-keygenユーザーemarguliが続行できるようにRSAキーを生成します。
その他のオプションについては、以下をお読みください。マニュアルページ。
キーを生成したらアップロードする必要があります。人々クライアントの秘密鍵を信頼するようにリモートサーバーに鍵を送信します。通常、これは次のコマンドを使用して実行できますssh-copy-id。
$ ssh-copy-id <user>@<server>
ただし、ローカルシステムに接続するときは、RSA公開鍵を~/.ssh/id_rsa.pub認証された鍵ファイルに追加するだけです~/.ssh/authorized_keys。
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
最後に、最後のファイルに対する権限が正しいことを確認してください。そのファイルは所有者だけが書き込みできます。
chown 0640 ~/.ssh/authorized_keys
