SSH-Keygen「そのようなファイルまたはディレクトリはありません」

Gitの公開キーを生成しようとしています。 Powershellを使用します。

PS>ssh-keygen -t rsa -b 4096 -C "[email protected]"
Generating public/private rsa key pair.
Enter file in which to save the key (//.ssh/id_rsa):
Could not create directory '//.ssh': Read-only file system
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Saving key "//.ssh/id_rsa" failed: No such file or directory

ファイルの場所を指定して実行した場合

ssh -vT [email protected]

使用する公開キーのカスタムの場所を確認しません

コマンドはキーを保存できませんでした。書き込みアクセス権がある場所でファイルを指定します。

ssh-keygen -t rsa -b 4096 -C "[email protected]" -f /path/to/key

これにより、秘密鍵が/path/to/keyに、公開鍵が/path/to/key.pubに保存されます。成功すると、エラーメッセージではなく、次のようなメッセージが表示されます。

Your identification has been saved in /path/to/key.
Your public key has been saved in /path/to/key.pub.
The key fingerprint is:
76:f7:82:04:1e:64:eb:9c:df:dc:0a:6b:26:73:1b:2c
The key's randomart image is:
+--[ RSA 2048]----+

+-----------------+

そして、sshがカスタムの場所でファイルを探すようにするには、-iフラグを使用します。

ssh -i /path/to/key -vT [email protected]

または、認証エージェントを実行している場合は、次を使用してキーをエージェントに追加できます。

ssh-add /path/to/key

キーがエージェントによって保存されると、次のことが簡単にできます。

ssh -T [email protected]

応答は次のようになります。

Hi USER! You've successfully authenticated, but GitHub does not provide Shell access.

そして、次のようにしてリポジトリをクローンすることができます：

git clone [email protected]:USER/REPO
