SSH-Keygen"没有这样的文件或目录"

Question

试图为我的git生成一个公钥.使用Powershell.

PS>ssh-keygen -t rsa -b 4096 -C "my@emailaddress.com"
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

如果我给文件的位置并运行

ssh -vT git@github.com

它不检查要使用的公钥的自定义位置

Answer 1

PS>ssh-keygen -t rsa -b 4096 -C "my@emailaddress.com"
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

该命令无法保存您的密钥.在您具有写入权限的位置指定文件:

ssh-keygen -t rsa -b 4096 -C "my@emailaddress.com" -f /path/to/key

这将保存您的私钥/path/to/key和公钥/path/to/key.pub.成功后,您将看到以下内容,而不是错误消息:

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]----+
|        o        |
|       o .       |
|        +        |
|       + +       |
|        S o .    |
|       . = = o   |
|        E * + o  |
|        o.++ o   |
|         *o..    |
+-----------------+

然后,要ssh在自定义位置查找文件,请使用以下-i标志:

ssh -i /path/to/key -vT git@github.com

或者,如果您正在运行身份验证代理,则可以使用以下命令将密钥添加到代理:

ssh-add /path/to/key

代理存储密钥后,您可以执行以下操作:

ssh -T git@github.com

响应应该类似于:

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

您可以继续使用以下命令克隆存储库:

git clone git@github.com:USER/REPO

Answer 2

对我来说，该ssh-keygen命令似乎仅在使用 cmd 时才会失败：

您的身份信息已保存在 [...]/.ssh/id_rsa 中。fdopen [...]/.ssh/id_rsa.pub 失败：没有这样的文件或目录

生成了私钥，但创建了 0 字节的公钥文件。

如果我在 Windows 上的 Git Bash 中运行该命令，它就会起作用。

Answer 3

这对我来说工作：ssh-add '/home/user/.ssh/id_rsa'
