我在 Windows XP 上。我遇到了奇怪的问题，因为当我尝试使用 bash ssh -v git@github.com连接到 git@github.com 时 ，我能够成功连接，但是当我尝试在同一台机器上通过 cmd 连接时，我是获取消息权限被拒绝。

在调试时，我发现在 bash 的情况下，ssh 正在检查 id_rsa 密钥，但在 cmd 的情况下，SSH 只是在检查 github_rsa。甚至没有尝试检查 id_rsa。以下是日志。

请提出可能的情况。有人建议检查我的密钥的文件权限。两个密钥具有相同的文件权限，即-rw-r--r--

以下是@naomi 提到的更改后的更新代码

两个密钥具有相同的文件权限，即 -rw-r--r--

您实际上让登录您的系统的人读取您的 id_rsa 私钥，这不好。实际上，您的 id_rsa 密钥应该具有 600 (-rw-------) 权限，这是通过发出chmod 600 id_rsa命令来完成的。此外，还要检查 .ssh 文件夹权限并将其设置为 700

在文件中查看

/etc/ssh/ssh_config

它可能有一个 github 条目，告诉它 id 文件在哪里。将此更改为您希望它使用的那个

如果这不起作用，您可以随时将 id_rsa 复制到 github_rsa ...
