我在 cygwin 的帮助下安装了 openssh 作为服务本教程
我可以从 cygwin ssh 进入 localhost。
但是，当我尝试从 putty 执行此操作时，出现“服务器拒绝我们的密钥”错误。
在设置过程中，id_rsa和id_rsa.pub在 .ssh 文件夹中生成。
我获取id_rsa文件，将其导入 puttygen 并生成private.ppk文件。
我在 putty 中创建了一个会话来使用私钥。
当我尝试登录时，系统提示我输入用户名。输入用户名后，系统出现“拒绝我们的密钥”错误，并尝试使用密码验证。
我将不胜感激任何帮助。
编辑：
如果有帮助的话，以下是从 cygwin 成功通过 SSH 连接到 localhost 的输出

该程序为您当前登录的用户ssh-user-config生成一个 SSH 密钥对（~/.ssh/id_rsa和），并且如果您愿意，还将其添加到，其中可能指的是或。~/.ssh/id_rsa.pub~/.ssh/authorized_keys~/cygdrive/c/cygwin/homeC:\cygwin\home
因此，您需要以运行时的同一用户身份登录ssh-user-config。（这是两者都不 cyg_server也不是sshd，它们是用于 SSH 登录过程的特殊账户。)
