无法使用 git 配置文件进行 ssh

Question

我知道它被问了很多次，但我无法得到我的问题的答案。我正在尝试使用配置文件通过 ssh 连接到系统。配置文件是

Host qa
    HostName 10.218.70.345
    User user
    IdentityFile C:/Users/bean/.ssh/id_rsa.pub
    Port 22

当我运行下面的命令

$ ssh -v qa

尝试授予对文件的访问权限，但其中 none 有效。

但奇怪的是当我这样做时 ssh user@<ip_address> 它工作得很好。有人能告诉我哪里出了问题吗

Answer 1

您需要使用：

IdentityFile C:/Users/bean/.ssh/id_rsa

不是问题中的“id_rsa.pub”：您的配置文件必须提到 private 密钥，而不是 public 密钥。

Answer 2

在您的配置文件中添加 PreferredAuthentications publickey。并且不需要使用 .pub 作为文件格式

例如：

Host github.com
   HostName github.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/id_rsa
