我知道它被问了很多次，但我无法得到问题的答案。 我正在尝试使用配置文件ssh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
当我运行以下命令时
$ ssh -v qa

尝试授予对文件的访问权限，但它们都不起作用。
但奇怪的是，当我做ssh user@<ip_address>它完美地工作。 有人能说出哪里出了问题以及出了什么问题吗
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及私钥，而不是公钥。
在配置文件中添加PreferredAuthentications publickey。无需使用.pub作为文件格式
例如：
Host github.com
HostName github.com
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
