我有一个托管在远程共享服务器上的网站。我在Windows上，正在尝试从Git Bash命令行SSH到我的主机。我通过cPanel创建了一个大小为4096的新RSA密钥并对其进行了授权。我下载了公钥和私钥，并将密钥添加到我的ssh配置文件中：
IdentityFile ~/.ssh/mykey_rsa
当我发出命令ssh -vvv user@something.com时，我收到错误。

如何解决此问题？更重要的是，如果没有完整的基于Unix的命令行工具，我如何在Windows上这样做呢？基本上我的工具是Git Bash，Windows命令行，cPanel，我可以通过Filezilla或Windows命令行FTP到我的服务器。
