主机在PuTTY for Windows中使用SSH密钥时一直询问密码

Question

我正在使用PuTTY for Windows连接到梦想计算-VPS(梦想主机)。在梦想计算面板上，我创建了一个私钥并下载了它，一个.pem文件。使用PuTTYgen，我将该文件转换为SSH2-RSA格式的.ppk。所以，我下载了Pageant.exe并添加了这个.ppk文件。在PuTTY.exe，我把来自梦想计算面板的浮动IP作为主机名，在Connection->Data将用户名设置为dhc-user，最后在Connection->SSH->Auth加载.ppk文件。问题是当我打开连接时，身份验证过程一直在问我密码。我遗漏了什么？它不应该只是用户名和密钥吗？

Answer 1

主要问题是：

事件日志:服务器拒绝了我们的密钥

这可能是由于对.ssh/authorized_keys的权限不正确或密钥无效所致。

可以使用以下方法解决该权限：

chmod -R go-rwx ~/.ssh

另一种可能是钥匙错了。必须将公钥附加到~/..ssh/authorized_ key上，而不是私钥上。检查是否有正确的钥匙。
