AWS - 无法通过SSH连接 - 我得到“权限被拒绝（publickey）”
问题描述：
我刚刚创建了和Ubuntu实例Amazon AWS。AWS - 无法通过SSH连接 - 我得到“权限被拒绝（publickey）”
在他们的指示，通过SSH连接（他们为您提供与您自己的paramters指令），他们说：
To access your instance:
Open an SSH client. (find out how to connect using PuTTY)
Locate your private key file (my.experiments.com.pem). The wizard automatically detects the key you used to launch the instance.
Your key must not be publicly viewable for SSH to work. Use this command if needed:
chmod 400 my.experiments.com.pem
Connect to your instance using its Public DNS:
ec2-13-58-23-167.us-east-2.compute.amazonaws.com
Example:
ssh -i "my.experiments.com.pem" [email protected]
然后，我做的：
$ ssh -vvv -i "my.experiments.com.pem" [email protected]
，然后我得到：

我做了他们推荐的东西：
$ chmod 400 my.experiments.com.pem
我也试图与Putty转换文件连接：用puttygen.exe但没有成功my.experiments.com.pem到my.experiments.com.ppk（腻子私钥）。用腻子，当试图连接时，我得到：Disconnected: No supported authentication methods available (server sent: publickey)在一个错误弹出窗口。

正如你可以在下面的图片上看到，该实例与密钥对推出：aws.playmeetup.com。
凡说：作为建议请确认您使用的是对应于你，当你启动实例选择密钥对的私钥文件。
答
你正在做的：
$ ssh -vvv -i "my.experiments.com" [email protected]
时应该是：
$ ssh -vvv -i "my.experiments.com.pem" [email protected]
+0
在*发布问题时，我犯了一个错误（就是这样）。我解决了上述问题。 – davidesp
答
所有的人都可以做的是做一个猜测，所以这里是我的：
您的屏幕截图显示了密钥对的名称是aws.playmeetup.com，但您已多次声明您尝试使用的密钥是my.experiments.com.pem。
这不是正确的关键。
所以你的工作站是Windows？ – gview
它是AWS的一个Ubuntu实例。这就是为什么他们给我上面的连接用户：'ubuntu'通过'SSH'连接。 – davidesp
@davidesp但你的工作站呢？我的意思是，你试图连接到EC2实例的操作系统是什么？ –
