我对Amazon EC2感到有些失落。我刚刚创建了一个实例并生成了一对密钥。我将它保存在我的win7硬盘上。
我通过终端开始了一个ssh连接：
$ ssh -v -i EC2.pem instance_id@ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com
OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007

似乎不想让我进去。
当我尝试使用putty时，它会回答Disconnected: No supported authentication methods available。
这是什么？
感谢您的帮助。

不知道您尝试ssh的确切实例类型，但格式应为“userid@ec2host.com” - 您似乎正在使用实例ID。应该看起来像这样：
ssh -i my-key-pair.pem ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com
ec2-user是Amazon Linux的默认用户，ubuntu是所有ubuntu实例输入器的默认用户。
