我对Amazon EC2有点迷路了。我只是创建了一个实例并生成了一对密钥。我把它保存在我的win7硬盘上。
通过终端启动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。
当我通过putty尝试时，它回答Disconnected: No supported authentication methods available。
这是什么?
不知道您试图ssh进入的确切实例类型，但格式应该是"userid@ec2host.com" -您似乎正在使用实例id代替。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实例类型的默认用户。
