我想连接到我的EC2实例并获得以下错误。AWS的权限被拒绝(公钥)

命令我运行命令ssh -v -i key.pem Ubuntu的@我的实例地址]

我改变了密钥文件的权限到600,因为我在其他线程所看到的,但没有解决问题。

输出我得到:

管理通过编辑/ etc/ssh_config中(在OSX)来解决它,并添加以下行:

ChallengeResponseAuthentication yes

一定要检查:

  1. 的SSH密钥对文件

  2. 用户名。例如:root,ec2-user,ubuntu,...

  3. 您的服务器的主机名。例如,如果你停止你的实例,它会得到一个新的IP地址。

如果您使用的是Ubuntu Cloud Guest官方图片,可以查看Ubuntu EC2 Starter's Guide

+1非常感谢。 pd:他们为什么不只是用一个单一名称来呼叫每个用户。 – BlaShadow 2013-09-29 01:24:31
