ubuntu – AWS连接错误：权限被拒绝(publickey)

对不起,如果这听起来多余,但相信我不是.我已经尝试了几乎与此问题相关的大多数链接,但到目前为止我没有任何工作.我甚至试过这篇文章二.以下是我到目前为止所尝试的内容

>密钥400的许可以及600
> ubuntu作为用户名因为它的Ubuntu 14.04
> IP是正确的,我甚至尝试过公共DNS
>键附加到实例
>使用FireFox浏览器的AWS Java客户端(MindTerm).但是当我按下输入时它会显示我对抗我的IP这一行时出错.即使我很幸运,它只会询问我给ubuntu的用户名然后退出给出错误“I / O错误 – 读取失败：未知错误”或者只是让我回到IP步骤.

我在这个问题之前做的最后一件事就是2天前我尝试使用此链接http://www.krizna.com/ubuntu/setup-ftp-server-on-ubuntu-14-04-vsftpd/在我的客户端上安装FTP服务器.不幸的是,这个链接没有按预期工作,我最终在FTP登录中没有成功.今天当我尝试使用我的密钥对登录时,它给了我错误.

下面是我的ssh尝试的日志
