AWS SSH连接错误：权限被拒绝（公钥） [英] AWS SSH connection error: Permission denied (publickey)

问题描述

我试着用SSH连接到我的EC2实例和即时通讯越来越疯狂。我已阅读这篇文章，并尝试了所有用户的组合：

<一个href="http://stackoverflow.com/questions/1454629/aws-ssh-access-permission-denied-publickey-issue">AWS ssh访问权限被拒绝（公钥）的问题

它仍然不是为我工作。任何想法，我缺少什么？

更新：
 

据@aldanux建议：

 罗伯特@ Ubuntu的：〜/键$的ssh-凯基-R 54.72.242.0
＃主机54.72.242.0发现：4号线式ECDSA
/home/roberto/.ssh/known_hosts更新。
原来的内容保留为/home/roberto/.ssh/known_hosts.old
罗伯特@ Ubuntu的：〜/键$的ssh -i EC2-键pair.pem [e-mail]
警告：永久增加了ECDSA主机密钥的IP地址五四.72.242.0已知主机列表。
权限被拒绝（公钥）。
 

解决方案

试试这个步骤：

 的ssh-凯基-R 54.72.242.0

sudo的文件模式600 EC2键，pair.pem
 

然后：

 的ssh -i EC2-键pair.pem [e-mail]
 

Im trying to connect to my EC2 instance with SSH and Iḿ getting crazy. I have read this post and tried all user combinations:

AWS ssh access 'Permission denied (publickey)' issue

Its still not working for me. Any idea what am I missing?

UPDATE: 

According to @aldanux suggestions:

    roberto@ubuntu:~/keys$ ssh-keygen -R 54.72.242.0
# Host 54.72.242.0 found: line 4 type ECDSA
/home/roberto/.ssh/known_hosts updated.

roberto@ubuntu:~/keys$ ssh -i ec2-key-pair.pem [e-mail]
Warning: Permanently added the ECDSA host key for IP address '54.72.242.0' to the list of known hosts.
Permission denied (publickey).

解决方案

Try this steps:

ssh-keygen -R 54.72.242.0

sudo chmod 600 ec2-key-pair.pem

and then:

ssh -i ec2-key-pair.pem [e-mail]
