amazon-web-services - AWS EC2 SSH : Permission denied (publickey)

Question

我已经配置了我的 EC2 实例，并通过 SSH 连接。但是当我使用端口规则创建一个新的安全组时，我无法再通过 SSH 访问。目前，我的自定义安全组规则是:

SSH   0.0.0.0/0
HTTP  0.0.0.0/0
HTTPS 0.0.0.0/0

当我尝试 ssh -v -i bodruk.pem ubuntu@ec2-54-149-134-92.us-west-2.compute.amazonaws.com我有以下错误:

OpenSSH_6.6.1, OpenSSL 1.0.1i 6 Aug 2014

已经尝试过 this solution ，但不起作用。我更改了两次 key 对并删除了 known_hosts 文件，但没有成功。

任何的想法？

您可以使用 ssh 端口远程登录到实例吗？ (远程登录“ip”“端口”)
如果可以telnet，那么问题可能出在Key Pair 或您的计算机上。如果不是，它可能与安全组和网络有关。
