Linux CentOS SSH到AWS EC2实例崩溃/冻结

我正在尝试连接到运行AmazonAMI的AWSEC2实例

我已下载我的安全组密钥对并设置了正确的权限

chmod 400 ~/Downloads/keyPairFile.pem

然后我尝试通过公共DNS地址连接到ssh

ssh -v -i ~/Downloads/keyPairFile.pem ec2-user@ec2-ip.region.compute.amazonaws.com

我得到以下详细的输出

然而，我的Windows 7桌面上的Java客户端功能完美。

当webapp找不到您的pem文件时，这种情况似乎会发生。检查您的文件路径和语法，确保所有内容都是正确的。在我的mac电脑上，答案是使用前斜杠而不是后斜杠（如示例所示）。最终使用了：

/Users/david/Desktop/keypair.pem

您是否尝试从其他PC连接到此实例？您是否尝试使用密钥通过AWS的Java客户端连接到此实例？如上所述，我已经尝试了这两种方法，并且都挂起了。我也面临同样的问题。你能解决它吗？
