我想SSH入我的EC2实例，并获得以下ssh详细输出。 身份文件是pem格式，我认为是X.509。 我不知道login名，或者我可以用-l标志尝试。 在此之前，我只收到一个文件权限错误，因为文件具有不正确的权限，我更改为600，并将包含密钥的目录设置为700.密钥不在〜/ .ssh文件夹中，但在~aws-kes/aws-keys.pem
我运行这个命令：
$ ssh -v -i aws-keys/aws-keys.pem ec2...ompute.amazonaws.com
我得到以下输出：

编辑：我读了几个可能类似的问题，他们没有帮我:(
那么你需要提供用户名（login）和身份validation成功的私钥。
否则，它会尝试将您的当前（本地）用户名login。 所以，如果你不知道哪个用户名与你的密钥一起使用，你将无法使用SSHlogin。
我从社区AMI创build了一个新的Ubuntu实例。 我能够使用相同的命令ssh进入实例。 感谢所有帮助。
#ssh -v -i id_YWDRajat [email protected]上面的ref工作正常:)
