我正在尝试通过 ssh 进入我的 EC2 实例，并获取以下 ssh 详细输出。身份文件采用 pem 格式，我认为是 X.509。我不知道登录名，或者我可以尝试使用 -l 标志。在此之前，我只收到文件权限错误，因为该文件具有不正确的权限，我将其更改为 600，并将包含密钥的目录更改为 700。密钥不在 ~/.ssh 文件夹中，而是在~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：
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009

编辑：我阅读了一些可能类似的问题，但它们对我没有帮助：（
答案1
那么您需要提供用户名（登录名）和私钥才能成功进行身份验证。
否则，它会尝试使用您当前的（本地）用户名登录。因此，如果您不知道哪个用户名与您的密钥匹配，您将无法使用 ssh 登录。
答案2
我从社区 AMI 创建了一个新的 Ubuntu 实例。我能够使用相同的命令通过 SSH 进入该实例。感谢大家的帮助。
答案3
#ssh -v -i id_YWDRajat [email protected]上面的参考对我来说很好用:)
