我创build了两个ec2实例，并能够ssh进入前两个罚款。 创build第三个后，我试图ssh到任何一个这个错误。
这就是我正在运行： ssh -v -i /Users/name/meteor.pem [email protected].###
要得到：

我试过这个post的build议：
sudo chmod 700 ~/.ssh/ sudo chmod 600 ~/.ssh/* sudo chown -R User ~/.ssh/ sudo chgrp -R User ~/.ssh/
但行chgrp -R User ~/.ssh/给我错误chgrp: mycomputerusername: illegal group name
我无法弄清楚组名应该是什么。 我的aws帐户用户名？
我也不知道我做了什么导致这个错误。 每次我创build一个新的chmod 600 meteor.pem我运行chmod 600 meteor.pem ，所以也许我input这行错了，这是造成权限问题？
任何有关下一步尝试的build议将不胜感激！
由于您在.ssh中使用700作为目录权限，600使用文件权限，所以不需要更改组。
从上面的日志中可以meteor.pem使用meteor.pem ，创build第三个EC2实例时是否使用了不同的密钥？
您可以使用aws-cli与ec2-fingerprint-key .ssh / key.pem（您的私钥/密钥名称的path）比较您的私钥指纹并与您的实例公共指纹
