麻烦连接到Amazon EC2上的SSH [英] Trouble connecting to Amazon EC2 over SSH
问题描述
我试图连接到我的亚马逊EC2实例。当您连接错误 - 权限被拒绝（公钥）。安装cmhod 400 myPem.pem文件没有帮助。 连接日志：

AMI创建和部署一个新的实例的一个新的PEM文件并没有帮助。
什么是需要做的，连接到服务器？
无法将主机添加到已知主机列表（/Users/oktolab/.ssh/known_hosts）
什么是 /Users/oktolab/.ssh/known_hosts ？
下面的命令来运行修复权限：
CHMOD 0600 /Users/oktolab/.ssh/known_hosts
另外，你能提供您所运行的确切SSH命令，因为：
阅读PEM私钥进行：类型RSA DEBUG1：身份验证，可以继续：公钥DEBUG1：没有更多的认证方法去尝试。权限被拒绝（公钥）。
如果你使用了大量的时间上面的错误出现 EC2用户而不是的Ubuntu 作为用户名和副反之亦然。在你的情况，这似乎是Ubuntu的图像，它应该是的Ubuntu 。这些东西将被澄清，一旦你提供确切的SSH命令，你正在运行
I'm trying to connect to my EC2 Instances on Amazon. When you connect an error - Permission denied (publickey). Installing cmhod 400 myPem.pem file does not help. Connection log:

AMI creation and deployment of a new instance with a new pem file did not help.
What's need to do to connect to the server?
Failed to add the host to the list of known hosts (/Users/oktolab/.ssh/known_hosts)
What are the permission for /Users/oktolab/.ssh/known_hosts ?
Run below command to fix the permission:
chmod 0600 /Users/oktolab/.ssh/known_hosts
Also, could you provide the exact SSH command that you are running because:
read PEM private key done: type RSA debug1: Authentications that can continue: publickey debug1: No more authentication methods to try. Permission denied (publickey).
A lot of time above error appears if you use ec2-user instead of ubuntu as username and vice-versa. In your case, this seems to be ubuntu image so it should be ubuntu. These things will be clarified once you provide the exact ssh command you are running
