linux - 无法通过 SSH 访问 EC2 实例 pem 'Permissions 0777 for ' .ssh/intuit-tke-qe.pem“太开放”

Question

我无法 ssh 进入我的 EC2 实例，似乎是我传递给 ssh 的 ssh .pem 文件的权限级别存在问题，谷歌搜索这似乎是许多其他人遇到的问题，但他们的解决方案对我不起作用。

这是我尝试过的，请有人帮忙......

尝试 1:

asemani$ ssh -i ~/.ssh/secure.pem root@54.210.0.1

尝试 2:

asemani$ ls -l ~/.ssh/

我不再收到警告，但权限仍然被拒绝。然后我还尝试对 .pem 文件执行 chmod 400 但这也不起作用。我不会将其粘贴在这里，因为这可能有点过分了。

这里发生了什么？如何通过 ssh 连接到我的 ec2？这应该是一件简单的事情？？

Answer 1

将权限更改为chmod 400 ~/.ssh/secure.pem
