“权限被拒绝（公钥、gssapi-keyex、gssapi-with-mic）”AWS .pem 提供

  • 772

我对此很陌生，它是我自己设置的第二台服务器，它应该简单明了，但我收到了这个错误。

环顾四周，但解决方案不符合我的情况。

即使我提供了.pem在 AWS 中创建实例时刚刚下载的文件，我也会收到此错误。

ssh -vvv -i ~/.ssh/transa.pem [email protected]

调试输出如下：

我有另一个.pem文件，我在另一个帐户中使用没有问题，两者都被加载到ssh-agentusing .bashrc，我不知道它是否与此有关。为什么一个工作正常而另一个不能工作，我怎样才能让它工作？

我在 Windows 10 上使用 Linux shell ( wsl)

ssh key-authentication

2 个回答

  1. Best Answer

    ec2 密钥对文件必须具有受限权限，您需要以管理员权限执行此操作。没有管理员权限，它可能不会显示任何错误。因此，您可能认为权限已更改。

    sudo su
chmod 400 ~/.ssh/transa.pem
    • 3

  2. 就我而言，这是因为我必须添加用户名。

    尝试在不使用用户名的情况下进行 ssh。

    $ ssh -vvv -i  ~/.ssh/aws.pem 52.88.251.23

Error message: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

    使用此（默认用户名ec2-user ）：

    ssh -v -i ~/.ssh/aws.pem [email protected]
