问题描述
我正在尝试使用以下命令从shell SSH到Amazon EC2实例
ssh -vi sec.ppk ubuntu@ec2-xx.compute-1.amazonaws.com
但无法连接
这是上述命令生成的调试输出

为什么要要求密码短语sec.ppk
有什么问题有人可以帮忙吗？
忘了提及我使用具有上述相同凭据的FileZilla成功建立了连接
最佳答案
试试看
ssh -i /directory/keyname.pem ubuntu@ec2-xx.compute-1.amazonaws.com
.pem是您在设置实例时创建的密钥对文件。
次佳答案
对于不熟悉AWS的用户。 .ppk扩展与openSSH不兼容，因此仅适用于FileZilla /PutTTY。
在这种情况下，最简单的操作是安装PutTTY并使用putty-tools将.ppk转换为.pem。这是命令
sudo apt-get install putty
puttygen <path_to_key>/keyname.ppk -O private-openssh -o aws_key.pem
ssh -vi aws_key.pem ubuntu@<ip_address>
希望这对快速解决方案有所帮助。
