使用 SSH 连接到 Amazon EC2 实例时禁用身份不明的主机确认
我正在使用 boto 和 Python 编写一个脚本来自动启动 Amazon EC2 实例并使用 SSH 与其交互。一切正常，除了每次建立连接时，SSH 都会提示我确认主机的真实性，如下所示：
The authenticity of host 'ec2-174-129-121-25.compute-1.amazonaws.com (174.129.121.25)' can't be established.
RSA key fingerprint is 26:09:bd:21:4f:55:20:3f:0d:fc:5f:cc:3e:08:30:db.
Are you sure you want to continue connecting (yes/no)?
我的 SSH 命令是：
ssh -i ssh2.pem [email protected]
由于每个 EC2 实例都是新主机，因此我每次都必须确认这一点，但我想无需任何用户输入的自动脚本。最好的解决方案是什么？
I am writing a script using boto and Python to automatically launch an Amazon EC2 instance and interact with it using SSH. Everything works fine except that every time I establish the connection, SSH prompts me to confirm the authenticity of the host like this:
The authenticity of host 'ec2-174-129-121-25.compute-1.amazonaws.com (174.129.121.25)' can't be established.
RSA key fingerprint is 26:09:bd:21:4f:55:20:3f:0d:fc:5f:cc:3e:08:30:db.
Are you sure you want to continue connecting (yes/no)?
My SSH command is:
ssh -i ssh2.pem [email protected]
Since every EC2 instance is a new host, I have to confirm this every time, but I want an automatic script without any user input. What is the best solution?

使用
-O StrictHostKeyChecking=no并可以选择设置 /dev/null 的KnownHostsFile（如果您想完全不安全的话）。但请记住，您正在绕过旨在保护您的安全措施！编辑，可能还有
CheckHostIP=no。man ssh并查看所有血淋淋的内容。Use
-O StrictHostKeyChecking=noand, optionally, set theKnownHostsFileof /dev/null (if you want to be totally insecure about things). But remember, you're bypassing security measures meant to protect you!edit and probably
CheckHostIP=notoo.man sshand see all the gory bits.对于 PuTTY 和 Windows，您可以使用
For PuTTY and windows you can use
