Automatically accept rsa fingerprint using pscp

Question

When you're using pscp to send files to a single machine is not a big deal because you will get the rsa fingerprint prompt once and never again after. But if you want to connect to 200 machines, you definitely don't want to type "yes" 200 times....

I'm using pscp on a Windows machine and I really don't care about the fingerprint, I only want to accept it. I'm using Amazon EC2 and the finger print change every time i restart the machines....

If there is a way to avoid it using pscp or a different tool please let me know!!!

Thanks!

On Windows you can use prefix echo y | in front of your command which will blindly accept any host key every time. However, a more secure solution is to run interactively the first time, or generate a .reg file that can be run on any client machine.
