Why are two keypairs both allowing access to my EC2 instance based on a custom AMI?

Depending on how you create the AMI (bundle or using rsync), you can remove or omit $HOME/. Ssh/authorized_keys for the user ubuntu and root.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
