Connecting to EC2 Amazon using iTerm and .pub-file How can I setup my iTerm to connect my amazon server using the .pem file I have been given.

When I try ssh PUBLIC-DNS it returns Permission denied (publickey)..

EDIT

I have now tried the following without log, including a debug log:

Please note that I have removed the following informations SERVER IP, PUBLIC DNS and RSA KEY
ssh -i /path/to/keypair.pem user@host should do it.
