ppk format keys are for putty only.

For OpenSSH you need to use OpenSSH format keys.

    I'm trying to connect to EC2 server, using .ppk file 

    ssh -i key.ppk -l root@dns-name

    The issue is that, the shell asks for passphrase ? i don't know what is it! Am able to use this key using putty, but not from linux

    Am I missing something here?

      Where did you get this key from? Can you go back to the source and ask for the passphrase?
