1. Open a terminal on your system. You should be in your $HOME directory.

2. Copy the previously downloaded keyfile from the Downloads directory to the current directory.

   cp Downloads/AWSClearTestKey.pem .
   

3. Change the attributes of the AWSClearTestKey.pem using the chmod command as instructed in the dialog box shown in figure 11.

   chmod 400 AWSClearTestKey.pem

   ssh -i "AWSClearTestKey.pem" clear@ec2-34-209-39-184.us-west-2.compute.amazonaws.com
   

5. A message appears on the terminal stating the authenticty of the host can’t be established and prompts you with the message:

   The authenticity of host 'ec2-34-209-39-184.us-west-2.compute.amazonaws.com (34.209.39.184)' can't be established.
