Most Linux/UNIX machines have an SSH client, called a shell. On Mac OS, the shell application is called Terminal. In the shell, use the scp command to securely copy files to a Adobe Media Server on Amazon Web Services instance.
If your machine doesn’t have an SSH client, you can download one at http://www.openssh.org.
Use the ssh command to connect to an instance. Use the following syntax:
ssh -i keypair.pem amsadmin@public-dns

ssh -i /Users/AMS/Documents/amsdocs4.pem firstname.lastname@example.org
Log in to the Adobe Media Server instance as amsadmin.
