Log into your instance from a Mac or Linux machine

You’ll need to do two things: first, set the permissions on amazon-key.pem:

chmod og-rwx ~/Downloads/amazon-key.pem

Then, ssh into your new machine using your key:

ssh -i ~/Downloads/amazon-key.pem ubuntu@MACHINE_NAME

where you should replace MACHINE_NAME with the public IP or hostname of your EC2 instance, which is located at the top of the host information box (see screenshot below). It should be something like or ec2-XXX-YYY.amazonaws.com.

Here are some screenshots!

Change permissions and execute ssh

Logging in is the starting point for most of the follow-on tutorials. For example, you can now install and run software on your EC2 instance.
