SSH access from Mac

1.) Open up your Terminal client

Open up Finder. Go to Applications > Utilities, then open up the app called Terminal

2.) Verify where your Key Pair is

By default, your Key Pair should be in your Downloads directory. Verify that it's there by pasting the following command:

ls ~/Downloads/[MY KEYPAIR NAME].pem

Make sure you replace [MY KEYPAIR NAME] with the name you gave your keypair. For example, if I made a Key Pair called banana-smith-keypair, then my command should look like this:

ls ~/Downloads/banana-smith-keypair.pem

3.) Change the ownership of the key pair file.

Remember: this keypair is your way of logging into your instance! Therefore, it needs to be accessible only by you. We do this by executing the following command:

chmod 600 ~/Downloads/[MY KEYPAIR NAME].pem

Again, you need to make sure that you replace [MY KEYPAIR NAME] with your Key Pair's name. So for banana-smith-keypair, we would paste:

chmod 600 ~/Downloads/banana-smith-keypair.pem

4.) Copy your instance IP or URL

Remember how we made a note of the Public IP of your EC2 instance? Now we need to use it. Essentially, what we want to do is to login to the IP of the instance using the Key Pair we created. Put it in your clipboard, or make a note of it in Notepad.

5.) Login!

Finally, we login to the instance. We do this with a command that looks like this:

ssh ec2-user@[MY IP ADDRESS] -i ~/Downloads/[MY KEYPAIR NAME].pem

Assuming we have a Public IP of 22.22.22.22, and we have a Key Pair called banana-smith-keypair, your command would look like this:

ssh [email protected] -i ~/Downloads/banana-smith-keypair.pem
