Why can't I ssh into my new EC2 Instance?

I created a new instance (tiny, 64 bit AMI linux from Amazon) Created a new key pair called "mir". I downloaded mir.pem and put it in my ~/.ssh folder. I even did ssh-add mir.pem.

Then I tried to ssh ubuntu@public_DNS_from_amazon

Why doesn't it work!?

Try ssh [email protected] -i your-private.key, instead of ssh-adding the key.

Oh, and make sure you allowed TCP port 22 through the Security Group.

Does the security group (firewall configuration) allow SSH access?

More specifically - on the AWS management console page, select Security Groups in the left panel (towards the bottom) On the bottom-right panel, select "Inbound" tab, and make sure "Custom TCP rule" is selected. Enter 22 for the port number, click the "Add rule" button, then the "apply rule changes" button. No need to restart or reboot your instance, just need to enable TCP port 22 inbound

Try using either root or ec2-user as the username.
