AWS EC2 instance user name

When logging into an EC2 instance using SSH, you may receive an error. You check to make sure you have the right instance name, IP address, PEM key etc. but it still fails. You may be using the incorrect user name. The EC2 instance user names by OS are listed here:

For example, ubuntu servers are “ubuntu@” amazon is “ec2-user@” and other ones such as Debian are root@
