How to find the username of the instance launched in amazon-ec2?

Tags:

amazon-ec2

I m having trouble connecting to amazon ec2 instance using ssh. The key pair matches. On google-ing a bit i find that username is not the same for all instances. I assumed its always ec2-user. How can I find the username of the instance that I have launched?

I am getting this error:

Permission denied (publickey).

on trying this:

ssh -i test-instance.pem  [email protected]

Any help will be appreciated.

On the Home page, select DB Instances. The Instances page opens. Filter for the DB instance that you want the ID for. The instance details page opens and displays the ID.

Description-

Each Linux instance launches with a default Linux system user account. The default user name is determined by the AMI that was specified when you launched the instance. For Amazon Linux 2 or the Amazon Linux AMI, the user name is ec2-user. For CentOS, the user name is centos. For Debian, the user name is admin or root. For Fedora, the user name is ec2-user or fedora. For RHEL, the user name is ec2-user or root. For SUSE, the user name is ec2-user or root. For Ubuntu, the user name is ubuntu. Otherwise, if ec2-user and root don't work, check with your AMI provider.
