Jul 10, 2020 · Every Amazon EC2 Linux instance launches with a default system user account with administrative access to the instance. If multiple users require access to the instance, it's a security best practice to use separate accounts for each user. Amazon EC2 enables you to specify additional AWS accounts that can use your Amazon Machine Images (AMIs) and Amazon EBS snapshots. These permissions work at the AWS account level only; you can't restrict permissions for specific users within the specified AWS account. For Amazon Linux variants, such as the Amazon ECS-optimized AMI, use the following command to install scp: [ec2-user ~]$ sudo yum install -y openssh-clients To transfer files in the other direction (from your Amazon EC2 instance to your local computer), reverse the order of the host parameters. Sep 17, 2019 · 1. From an SSH client, log in to your EC2 instance. Use one of the following user names: For Amazon Linux, the user name is ec2-user. For RHEL 5, the user name is either root or ec2-user. For Ubuntu, the user name is ubuntu. For SUSE Linux, the user name is either root or ec2-user. If ec2-user or root doesn't work, check with your AMI provider. 2.
I am looking for where the default Amazon AMI linux image sets up the privileges for the default ec2-user account. After logging in with this account I can use sudo successfully. Checking via the sudoers file, which I open by running visudo (with no other options) I see a few default settings and permissions for root ALL ALL

Use Key Pairs for Amazon EC2 Linux Logins For Amazon EC2 Linux instances, the default user name is ec2-user. The public key is stored on the target instance (the instance that the user is requesting access to) in the ec2-user home Jan 07, 2016 · As a casual gamer, and a user of a non-Windows machine, I find myself at a crossroads. When you spin up an instance on EC2, you base the instance on an “Amazon Machine Image”, or AMI. In ssh ec2-user@[ec2 instance ip] This morning I tried the same and couldn't connect. But doing. ssh -i ~/.ssh/[keypair name] ec2-user@[ec2 instance ip] gets me in. Using ssh-add on the key pair again gets me in. I'm guessing ssh-add only works within the shell I'd issued it in. When I closed the terminal window and opened another I no longer had

It is usually ec2-user but if you are using RHEL5 distro it can be root and if you are using the Ubuntu the user name will be ubuntu - which was my case. So alternatively try those: ssh -i my-pem-file.pem ubuntu@my-ec2-instance-address for Ubuntu. or. ssh -i my-pem-file.pem root@my-ec2-instance-address for RHEL5. Hope it helps! The config script is run by the user from the EC2 instance with root access. It installs Java onto the instance, fetches the startup script and sets it to run when the machine starts up. enables a user to log in to an Amazon EC2 Linux host with an SSH client, without having to enter a password.
