Connect to instance

Amazon EC2 Instance Connect provides a simple and secure way to connect to your instances using Secure Shell (SSH).

Session Manager is a fully managed AWS Systems Manager capability that lets you manage your Amazon EC2 instances, on-premises instances, and virtual machines (VMs) through an interactive one-click browser-based shell or through the AWS CLI

EC2 Instance Connect

Instance ID i-0b95632df44dbd361 (ec2_ubuntu) Public IP address User name XXXXX

Session Manager

Session Manager usage: Connect to your instance without SSH keys or a bastion host. Sessions are secured using an AWS Key Management Service key. You can log session commands and details in an Amazon S3 bucket or CloudWatch Logs log group. Configure sessions on the Session Manager Preferences page.

ssh client

Instance ID i-0b95632df44dbd361 (ec2_ubuntu)

  1. Open an SSH client.
  2. Locate your private key file. The key used to launch this instance is kp_aws3in1.pem
  3. Run this command, if necessary, to ensure your key is not publicly viewable.
    • chmod 400 kp_aws3in1.pem
  4. Connect to your instance using its Public DNS:
    • ec2-52-14-183-130.us-east-2.compute.amazonaws.com


ssh -i "kp_aws3in1.pem" XXXXX@ec2-52-14-183-130.us-east-2.compute.amazonaws.com
