Use the yum command to install the ec2-instance-connect RPM package.

The instance is running a relatively recent version of Amazon Linux 2: ~]$ uname -srv For the steps for Ubuntu, see Set Up EC2 Instance Connect. In this case, set up an Amazon Linux 2 instance running in your account. New Amazon Linux 2 instances have the EC2 Instance Connect feature enabled by default, so you can connect to those newly launched instances right away using SSH without any further configuration.įirst, configure an existing instance. Install RPM or Debian packages respectively to enable the feature. Currently, EC2 Instance Connect supports Amazon Linux 2 and Ubuntu. To get started using EC2 Instance Connect, you first configure your existing instances. Configuring an EC2 instance for EC2 Instance Connect Because the keys expire, there is no need to track or manage these keys directly, as you did previously. To connect to the instance successfully, you must connect using SSH within this time window. The SSH public keys are only available for one-time use for 60 seconds in the instance metadata. This script updates AuthorizedKeysCommand to read SSH public keys from instance metadata during the SSH authentication process, and connects you to the instance. When the EC2 Instance Connect feature is enabled on an instance, the SSH daemon (sshd) on that instance is configured with a custom AuthorizedKeysCommand script. You can also connect to your instances from a new browser-based SSH client in the EC2 console, providing a consistent experience without having to change your workflows or tools.

Ubiquitous access – EC2 Instance Connect works seamlessly with your existing SSH client.Auditability – User connections via EC2 Instance Connect are logged to AWS CloudTrail, providing the visibility needed to easily audit connection requests and maintain compliance.Instead, you generate one-time SSH keys each time that an authorized user connects, eliminating the need to track and maintain keys. This also allows you to move away from long-lived keys. They are only accessible by an instance at the time that an authorized user connects, making it easier to grant or revoke access in real time. Short-lived keys – SSH keys are not persisted on the instance, but are ephemeral in nature.

IAM policies and principals remove the need to share and manage SSH keys. Centralized access control – You get centralized access control to your EC2 instances on a per-user and per-instance level.You maintain the installed user keys, handle rotation, and make sure that the bastion host is always available and, more importantly, secured.Īmazon EC2 Instance Connect simplifies many of these issues and provides the following benefits to help improve your security posture: However, running bastion hosts comes with challenges. They provide logging and prevent rogue SSH access by adding an additional layer of network obfuscation. Some organizations also maintain bastion hosts, which help limit network access into hosts by the use of a single jump point. As a result, organizations have to store, share, manage access for, and maintain these SSH keys. When connecting to hosts via SSH, SSH key pairs are often used to individually authorize users. It was created in 1995 and is now installed by default on almost every Linux distribution. The most common tool to connect to Linux servers is Secure Shell (SSH).

While infrastructure as code (IaC) tools such as Chef and Puppet have become customary in the industry for configuring servers, you occasionally must access your instances to fine-tune, consult system logs, or debug application issues. Today, AWS is introducing Amazon EC2 Instance Connect, a new way to control SSH access to your EC2 instances using AWS Identity and Access Management (IAM).
