Welcome to this hands-on AWS Learning Activity for troubleshooting EC2 connectivity issues.

The goal of this activity is to fix the broken environment and achieve the goal as outlined below. The first video in this activity presents the scenario and the goal, while the second video provides the solution (if needed). Do your best to solve the connectivity issue without viewing the solution video.

Goal: Fix the connectivity issue in the AWS environment so that you can update the YUM package installer (from the command line) on the provided EC2 instance (name "web server"). This environment has been created with security in mind, so the "web server" EC2 instance has been provisioned in a private subnet, and placed behind a bastion host and NAT gateway

The proper Linux command to update the YUM package installer is "sudo yum update".

To log into either of the provided EC2 instances, use the command: ssh linuxacademy@PUBLIC-IP-ADDRESS or ssh linuxacademy@PRIVATE-IP-ADDRESS
