Use EC2Rescue for Linux

EC2Rescue for Linux is an easy-to-use, open-source tool that can be run on an Amazon EC2 Linux instance to diagnose and troubleshoot common issues using its library of over 100 modules. A few generalized use cases for EC2Rescue for Linux include gathering syslog and package manager logs, collecting resource utilization data, and diagnosing/remediating known problematic kernel parameters and common OpenSSH issues.

The AWSSupport-TroubleshootSSH runbook installs EC2Rescue for Linux and then uses the tool to check or attempt to fix common issues that prevent a remote connection to a Linux machine via SSH. For more information, and to run this automation, see Amazon Web Services Support-TroubleshootSSH.

If you are using a Windows instance, see EC2Rescue for Windows Server.
