If you’re interested in working with Linux, you need to be able to understand the Secure Shell (SSH) service. SSH is used for hundreds of purposes from automation, to manual management, to deployment of new services. In this lab, you’ll be able to practice some configuration changes with SSH, including changing a node port and disabling `root` login.
