About this Hands-on Lab

In this hands-on lab, we will connect to a server and install Webmin. Once Webmin is installed, we will change the default port, add a listener port to the configuration, and cycle the service. The last step of this lab will be to confirm Webmin is accessible on the newly-created port, log into the console, and create a Webmin administrative account.
