Step by Step, installing webmin.

Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.

Webmin is available in the repositories, but the steps below will assure you the latest & greatest version.

I’d not be surprised if many people did not know such a thing exists.  As always use all caution, read up on all commands before you do them.  Webadmin is available in the repositories, but this will assure you the latest & greatest version.
