In this article, we will be looking at how to install the Debian GUI called Webmin on your system.

What is Webmin

Webmin is an open source web based interface for system administration that uses the LSB (Linux Standard Base) as its underlying basis. The LSB is a specification specifying how Unix like operating systems should be organized and structured. With Webmin, you can configure and administer your server or other GNU/Linux machine from any browser. 

It combines common UNIX utilities into one easy to use package that can be installed on any version of Linux or Unix.

Webmin offers a flexible and powerful way to administer your server. It provides features like user management, file sharing, remote access, and configuration management tools. It provides easy access to many common services like DNS, SMTP, FTP, iptables and NFS

In addition to these basic features, Webmin offers many other helpful tools that can help you manage your servers more efficiently.

Webmin also comes with some preinstalled modules, including LAMP (Linux, Apache, MySQL and PHP) and LEMP (Linux, Nginx, MySQL and PHP). The software also features a complete database management toolset written in Perl and PHP.

In other words, it simplifies the administration and configuration of services on your local network and provides the user interface for doing so.
