How to Configure Webmin Modules

Webmin serves as a powerful tool for managing Unix-based systems from an intuitive web interface. With its modular architecture, it offers functionalities that allow administrators to handle operations such as user management, service monitoring, and server configuration efficiently. In this guide, we will walk through configuring specific Webmin modules to harness its full potential.

Prerequisites

• A server with Webmin installed. Refer to this guide for installation instructions (Official site).
• Basic knowledge of Linux command-line operations.
• Admin access to the Webmin panel.

Step-by-Step Configuration

Accessing Webmin

Begin by logging into the Webmin interface. Point your browser to https://your-server-ip:10000 and enter your credentials.

Understanding Webmin Modules

Webmin’s structure is organized into modules, each handling specific functionalities. Popular modules include:
