Teacher Overview 

Raspbian is a Debian-based computer operating system for the Raspberry Pi computer. There are several versions of Raspbian including: Raspbian Stretch and Raspbian Jessie. Raspbian was created by Mike Thompson and Peter Green as an independent project, with an initial build completed in June 2012. Since 2015, Raspbian has been officially provided by the Raspberry Pi Foundation as its primary operating system for the family of Raspberry Pi single-board computers and is highly optimized for the Raspberry Pi line's low-performance ARM CPUs. 

The internet of things, or IoT, is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers (UIDs) and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. 

IoT devices could be a person with a heart monitor implant, a farm animal with a biochip transponder, an automobile that has built-in sensors to alert the driver when tire pressure is low or any other natural or man-made object that can be assigned an IP address and is able to transfer data over a network. Increasingly, organisations in a variety of industries are using IoT to operate more efficiently, better understand customers to deliver enhanced customer service, improve decision-making and increase the value of the business. 

In this project you will go through all the steps to set up the Webmin software package for the Raspbian operating system. Webmin is an excellent capability  if you wish to have a web-based interface for system administration. It removes the need to manually edit configuration files and makes administration significantly easier. You can easily setup, modify and control applications such as an Apache HTTP server, SQL, Postfix, DHCP, PHP and many other software packages. These require a bit of setting up so check out the Webmin wiki page once you have it installed. There are modules that you can use to extend the functionality of Webmin. For example, Virtualmin is a module that manages multiple virtual hosts through a single interface.  

This project will allow you to configure Webmin to send emails from an email account to another from the interface without having to go to the account to login. This can be used to send emails automatically by Webmin to alert you to when there is a scheduled backup or when background monitoring is performed.

Conclusion

This project is designed to introduce you to a system admin interface and the applications it has within IoT. You will have run multiple commands that will configure the Raspberry Pi to be able to set up a local host browser on port 10000 which will have a system admin interface running on it. Next you configured Webmin to send an email from your email account to another remotely. Webmin is an extremely powerful application and has many different tools, and this project is just scratching the surface of what you can achieve with it, there are so many different projects you can build around this.
