What is Webmin?

Before getting into our guide, let’s take a look at what Webmin is and how it works? Webmin is a Perl-based system that runs its process and servers. The software is a web-based UI for system administration designed to work with Unix or Linux-based operating systems. For example, you can use Webmin in your LAN or MAN network, where Webmin lets you manage and communicate with all of your servers from one PC. The system also allows you to control multiple servers from each interface. You will need to install the Webmin client on your servers and access the control panel in your main system PC through any modern web browser. 

How to Access Webmin?

You can access your Webmin dashboard from any modern web browser. You can connect and control your servers through the dashboard, but make sure the client Webmin is installed on your server. There’re many ways of configuring your servers for logging in, but we highly recommend using SSL configuration to have a secure login in your servers. However, you can also use the TCP port for better security.

Things to Consider Before Installing Webmin on your Ubuntu
