Now, I know that there are other web-based admin tools out there, but most of them aren't free. There are also commandline tools that do the job just fine, for example, MSM - Minecraft Server Manager, but there are some of us who prefer to use a GUI instead of a console.
So, let's get this started.
Downloading the server + module:
Download the archive from the Webmin official site/through Webmin itself.
Then download the minecraft server:
The view of the control panel, quite nice:
The configuration screen is simple and intuitive.
The module also features a realtime console as well as some other tools for player/world administration.
The only downside is that the module allows for only one server to run at once as far as I know, and the other thing about this is that because this software is new, there are some bugs that I've already noticed.
Since this is my first post here, please don't be too harsh on me
