Webmin is a web-based server management control panel for Unix-like systems. Webmin allows the user to configure operating system internals, such as users, disk quotas, services or configuration files, as well as modify and control open-source apps, such as BIND, Apache HTTP Server, PHP or MySQL.
Webmin is largely based on Perl, running as its own process and web server. It defaults to TCP port 10000 for communicating, and can be configured to use SSL if OpenSSL is installed with additional required Perl Modules. Webmin is built around over 110 standard modules, which have an interface to the configuration files and the Webmin server, which makes it simple to add new functionality. Due to Webmin's modular design, it is possible for anyone who is interested to write plugins for desktop configuration. Webmin allows for controlling many machines through a single interface, or seamless login on other Webmin hosts on the same subnet or LAN.
Webmin is primarily coded by Australian Jamie Cameron and released under the BSD license.
If a plugin for certain tasks is not available, it is possible to open a terminal and perform various task through a command line interface (CLI). This is especially useful if using SSH (or similar) is not an option.
While Webmin was included in the official repositories of some Linux distributions (Debian and Ubuntu) it was removed from those because Webmin was not compatible with the way that the distributions' packages handled configuration files and caused unexpected issues with systems.
Webmin can be expanded by installing modules, which can be custom made. Aside from this, there are two other major projects that extend the functionality of Webmin:
Webmin released Minecraft Server Module 1.0 in January 2013, and version 1.1 in March 2013. The module presents a very basic GUI for server administration. The Webmin Minecraft server is free and open source with no limitations on simultaneous players.
