and is accessible through a web browser.  Its purpose is 

A handy tool for those who would prefer to do their admininstration via a web-based GUI rather than the command line or directly at the console. Find it in /usr/ports/sysutils/webmin. Once you install it, you'll have to configure it by running the setup.sh script that it uses to set itself up. Note that the program depends on perl and the latest version in ports may not be the latest version of the program proper (there's an option w/in the program itself to install or update to the latest version).
