Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely. See the standard modules page for a list of all the functions built into Webmin.

Webmin suppports Ubuntu, but FBSD, RedHat, and Solaris are most supported. It's been a while since I've used WebMin but it seemed easy-to-use but solid and powerful last time I tried it out.
