Virtualmin

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. Usermin also provides web interfaces for viewing and managing data in MySQL and PostgreSQL databases, editing Apache .htaccess configuration files, and running commands on the server. The administrator has full control over which of these modules are available to users.
