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 you can also create backups for the system and restore.
The installation is simple, you have just to download the Debian package from the webmin page (actual package is 1.530) and install it via the command:
dpkg -i webmin_1.530_all.deb
After the package is installed, open your browser and enter https://ip:10000 (port 10000 with ssl certification) then login with your root acces .
