    Interactive Firewall

    The Mandriva firewall is an interactive firewall, unlike the firewall included with many other Linux distribution’s. Mandriva’s firewall alerts you when someone tries to access blocked services from the Internet or performs a port scan on your computer. If you’d rather not see these alerts, you can disable them in the configuration dialog of the firewall.
