Getting online / How to configure the network with Ceni
Ceni is not a service. It is a configuration application that exists when configured, therefore does not use system resources as such.
Many wifi cards are deemed as non-free in Debian and cannot be shipped on an aptosid-iso*. You will most likely need non-free firmware to be available on a USB-stick to install within the operating system. Please refer to non-free firmware debs on a stick.
If you have a DHCP server in your LAN and your computer is connected to it while booting up your network-settings should be configured automatically - otherwise you need to start Ceni Click Kmenu>Internet>Ceni. This will open a terminal/konsole whereupon it will ask you for your root password, ( on a live-Cd there is no password set).
The fast way to access Ceni is to open the terminal/konsole and type
ceni
whereupon it will ask you for your root password.
One of the Ceni strengths is its ability to configure WiFi wireless cards on the fly, an alternative is here:
