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).

Connecting with a 56k Dial-up Modem
KDE has a front end for dial up modems called KPPP Internet Dial-up Tool, found in the main menu under Internet.

ferm is a terminal tool to maintain complex firewalls, without having the trouble to rewrite the complex rules over and over again. ferm allows the entire firewall rule set to be stored in a separate file, and to be loaded with one command. The firewall configuration resembles structured programming-like language, which can contain levels and lists.
apt-get install ferm
ferm manual :: Please note that ferm will not teach you how a firewall works nor how to write good rules.
There is a GUI solution in the form of gufw which based on the backend application of ufw.
