[ubuntu] Ubuntu server as network connection provider

view story

http://ubuntuforums.org – I run a Dell laptop as a server for some years. I am planning to migrate to a Raspberry Pi. My Dell uses a wireless dongle for network. What I want to know is, is it possible to use the Dell as a network "provider" for the Pi as an interim solution? That is, until I manage to get the WiFi working on the Pi. What I am saying is, is it possible to connect the Dell to the Pi, via a network cable and the Pi to use the Dell's network connection? If it is possible, is there anyone out there that can guide me through the network configuration s please? Thanks in anticipation. (Hardware)
