Hi Tom
The answer is no, that file is in you Linux image, you can find it in /etc/network/interfaces . One way to do this is to use vi (a text editor). If you use vi the procedure would look like this, type the following commands:
cd ../../etc/network
vi interfaces
Then click i to start edit mode and make the changes Kenny suggested, then when you are finished hit the esc button to exit edit mode and type :wq! To save the changes
I hope this helps you.
