if you want to enter a c line in to your box as your thread title mentions ,you willneed to connect your box to your router using a crossover cable and connect your computer to your router using an ethernet cable . you will need to download dream control center (you use this to access cccam in your dreambox)you then put your c line in there. also download cccam config creator ,it makes things a little easier to set up. you might get dream control center by clicking on the link in my signature area and choosing dreambox.you will have to use google for the other file. by the way you have a thread opened all ready so maybe its better if you post all your questions in there , other people reading would learn easier if its all in the one thread .
