The first thing you'll need to do is get Point-to-Point Protocol (PPP) up and running. You'll also want to configure diald so that your Linux router will dial up your ISP whenever a connected machine needs to get out. Configuring diald and the modem are really beyond the scope of this chapter, I'm afraid. Instead, you'll have to head over to the Diald HOWTO, available at http://www. ibiblio .org/pub/Linux/docs/HOWTO/Diald-HOWTO .
