In order to choose the best ISP, you need to know your needs--the speed of the connection you want to use, whether it is a dedicated connection, whether you need IP addresses for your network, and so on. To establish the connection, you need to first set up your modem. Linux supports modems on serial ports by default, so you can verify whether your modem is working properly by using a telecommunication program such as minicom. With the modem up and running, you need to configure PPP. The pppd daemon uses another program, chat, to execute simple connection scripts. The connection script you use should reflect the logon instructions you received from your ISP. To ensure that the PPP connection is activated (and optionally terminated) automatically based on usage, you can utilize the diald daemon. This program monitors IP traffic in the background, and establishes the PPP connection as and when needed, based on the rules stored in its configuration file. You can also use a Linux server in conjunction with an external router. In this case, the Linux server will continue to perform many server functions (such as, mail and name service) while the router will take over IP forwarding and, optionally, firewall gateway functions.
