Connecting to the network

There are a few ways for Knoppix to connect to the internet. You can view these options by clicking the ``K'' icon at the lower left corner, then select ``Internet''. Figure 5 shows you the choices.

• Default: by default, Knoppix detects any ethernet network card that is installed, and attempt to connect to a network using DHCP (dynamic host configuration protocol). This handles most, if not all, of the cases for office computers. There is nothing that you need to do in this case. This default also works well for most home computers that are connected to a router or firewall device.
• ADSL/PPPOE configuration: this is suitable if you have a cable modem or DSL modem connected directly to a NIC (network interface card) on the computer. PPPOE (point-to-point protocol over ethernet) is a common protocol used by DSL and cable modems. You will need your username and password to make the connection.
• KPPP: this is suitable if you have a modem on the computer, and wish to use it to connect to the internet. Unfortunately, Linux has relatively sparse support for WinModems (modems that use the main processor to modulate and demodulate signals). You will need your username, password and access phone number to use this feature.
