How to Get a DSL Modem to Work on Ubuntu Linux

DSL modems take special configuration in Ubuntu Linux.

Using a DSL modem on Ubuntu Linux follows a different process than standard Ethernet configuration. If you are not using a router and instead are connecting to the DSL modem through Ubuntu, it will need to know your login information in order to connect you to your ISP and make sense of the information sent to your computer. Although there is no graphical DSL configuration tool for Ubuntu, you can configure your DSL modem through the system terminal.

Things You'll Need

• Root Ubuntu password

Instructions

1. Log in to your Ubuntu desktop.

2. Connect your Ethernet card to the DSL modem with an Ethernet cable.

3. Access the system terminal by opening the "Applications" menu, followed by "Accessories," then clicking "Terminal."

4. Type the command "sudo pppoeconf" without quotes into the terminal. You will be asked to supply the root password.

5. Click "Yes" to confirm your DSL modem connection.

6. Enter your username and password when prompted.

7. Choose "Yes" to all options when presented. Upon confirming the last option, the program will exit and your DSL link will be established. You have now configured your DSL modem.

Tips & Warnings

• You can shut off your DSL connection at will from the command prompt by entering the command "sudo poff dsl-provider" without quotes.
