Connecting to the Internet

Knoppix is a child of the Internet. Knoppix does networking with its eyes closed. The main ways to get connected to the Internet are:

Knoppix is designed first and foremost for wired Ethernet networking. This gives you the best chance of success. Meanwhile, the following connection methods are not so easy with Knoppix:

The above methods tend to rely on proprietary software that only works on Windows. Even if the proprietary software were available for Linux (which it sometimes is these days) it cannot be distributed with Knoppix due to licence constraints.


A broadband Internet connection lets you download at up to ten times the speed of a conventional modem. It also lets you use a telephone handset on the same line at the same time. The technical name for broadband in the UK is “Asynchronous Digital Subscriber Line”, or ADSL. To use broadband Internet with Knoppix, you need:

To make the connection:

  1. Make sure the Ethernet cable from the router/modem/gateway is connected to the computer's Ethernet adapter.

  2. Start Knoppix.

  3. During the startup process, Knoppix will automatically detect the network card. Knoppix will obtain an IP address automatically from the ADSL router/modem/gateway.

  4. If you have not already done so, use a web browser to visit the ADSL router/modem/gateway's configuration page. To learn about the web browsers included in Knoppix, see the later section, "Browsing the World Wide Web". Enter the necessary information on the configuration page to make the connection to your broadband Internet Service Provider (ISP).

  5. You're done! As long as the 'upstream' connection to the Internet is working, you will be connected to the Internet.


Dial-up Internet is the older, slower way to access the Internet. To connect this way, you need an account with any standard Internet Service Provider (not AOL) and one of the following:

There are two main ways to make a dial-up connection. The recommended way is to use “K Point to Point Protocol” (KPPP). The alternative, in case KPPP doesn't work, is the “Worldvisions Dialer” (WVDial).

Connecting using KPPP

  1. Click the Knoppix menu in the lower left corner.

  2. Point to Network/Internet.

  3. Click "Modem Dialer"

  4. The "KDE Point-To-Point Protocol (KPPP)" program will start.

  5. Click "Setup".

  6. Click the "Device" tab.

  7. If your modem is plugged into the serial port called "COM1" in Windows, set "Modem device" to "/dev/ttyS0". If it is plugged into the port called "COM2" in Windows, select "/dev/ttyS1". If you have a PCMCIA Cardbus modem, select "/dev/modem". If you have an internal ISA modem, select "/dev/ttyS0" first; if that doesn't work, try "/dev/ttyS1", "/dev/ttyS2" or "/dev/ttyS3".

  8. Click the "Modem" tab.

  9. Click "Query modem".

  10. You should see a response from the modem. If not, go back to step 7 and try another "modem device" setting.

  11. Click the "Accounts" tab.

  12. Click "New".

  13. Click "Dialog setup".

  14. In "Connection name" enter a name for the connection eg "test".

  15. Beside "Phone number, click "Add".

  16. Enter your Internet Service Provider's dial-up access number. If you don't know, ask your Internet Service Provider. Click OK.

  17. Click OK. This will take you back to the accounts screen.

  18. Click OK again.

  19. Enter your login ID and password. Again, if you don't know what they are, ask your Internet Service Provider.

  20. Click Connect.

  21. You should hear the modem work.

  22. In a few moments, the KPPP window should shrink down to the Taskbar. It should then read "00:00" on the Taskbar. This indicates your time online in hours and minutes. Congratulations, you are connected to the Internet.

  23. To disconnect, click the KPPP button in the Taskbar.

  24. The KPPP window will come back up.

  25. Click Disconnect.

  26. The phone call will be ended.

Quick help

Question: It says “The PPP daemon died unexpectedly!”

Answer: Check your username and password.

Question: KPPP just doesn't work.

Answer: Sorry, it seems that KPPP doesn't work with all ISPs. Luckily, there is an alternative. The “Worldvisions Dialer”, or “wvdial” is included with Knoppix. For an example of how to use wvdial, see:
