when i enter the command sudo pppoeconf, it shows like this:
I found 1 ethernet device:
eth0
Are all your ethernet interfaces listed above? (If No, modconf will be started so you can load the card drivers manually).

when i say yes then it starts detecting and then:

Sorry, I scanned 1 interface, but the Access
Concentrator of your provider did not respond. Please
check your network and modem cables. Another reason
for the scan failure may also be another running pppoe process which controls the modem.

i have a d-link glb 802c modem and the problem is that i cant connect in windows..(dual shock)..i use ubuntu 8.04…..and all my modem cables are connected and the adsl light is stable…..and my laptop(ubuntu 8.04)shows the same error..
