DSL Connecting Problem, debian

r_sreekumar · 05-02-2009, 10:42 PM

Hello,
I have recently installed Debian (Lenny) in my machine. I configured my dsl broadband connection with pppoeconf. Everything went fine. I could login with
"pon desl-provider" . Now the system is getting proper IP address and DNS from the provider. ( I checked with "ifconfig"). But unable browse or ping to any external site. When I tried with "Etch" also, this problem was there. But I have absolutely no problem in using the same connection from "SUSE"(My default OS, from which I am posting this!!!), "FC" or "Windows". Please help.

Have you a '/etc/resolv.conf' file where the DNS adresses are written ?
If the resolv.conf file is placed elsewhere, try to make a soft link to it :

cd /etc
ln -s <path to the resolv.conf file>

You can also write the provided DNS addresses into /etc/resolv.conf file from the connexion script, or using the ip-up script.
My ip-up script is like that :

Code:

#!/bin/sh
#
# This script is run by pppd when there's a successful ppp connection.
#
cp /etc/ppp/resolv.conf /etc
