I did a clean install of Debian Squeeze on my new laptop using the net install CD image. I'm having an ADSL broadband connection and during the installation I used the ppp-udeb module to configure the internet and I was able to download the required packages from the Debian mirror. But after the completion of the install process and reboot, I'm not able to connect to the internet. I get a message saying "unknown host" when I PING to http://www.google.com. But I could see from the logs that the network has been established. I don't have much knowledge of networking. I did try some troubleshooting but to no avail. Below is the log of the steps I did for troubleshooting. I'm stuck at this point. Kindly help me to connect to the internet from my Debian box.
