Networking - weird adsl problem HK-47 - 25.06.2006, 16:18 Uhr Titel: weird adsl problem
my adsl connection was set up by my isp so that i would need to use a PPPoE dialer. in windows, i use XP's PPPoE dialer and the connection works perfectly.
i'm running kanotix 2005-04 from a live-CD, and it detected my NIC (nForce3 250) perfectly. then i used "my PPPoE config" and it appears to connect succesfully. the KDE network monitors even show up for both eth0 and ppp0. but even after that i still can't access the internet. i haven't even turned on the firewall yet, so that's not likely to be the problem. what do you think could be the problem?
thanks!

After booting off the live cd, go directly to "My PPPoE Conf" from the Kanotix menu; do not configure your NIC first. Once you're done setting up your PPPoE connection, there should be only one device symbol for ppp0.
Otherwise you'll end up with two Internet gateway entries, and Kanotix will attempt connecting via eth0 instead of ppp0.

the thing is, eth0 gets configured automatically at startup even if i don't configure my NIC manually. is there a command to turn the eth0 connectionoff, and can i use PPPoE without it?

i don't really know what all of this means (networking noob), but maybe this will give a clue as to what's wrong?

Do you have a router or a DHCP server in your network that automatically assigns IP addresses to other computers in the network? (This could even be a win machine with internet connection sharing enabled.) If so, try to disconnect it from your LAN before booting off the live cd. Alternatively, unplug the ethernet cable before booting, and reconnect it when you see the KDE screen. (This will prevent eth0 from sending a dhcp request to the router during start up.)
Then complete PPPoE setup and check /etc/resolv.conf for nameserver entries and /etc/network/interfaces for gateway entries.
P.S.: If there is a router in your network, chances are you can also use it as an Internet gateway. Do you have Internet access through eth0 without setting up a PPPoE connection?

it worked! i turned my modem on only when bootup was completed, used the PPPoE dialer, and i finally had internet access. man, i feel stupid for not having tried that before.
