I'm pretty new to linux, so pardon my new-bee-ness.

I downloaded a version of KNOPPIX, and everything works great- except for my Charter cable internet access. I'm using a standard Intel 10/100 E-net card, which is detected by knoppix. The card connects to my cable modem, which I don't know much about b/c I got it from Charter, and they won't tell me anything about it (I've contacted tech support about this multiple times: they "don't support linux)." I can even connect to my Belkin router by typing in it's IP address. I just can't go to any web addresses.

I've tried the netcardconfig command both on the KDE desktop, and in the console. The DHCP broadcast gives me the error: "eth0 NIC link is up 100mbps, full duplex- OPERATION FAILED." If I try to configure the card w/o DHCP, but I don't know what I'm doing (i.e., what values to enter for DNS and Default Gateway), and it doesn't work anyway. When I type the command ifconfig -a, i get this:

etho Link encap:Ethernet HWaddr 04:AC:6E:20:7C

Also, when I typed in the route -n command, I got a bunch of empty fields, with no values- Destination, Gateway, Genmask- all blank fields. When I type in the 127.0.0.1 address that I recieve from ifconfig -a into a browser, I get an error message- something like "permission denied" or "not allowed." I've tried routing the cable modem through USB interface instead of ethernet, but that doesn't work either. Any suggestions??

i'll try to help. I am running KNOPPIX 3.7 on my dell inspiron 4100 laptop. It detected my nic fine. When the desktop came up, i clicked on the penguin icon on the panel at the bottom of my screen, right next to the KDE "start" button. Then i go to Network/Internet --> network card configuration.

then a box popped up asking if i wanted to use DHCP. i said yes. that's how i configured my card. My router, i made sure, was setup to use dhcp, and assign ip addresses. What router are you using?

Running Knoppix with PCMCIA cable adapter.

I noticed your broadcast is for eth0. On my computer, the internet card is eth1, not eth0.

Since Knoppix handled everything with those settings I'm not sure how to change that, but that might be a place to start looking.

i'm using a belkin 802.11b, however, i should note that i only connected it ONCE: i didn't have it previously connected when i got my comp hooked up to cable on xp. i hooked it up today to see if my E-net card would recognize it, and it certainly did. i'll try to use the router some more, to see if i can get it to connect to the modem, v.s. trying to do it w/ just the E-net card connected directly to the modem. however, in theory, i really shouldn't have to do that.... :-/

also, i tried the dhcp option, and mine gave me an error message (can't remember exactly what it was, but it hung for awhile).
