How do I create a eth0 interface?

DodoTux · 08-25-2006, 01:42 PM

Hi

I know it sound weird, but i mean it. By doing "ifconfig" i only had a "sit0" IPv6overIPv4-Tunnel which didnt allow me to connect to the LAN at school nor at home (both over DHCP). I know that i used to have a normal eth0 in a previous Debian install. Now, how do i "make" that eth0-Interface? i searched, but didnt find.

Thank you!

what is the output of dmesg? It sounds like your install failed to detect your network card. You can try as root running /etc/init.d/networking restart or ifup eth0...

DodoTux · 08-25-2006, 02:09 PM

Ok,

ifup eth0 outputted the following: "Ignoring unknown interface eth0=eth0"

and /etc/init.d/networking restart: "Reconfiguring network interfaces...ifup: interface lo already configured
done

dont really know how to continue? cant i make the eth0 myself?

As I said, it sounds like the kernel didn't find your ethernet card at boot time. What is the output of dmesg? What is the output of lspci (that's lowercase LSPCI)?

Here is the output of dmesg:

and lspci also lists my EthernetCard as an EthernetController: Digital Equipment Corporatoim DECchip 21142/43

pljvaldez · 08-28-2006, 01:25 PM

Well, it looks like the system never loaded the ethernet controller. From googling around, it appears that the DECchip should be controlled by the "tulip" driver. Try insmod tulip.o as root. If that doesn't work, you might need to go find the right module on your hard drive. It should be in something like /lib/modules/2.6.8-3-686/kernel/drivers/net. It might be called tulip.ko instead...

After it's loaded, you should be able to do /etc/init.d/networking restart.
