NIC not detected !

debianD · 08-08-2009, 12:08 AM

Hi,
I have installed Debian,kernel ver 2.6.26,
My network card is Silan SC92031 PCI fast ethernet adapter, I have done
modprobe sc92031 module and it is loaded also. No problem.
When I do ifconfig, no output.
When I do ifconfig -a it shows two interfaces as
eth0
lo

How would I confirm that my NIC has been detected,making it up is a different deal coz
My ISP uses dhcp server,so may be I need to install a dhcp client,I dont know how to do it,what is the module name for that?
Please guide!

Cheers!!

It shows eth0 is detected on your machine. if you want to configure DHCP refer the following link

How does your computer connect to your ISP? If via the NIC, normally there is a device in between your NIC and the ISP; that device has LAN port(s) and a WAN port going to the ISP. That device normally does the DHCP with your ISP (and a lot of other very useful things) leaving you free to configure the LAN how you like. It is normally possible to configure the device to be transparent so your computer can get its IP address from your ISP but that is only necessary in unusual circumstances and requires strong security on your computer.

yes via NIC, can you please name the device or at least what it is called theoretically?
For any connection don't need to configure my LAN.Once the dhcp client is installed everything rest is done automatically.

Modem and/or router are typical names for the device

It looks like your NIC is detected.
You can probably get connected with this command (run it as root)
dhclient eth0
If that works, then all you need to do is set up your /etc/network/interfaces file like this

Code:

tred@vaio:~$ cat /etc/network/interfaces
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

tred@vaio:~$

and your eth0 will be brought up when your machine boots
