eth0 interface problem


I own a Compaq Presario V6211AU notebook pc, I have nvidia nForce networking controller as my ethernet controller. I have installed Mandriva 2007 spring edition.

Every time linux boots, it says eth0: interface doesnot seem to be present. Delaying initialisation, then creates a new interface eth(old + 1) eg. eth1 . As a result I am not able to connect to the network or the internet.

I connect to the internet through a proxy server and I have statically assigned IPs.

I have tried Mandriva 2008 also, still the same problem persists. Please help me.

Do you got the nForce Drivers for you Motherboard installed?
Now nVidia no longer provides new nvnet drivers in favor of open source alternatives. More info at
http://www.nvidia.com/object/linux_nforce_1.11.html
Module forcedeth is automatically loaded instead.

Well, I have the same problem and lsmod tells me that forcedeth is indeed loaded. But the dhcp client still does not get a reply.

Do you suggest to install the precompiled driver from nvidea instead of the one provided by the distro (opensuse 10.3 in my case)?

@lauer - you should give it of course I try.
For example the livna repos regarding the nvidia-kmod, this are nice drivers for my video card no problem
but if I start a benchmark with the once direct from nvidia then I see that the ones from nvidia do a much better job.

So check the once from nvidia for your network / and motherboard.

regards.

Thanks for the reply. I will give it a go when I'm back at my machine - probably friday - and report the results.

Thanks for your suggestion. I tried that but the problem still persists. I feel that mac address (assosciated with a particular eth? interface) changes on boot. For eg. On booting when the mac address gets queried, 0 is returned and therefore a new eth interface is created and a new mac address is assigned then. Don't know what to do. I badly need a solution to this problem.

Aren't there no README or INSTALL or FAQs documents within the driver from nvidia?
Maybe the /etc/sysconfig/networking-scripts/ifcfg-eth0 needs to be checked?
Onboot = yes and so on ?

Ha! I've got it (I'm actually posting from my linux box)

After some google sessions, I've found the solution in an Ubuntu forum. The forcedeth network driver of my chipset (nforce 680i) is missing some options under opensuse 10.3. Adding

Code:
options forcedeth msi=0 msix=0
to

Code:
/etc/modprobe.conf.local
solved my problem.

Everything else (updating with the forcedeth package from nvidia, tinkering with the BIOS) did absolutely nothing.

@vishwaspbhat: my MAC adress was stable. So you might be having a different problem than mine. Sorry.
