nixCraft

I installed enterprise linux 5 in my PC. WHen I do ifconfig -a, eth0 is not listed. I manually created ifcfg-eth0, installed Realtec r8168 and added an entry to /etc/modprobe.conf. Still I am not able to see eth0 and not able to connect to Internet from Linux. Whenever I try to start eth0, it says Unknown Device.

It works fine from Windows

Please help me out.

What is the output of lspci? Do you see your pci card listed using lspci?

Your NIC:
r8168 is not correct driver. You need to download and use forcedeth driver for nVidia chipset.

Should I se eth0 after that in ifconfig? Or not appearing eth0 is not a problem here?

Yes, did you loaded correct driver?
Run following after reboot, to verify driver is loaded:

1) Downloaded NFORCE-Linux-x86-1.23.zip driver
2) unzip NFORCE-Linux-x86-1.23.zip
3) cd NV_Linux_DRV_PKG_v1.23/RHEL5/rpm
4) rpm -ivh nvlan-rhel5-0.62-1.23.i686.rpm
rpm -ivh nvsata-rhel5-2.1-1.23.i686.rpm
5) cd NV_Linux_DRV_PKG_v1.23/RHEL5/source
6) created Makefile with the following contents
obj-m := forcedeth.o

But not able to execute "make" to install the driver. Am I missing anything? There is no change even I rebooted the PC.
