NIC detection problem
 

Hi,
I have just installed RedHat enterprise Linux 5 on an intel core 2 Dou Machine with Windows XP already installed on it problem is that my NIC is not getting dtected by RedHat whereas its working fine with windows i have tried the following but still stuck with the problem

Disabled the on board LAN option

#lspci | grep -i ehternet
it shows " ethernet controller: Realtek semiconductor co: RTL8111/8168B PCI Express gigabit Ethernet controller (rev 01) "
#modprobe 8139too
# cat /etc/modprobe.conf
it shows "alisas eth0" no other interface

also tried to manually add it using system-config-network

Kernel release is 2.6.18-8.el5, also when i issue ifconfig -a command it shows an interface "sit0" dont know abt that. Any help will be highy appreciated.

The 8139too driver is not the correct for either in Windows or Linux;

See: http://wiki.centos.org/HardwareList/RealTekRTL8111b

well I got the driver from the link, tried to install it according to the readme file but on the very first command i got the following error

[root@localhost r8168-8.003.00]# make clean modules
make -C src/ clean
make[1]: Entering directory `/installations/r8168-8.003.00/src'

make[1]: *** [modules] Error 2

Now what should I do?

Install the kernel-devel and kernel-headers packages; yum install kernel-headers kernel-devel

Hi Lenard,
main problem is that there is no internet connectivity available as there is no NIC so yum is unable to do any thing. any alternative?

Check the installation media, from where the rpm packages are type;

rpm -Uvh kernel-headers*.rpm kernel-devel*.rpm [and maybe kernel-xen-devel*.rpm]

If you have the kernel-xen package installed then you also need the kernel-xen-devel package.

To find out first type: rpm -qa 'kernel*'
