Quick install guide

These are the drivers for the RTL8111B/RTL8168B/RTL8111/RTL8168/RTL8111C chipset as provided by Realtek
Please do NOT use them for other chipsets or if your distribution includes a suitable driver

1. Read (and follow ) this tutorial in order to add the RPMForge (also known as Dag ) repository to your list. To cut a long story short:
a) Download the rpmforge-release package. Choose one of the two links below, depending on your architecture. If you are unsure of which one to use you can check your architecture using the command uname -i (executed at a bash prompt).
   for i386: http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
   for x86_64: http://apt.sw.be/redhat/el5/en/x86_64/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
b) Install Dag's GPG key
   rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
Verify the package you have downloaded:
   rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm
Security warning: The rpmforge-release package imports GPG keys into your RPM database. As long as you have verified the package and trust Dag then it should be safe.
c) Install the package:
   rpm -ivh rpmforge-release-0.3.6-1.el5.rf.*.rpm
d) Install the dkms enabled R8168 driver package from rpmforge (and any needed dependencies):
   yum install --enablerepo=rpmforge dkms-r8168
Warning: a newer version of the drivers is available from here. However, you will have to do a manual install, i.e. download it locally and then use
   yum localinstall dkms-r8168-8.009.00-1.noarch.rpm     Note: you will still need some packages from rpmforge and from the distribution itself
2. That's all !

Now go to step 1 and do read the instructions available in the wiki (yes, I know you skipped them!)
