Run this:

# /sbin/modinfo -F filename r8168
/lib/modules/.../kernel/drivers/net/r8168.ko

If you do not get the above response, your module is not installed properly. If you get the response, run this:

# /sbin/modprobe -r r8169
# /sbin/modprobe r8168

Then, reboot the server.

I reformatted USB drive to FAT32, and reinstalled, and thought “check with fdisk -l to ensure device mount”, and lo and behold I WAS USING THE WRONG device… so FAT32 mounted fine, and I RPM’ed the file, rebooted, and … still no ethernet. bummer.

I did an lspci and the RTL8111/8168B controller is loaded and running, so I guess something else is going on.

oh well. Im not sure what step I take next (aside from getting another machine, which I would like to avoid), but I do very much appreciate all your help. I learned alot.

thanks again

Just use an USB thumb, it costs $10.00.
CentOS will automatically detect the flash drive, because it is formatted in FAT32. You can also use the fat32format utility to quickly/properly format an NTFS drive to FAT32. I fixed some USB thumbs with it, works very well.

Hey Floren;

Thanks again for the help.

I guess I back to where I started. Without a network connection, the only way to load new software is via USB drive, or CD/DVD. Without NTFS support, USB Flash is out for the moment.

Any idea what I need to do to mount either a CD-R or DVD+R created on a windows box so it will mount properly on CentOS 5?

You will need a custom kernel, for NTFS. It is available into centosplus repo, so you do not have to compile anything. Once you have the right kernel updated, follow the NTFS mounting instructions. Please note that the NTFS module is not enabled in the centoplus kernel starting with CentOS 5.3. This is because NTFS in 5.3 is broken. See the bug info, for more details.

Hey Floren;

Thanks for that. One last issue hopefully you have some thoughts on: how do I mount an NTFS USB drive on CentOS?

I tried doing

“mount /dev/sdb/ /mnt/sda1 -t NTFS”

but it complains:

mount: unknown filesystem type ‘ntfs’

First, make sure you install the proper RPM version.
Check what kernel you have installed:

yum list kernel*

After you install the RPM, run:

/sbin/modprobe -r r8169
/sbin/modprobe r8168

Then, reboot the server. Let me know the results.

An USB flash drive will do the trick, just copy the file to a local directory. You will also need to have installed the RPM package, latest is 4.4.2-48.el5 version.

$ cp /media/disk/kmod-r8168-8.010.00_NAPI-1.el5.x86_64.rpm /home/floren/tmp
$ su -
# rpm -ivh /home/floren/tmp/kmod-r8168-8.010.00_NAPI-1.el5.x86_64.rpm
