Device driver for eth0, CentOS

**parthanayani** · 01-27-2008

Hello forum,
I am new to CentOS. I recently installed CentOS version 5 on a new gigabyte mother board having a built-in ethernet controller from Realtek RTL 8110SC . When I tried to installed the driver, I could not find this device listed in the drop down list of drivers available in CentOS. I downloaded a driver for Linux from Realtek site but have no clue on how to:

1. Make this driver appear in the drop down list of available drivers.
2. Install this driver, as the folder contains some makefiles, .C and .H files.

Any immediate help will be greatly appreciated. Thank you.

Hi parthanayani and Welcome!

The first step to get this working is to identify the chipset it uses. Boot CentOS and open a terminal/konsole window, login as root and issue these commands, and then post the output back here for more help.

Code:

lspci

Code:

ifconfig

Code:

lsmod

Hello Mike Tbob,
Thanks for the reply. I am pasting the output of the three commands mentioned in your reply.

02:0f.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8110SC/8169SC Gigabit Ethernet (rev 10)
Subsystem: Giga-byte Technology Unknown device e000
Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 10
I/O ports at d800 [size=256]
Memory at fddfe000 (32-bit, non-prefetchable) [size=256]
[virtual] Expansion ROM at fdc00000 [disabled] [size=128K]
Capabilities: [dc] Power Management version 2

I selected e000 as the device when I tried to install the driver for this card and I think it is because of this the above "unknown device" error has come

I hope to get an early solution. I am also curious to know how the drop down list is created? Is it possible to add devices to this list? Thanks in advance.

**MikeTbob** · 01-29-2008

Ok, it seems this is a problematic card from the search I've done, but I think it might work anyways. Check to see if this module is already builtin to CentOS
Post any errors that you get please.

Code:

modprobe r8169

Which Driver did you download?
r8169-6.004.00.tar.bz2?? Is that what you have?

whatever you have, lets say the file is in your home directory, you need to "cd" to that directory

Code:

cd /home/parthanayani

Code:

tar -jxvf r8169-6.004.00.tar.bz2

This will create a directory like

Code:

r8169-6.004.00

Change to that directory

Code:

cd r8169-6.004.00

Now view the README

Code:

nano README

The README, should explain the rest, but if you still need help, don't hesitate to ask.

I am also curious to know how the drop down list is created? Is it possible to add devices to this list?

It's created automagically, I don't think editing the drop down would help yet.

**parthanayani** · 01-30-2008

Hello Mike Tbob,

As advised I followed unpacked the tar file and followed the readme file and was able to install the driver

. I had to re boot the system to see the driver. Now I see two drivers

for eth0 and not sure which one to activate. I tried activating them but I am getting an error. Perhaps there is a problem with my connection (using netgear router) so selected DHCP. Any suggestions please? Thank you.

**MikeTbob** · 01-30-2008

What exactly do you mean, you see two drivers? What command are you using?
Did you modprobe r8169?
Any errors?

**parthanayani** · 01-31-2008

Hello Mike Tbob,

1. I did a modprobe r8169 and there were no errors reported.

2. When I opened the network configuration window, I saw

Under devices tab

Profile Status Device Nickname Type
ticked Inactive eth0 eth0 Ethernet

Under the hardware tab

Description Type Device Status
Realtek Semiconductor Ethernet peth0 OK
r1000 Ethernet eth0 Configured

The system is connected to internet through Netgear router and the router allots the IP address, therefore I enabled DHCP, but I am getting errors. Even at boot time, the message "Determining IP address for eth0" appears and after some time FAILED appears.

I am able to connect to the internet through Windows so I guess HW is OK.

What is this peth0? I am scared of deleting one of these entries as I do not know how to get it back. The entry shows /dev/eth0 but when I checked the folder, I could not find eth0. Hope you will be able to help me

from the info I provided. Thank you.

Partha

**MikeTbob** · 02-01-2008

Ok, try this. After you modprobe r8169. issue this command and post the output.

Code:

dmesg

Also post the output of this command

Code:

ifconfig

Try using the command line as root, and use this command after modprobe

Code:

dhcp eth0

**parthanayani** · 02-03-2008

Hello Mike Tbob,

The system has become very very slow. Logging in takes several minutes so also any commands. For example if I right click on desktop and try to open terminal, it takes more than 5 minutes to open the terminal window. Could this be because of network driver? Could it be virus?

1. When I try dhcp eth0, I get error bash: dhcp: command not found.

2. Below is the output from the two commands.

It's hard to say why your system slowed down, did it slow down immediately after modprobing 8169 you could try removing the modules and see if that helps.
rmmod r8169
I did see some messages in dmesg that might need more investigating:

8250_pci: Unknown symbol serial8250_unregister_port
8250_pci: Unknown symbol serial8250_resume_port
8250_pci: Unknown symbol serial8250_register_port
8250_pci: Unknown symbol serial8250_suspend_port

Is this your Video or Sound card?
From the output of ifconfig, it looks like you have an IP address already. Try pinging google

Code:

ping -c5 google.com

Also try dhcpd eth0 instead of dhcp eth0
