CentOS 5 :: Network 10Mb/s Half Duplex Only. R8168 ?
May 24, 2011
For some reason my network card started going 10Mb/s half duplex instead of 1000Mb/s full duplex. System is connected to 8x1Gb HP switch.Other devices connect fine through the switch and get full 1Gb network.I have Centos 5 with all updates. Driver comes from elrepo and as well is updated.
[root@host ~]# modinfo r8168
filename: /lib/modules/2.6.18-238.9.1.el5/weak-updates/r8168/r8168.ko
version: 8.023.00-NAPI[code].....

I have an Asus P6T7 WS motherboard with 2 embedded NIC's.Relevant output from lspci:
0a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
0b:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
uname -a:
[code].....
I am running a mail server and my POP3 clients have started complaining of slow speeds, about 10 days back. This prompted me to take remedial action on many fronts, finally I decided to look at the link itself.Attempts to force the NIC into full duplex mode using ethtool have failed. The command runs and throws me back to the prompt, but the NIC remains in half duplex mode.
Command that I have tried: ethtool -s eth1 speed 100 duplex full autoneg on modprobe -l r816*:

I have a:
# lspci | grep Ether
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 03)
Looks like the r8169 module that gets loaded is not a valid choice for this chipset. The main error that I see is:
r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
I have verified the cable and it's good the windows machine next door is fine using it without packet loss.
The system is a HP Desktop, just CentOS 5.5 loaded on it (base, with no updates).

I am trying to do an HTTP-based 5.5 install. One thing I noticed: if I press Alt-F4 after specifying the network settings, it says:<6>bnx2: eth0 NIC Copper Link is Up, 100 Mbps half duplex

I had the elrepo kmod-r8168 driver running smooth for a while on my development box.
Yesterday, I did a clean install on it and when I tried to install the latest kmod-r8168 rpm, it failed to enable the networking support:
# yum --enablerepo=elrepo install kmod-r8168
The install performed all proper steps to disable the 8169 driver, I double checked to be sure.This is not a connectivity issue. If I remove the kmod-r8168 rpm, reboot the server and run the ifconfig eth0 up to activate the interface, everything works as expected. I use the latest kernel (2.6.18-194.26.1.el5 x86_64).
First, I performed a clean install, activated the eth0 and did a yum update, then installed the kmod-r8168 with yum. Then, I reinstalled the OS again, activated the eth0 and installed the kmod-r8168 on a 5.5 CD based kernel, same fail results. The only hiccup is: every time I start the box, I have to activate the eth0 interface (with default CentOS 8169 driver):
# ifconfig eth0 192.168.1.3
# ping -c 3 192.168.1.1 (no packets lost)
# ifconfig eth0 up
Once I do this, I have network connectivity.

I just upgraded from 9.04 to 10.04 and so far I have those problems:
1. Before, everything in my system was in English. Now, half is in English, half in another language (PCManFM, some menus etc). I tried setting up Language Support but it changes nothing.
2. Cursor themes work only when hovering the mouse over "X" buttons in the right top corner of the window. As soon as I move the mouse somewhere else, it goes back to default cursor theme, even though I tried selecting 5 different themes - same result.
4. Hibernation don't work anymore. s2disk saves image to disk and then it resumes it but computer stops on text message along the lines of "Resume completed successfully".
5. Changing volume with keyboard shotcuts no longer works.
6. Smplayer does not display picture anymore when playing movies. The view is just empty. I can only hear the soundtrack. It is using XV filter.
7. PCmanFM that used to worked flawlessly, now after going into 1 or 2 subdirectories stops reacting to clicks on file/folder list. Need to open new instance to be able to do anything and this again would become unusable after visiting 1-2 folders.

I'm not sure if this is the right place for this. I'm not sure which veraion of linux I have but it was the latest veraon bfor the recent update. I accidentally hit alt ctrl f11 and my comp went inyo the grub menu. I've tried startx and it does nothing. About half the commands I enter do nothing and the other half r not found or are incorrect. The only vommand thw actualley work is reboot. I searched for this and read a grub guide but it did no good.

I'm clearly missing something small. My Ubuntu machine can see the XP machines in the WORKGROUP, pull files over and even print to the printer attached to one of them. Internet sharing also works. However, the XP machines cannot find the Ubuntu system.

I recently did a clean install of Ubuntu 10.04 on my machine. It previously had windows 7 on it and everything worked flawlessly. Now the gigabit LAN connection only connects at 10Mb/s under Ubuntu. I installed a virtual machine with windows 7 and there it connects at 1Gb/s.

Finally updates are broken - I've been able to use my upgraded F12 system for some time, faithfully keeping up with f10, then f11. Just yesterday it finally broke:
Test Transaction Errors: installing package kernel-2.6.31.12-174.2.22.fc12.i686 needs 10MB on the /boot filesystem
It would appear that the most recent kernel update has broken the 10MB barrier initially set by the version I first installed (for the boot partition). Needless to say, I have quite an investment in this machine, and of course no time to back it all up and do a fresh F12 install. I am hoping someone out there can give me a bulletproof way to steal some space and expand the boot partition...

After compiling the Realtek drivers from their page (ver 8.024), installing the module, blacklisting r8169 and updating the initramfs, I still can't get the network card working.The card is listed in lshw as RTL8111/8168B PCI Express Gigabit Ethernet controller.lsmod shows only r8168.dmesg keeps spitting once and again, every second or so the following:
Code:
[ 1293.452274] r8168: eth0: link up
[ 1294.449785] r8168: eth0: link down

Using ethtool I can set LAN speed and duplex setting.I have Windows PC1 configured at 100MBPS Full Duplex. I have a linux PC configured in auto-negotiation. Windows PC1 can ping linux PC2 using cross over ethernet cable but not using straight cable. Also if I set linux PC2 in 100MBPS Full Duplex mode and Windows PC1 in 100MBPS Full Duplex mode ping is not successful eiether using straight or cross over cable. Is the second PC need to be in auto negotiation mode?

I have a modem that is only compatible with NIC's using 10Mbit Full Duplex. If I have a NIC configured to use 100Mbit Full Duplex, the modem loses connection with the computer frequently.
How do I configure my NIC in Ubuntu to use 10Mbit Full Duplex instead of 100Mbit?

Looking to force eth0 & eth1 to 100MB Full Duplex/Auto Negotiation off but am having trouble.
When I run: "ethtool -s eth1 speed 100 duplex full autoneg off" manually, it works fine. However when I add it to the intefaces file it does not after several different configuration attempts:
/etc/network/interfaces:
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
#auto eth1
#iface eth1 inet dhcp
[Code].....
it seems my current configuration wont allow both eth0 and eth1 to be active at the same time. I would like them to be active-active if possible (if one goes down the other will service all traffice and vise versa).

What it says on the tin really. Whenever i set my sound preferences to 5.1 analog surround i get a sort of high-pitched whine/buzz coming through the speakers along with the regular sound, however if i switch to stereo duplex, it vanishes.

I have installed CentOS 5.3, and updated with yum update. I have kernel 2.6.18-128.1.10.el5xen.
I can't get my wirelss network to work, I have AR928X wireles network adapter.
Do I need to install a newer kernel and install ath9k or can I just downlad a driver without updating the kernel?
I'm new to CetOS and Linux so I hope someone kan give me a step by step guide to what I can do!

I just upgraded from Ubuntu 9.04 64-bit, to CentOS 5.5 64-bit and my RT-73 USB network card doesn't seem to want to function. It always worked fine in Ubuntu by default (plug and play). Is there some setting I need to make to get this working?Even BT-3 (which is quite old) recognizes the RT-73.

I am quite new to this ubuntu business, but i like what I'm seeing so far. Well, almost everything that I'm seeing. I seem to have run into a tricky problem with xubuntu 10.04. I was in the process of customizing my desktop appearance (via Xfce4 Settings manager), and I found a nice theme to go with (dusk I think it was called). I then went on to change the window settings and starting from the bottom most option I browsed the various styles. After a few of these my computer decided to log me out quite suddenly, and I was prompted to login.
This is where the problem is: I type in my password and it logs me in for maybe a half a second only to log me out again. No matter how many times I put in the password I keep getting logged out. So now I'm running xubuntu 10.04 off a pendrive that was used in its initial installation. Is there any way to log back in and stay logged in long enough to undo the window styling at fault? I had put in quite a bit of work migrating files, installing all sorts of things and setting up fancy launchers, and I would prefer not to have to redo it again.
