CentOS 5 Networking :: Reboots Causes Unpredictable Enumeration Of Ethernet Drivers Causes Eth0 To Be Random?

Mar 20, 2009

I have several systems experiencing this issue, but the "worst case" system at the moment is a system where there are 2 dual-port PCI-X e1000 cards, and two on-board e1000e PCI-express card.What happens is maddening. If the /etc/sysconfig/hwconf is removed, and kudzu is not run, and the 6 interfaces each have a corresponding script:

/etc/sysconfig/network-script/ifcfg-eth0
/etc/sysconfig/network-script/ifcfg-eth1
/etc/sysconfig/network-script/ifcfg-eth2[code]...

Now what happens defies explanation. The only way I can be sure to make the e1000e first-listed-in-pci-order e1000e device always eth0 is to remake the initrd and add e1000e to the initrd.If I do not do that, eth0 might be the onboard night, it can also be the first port on either of the dual port cards.So eth0, eth2 and eth4 all take turns being eth0. This was not an issue in the EL-5.1 timeframe. This is certainly new to the EL-5.2 timeframe and thus far is not possible to control because the system does not load eth0's driver alias in order, and the enumeration of the PCI devices causes what seems to be random labeling of the first interface.

This is a particular problem in that identical hardware systems will come up with different eth0 interfaces , and on a single system, without the /etc/sysconfig/hwconf (which calls "eth0" something different from what was originally in the /etc/sysconfig/network-scripts/ifcfg-eth0 HWADDR directive).I need as little auto-magic as possible, I can live with PCI-bus order and driver load order is the order ethernet devices appear in, I cannot use the software in a state where what is "eth0" is randomly determined and the only way I can nail it down is to run kudzu, generate a hwconf AND brand the network interfaces in the network-scripts with HWADDR. I've been using EL since 6.2 and this is the first time I've ever encountered a situation where the enumeration rules (which are ancient at this point) over-ridden by something.

Version-Release number of selected component (if applicable): EL-5.2 series.The random enumeration of PCI devices and the subsequent assigning of eth0 to a random NIC is not on every reboot, and does not seem tied to a power off scenario vs a simple reset or warm reboot. Over the course of 0 reboots , eth0 should have moved between 2-3 times.Packages that seem relevant.

CentOS 5 :: It Does Not Recognise The Eth0 Ethernet Card?

Feb 9, 2010

I am attempting to install centos5 x86_64 on to an HP Compaq 6820s laptop.It appears the installation has gone ok but I have a big problem in that the centos installation knows nothing about the hardware on the laptop. i.e. it does not recognise the eth0 ethernet card.this means that I have no way of assigning an IP address to the laptop which means that it cannot join the network or the internet.how do you go about getting the correct drivers for the hardware that you are using?

General :: Stop And Restart Ethernet Connection Ubuntu 9.10 - Ignoring Unknown Interface Eth0=eth0

Mar 8, 2010

If I uncheck and recheck "Enable Networking" in the Network Manager Applet 0.7.996 I would expect the wired network to disconnect (which it does) and reconnect (which it does NOT). So I tried sudo ifdown eth0 and got

ifconfig tells me

so I am at a loss. How do I stop and restart the network interface short of rebooting the machine?

Networking :: No Eth0, Driver For Ethernet Controller Issue ?

Jul 3, 2011

i am having issues with networking on a certain liveCD.all ubuntu installs ive done on this machine im sure work fine, but i may have had issues with older backtrack versions.My issue is no networking on boot of SamuraiWTF, for those unfamiliar its based on ubuntu 9.04 There is nothing except lo loopback when i run 'ifconfig', and there is nothing in /etc/network/interfaces for eth0 either.

lspci shows a Broadcom driver, but the same command shows the model number etc on a newer ubuntu install on the same machine. This is:

Broadcom NetLink BCM57780

I have the latest .tar.gz of the tg3 drivers suggested by Broadcom, but im lost on how to install them.

-------------------------------------------------------
EDIT: it seems to be an issue with earlier kernels, i installed 2.6.35 and it worked but the kernel isnt mean for 9.04 i dont think, and now theres issues with the nvidia card

problem is i cant connect to both the eth0 and eth1 at the same time. i have to disconnect one of them to connect to the other. and this really gets irritating as it doesnt always work as flawlessly as it should. what am i doing wrong?

Ubuntu Networking :: Activate Wireless Drivers With No Ethernet Connection?

Sep 26, 2010

I'm been wanting to try Ubuntu for a while now, and when my mom's netbook started to get insanely slow with WinXP, I tried the Netbook Remix on a USB stick. I LOVE it, except I am unable to get the wireless working, which is the only thing stopping me right now from a full install.

I believe my problem is that I need to activate the two drivers "Broadcom B43 wireless driver" and "Broadcom STA wireless driver" which appear as unactivated when I go into the hardware drivers admin tools. Unfortunately this netbook (HP Mini Netbook FW376UA) does not have an Ethernet port, so I can't just temporarily hard wire it to activate these drivers.

So my main questions are: 1) How can I activate those drivers without an internet connection?, and 2) Do you think that activating these drivers is indeed the answer to getting the wireless working?

The details:
Machine: HP Mini Netbook FW376UA
Network Controller: Broadcom Corporation BCM4312 802.11b/g
Ubuntu version: Ubuntu 10.04 Netbook

Ubuntu Networking :: Install Drivers For Wireless Or Ethernet Without Make?

May 12, 2011

I absolutely love Lubuntu on VirtualBox. I installed it to my Compaq Mini CQ-10 without issue. However, there are no drivers for the Wireless or the NIC. Ok, so I go to Broadcom and download the drivers. But, when I try to install with the Makefile, Terminal tells me that make is not installed! Now, how do I install my drivers without make?

General :: Ethernet Interface Not Found - Eth0

Jul 19, 2011

I booted an OS from a live CD. The OS boots successfully but eth0 fails to start. I checked lspci, it outputs these Ethernet card details:

(Broadcom Netextreme II BCM5716 GBabyte ethernet)

ifconfig -a returns only the loopback interfaces lo and sit0. The output of dmesg | grep -I 'eth' is:

"Netfront : initializing network ethernet driver"

When I run service network restart I get:

"Obtaining IP for lo [FAILED]
WARNING: Deprecated config gile /etc/modprobe.conf , all config files belong into /etc/modprobe.d/
Device eth0 does not seem to be present, delaying initialization [FAILED]"

The output of MII-tool -v is:

No MII interface found.

I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it.

CentOS 5 Networking :: Fails At Determining IP Information For Eth0?

Oct 7, 2009

I have been running into network issues lately with my CentOS 5 (installed on AMD Athlon X2 - 64 bit machine about 2 years ago). It was able to connect to the network fine until yesterday when I installed more memory into the machine restarted it.

Upon restart, the boot up was paused at 'Determining IP information for eth0' step for a while and booted with out connecting to the network. I tried restarting the network (/sbin/service network restart), but this is the error message I continuously get: Determining IP information for eth0...PING xxx.1.226.1 (xxx.1.226.1) from xxx.1.226.83 eth0: 56(84) bytes of data

CentOS 5 Networking :: Another Determining IP Information For Eth0... Failed?

Apr 1, 2010

I've seen this pop up a few times on the forum but my setup is slightly different. I have a PC with an ASUS P5N32-SLI Premium motherboard. I've just installed CentOS 5.1. Yes, I know this is ancient, but this is what they're developing on at work. I'm trying to get connected either via ethernet or wireless and neither one works. When I boot the computer to Window XP it does connect on ethernet. Ethernet should be easy so I'm concentrating on that. But I get "Determining IP information for eth0... failed." after a 'service network start'.Here is some other information that was asked on similar threads:

> uname -rmi

CentOS 5 Networking :: Eth0 Takes Traffic Of Eth1?

Oct 18, 2010

I'm having a problem and despite I have googled a lot cant find the root cause. I have a server with two embedded NICs and centos 5.5 loaded. I need to have one NIC with a fix internal IP address to communicate with the intranet and a second NIC with a fix address from my telephone provider. I know I cant have two different gateways on the net so I configured only the gateway for the second NIC leaving the field empty for the first.

I found that the first NIC is handling all the traffic for both interfaces (eth0 and eth1) and the second NIC is in standby (or doing nothing). This is causing the traffic intended for the second NIC never reach their destination. After a couple days working with the BIOS and other configuration files I tried another way of solve the issue. I put a fix address for the first NIC and another fix address for the second NIC (both in the same subnet) and from a computer pinged successfully both addresses. However if I disconnect the cable for the first NIC both interfaces goes down (eth0 and eth1) and both pings fails. If I disconnect the cable for the second NIC (with the first one connected) both pings still running without any disturbance.

I worked also in a second server with different hardware (different kind of motherboard, different NIC manufacturer, etc.) but the problem is also present in this second server. I was reading about NIC bonding or teaming, but this configuration is not present in the modprobe.conf or in the ifcfg-eth0 files, so I believe the problem is not related with this feature. Do you know what is happening with the NICs and how can I get two really, fully independent NICs?

CentOS 5 Networking :: Eth0 Now Broken After Last Kernel Update

Nov 23, 2010

I am currently working to get to a stable dual boot Win7/CentOS 5.5 configuration on a Dell Latitude E6510 with the Intel 82577LM chipset. I haven't gotten the Centrino N WiFI chipset working yet, but the Eth0 device was working just fine.However, yesterday I did a system update. I did not pay close attention, but I believe the update did mention networking, because I thought it might help me get my wireless going. Now, Eth0 fails with the message, "Determining IP information for eth0... failed; no link present. Check cable?" It does this at boot up and if we try reactivating it once the system is up. We have tried unstalling and re-installing the driver.The Window 7 boot sees the adapter and runs just fine. I was at a different site location yesterday when everything was working, but my co-workers and I can't help but think it might be related to the update yesterday, since everything worked prior to the update and Windoze 7 works fine with the adapter.

I have not been able to mount my NTFS harddrive on the CentOS side, despite installing fuse, and I don't have wireless, which makes it difficult to get access to new drivers. I also have a FAT32 partition that would be great to share between the boots for passing info, but I haven't found a way to mount a FAT32 partition in CentOS.

CentOS 5 Networking :: Secondary IP Address Won't Work On Eth0

Everything worked fine until very recently, and without apparently ANY change to the settings on the server, a secondary IP that was assigned to my server won't work anymore..Any IP attached to the same server works fine.. So in my case, the problematic IP is 213.8.155.67. The other IP (213.8.155.42) works without any problem.How would I go about troubleshooting this?
