CentOS 5 Networking :: No Link Lights On Any Nic Poweredge 4400
Aug 24, 2010
I'm running a Poweredge 4400 with a 3com card and an intel card covered under e100.
I'm using centos 5.5 in its default server config coming from gentoo.
I have no link on either of the two interfaces, ever. The card initialises with ADDRCONF(NETDEV_UP): eth0: link is not ready and then falls back to half duplex but still with no connection.
I have manipulated most of the general settings that can be changed with ethtool.
Set to manual configuration with 100/full duplex
The cards are recognized alone and together. I have setup static interfaces with no problems. The ping to the local interface such that:
nic = 192.168.1.10
ping 192.168.1.10
we get back route times and all is well
ping 192.168.1.1
no route...
I have tried several different cables verified good other connections. I have verified the ports I am connecting to work correctly. I have manually shut down the onboard nic (in bios) and tried the 3com card alone. I have tried pci=routeirq, thinking there might be an irq issue.
If this was just the one card, I would install another and move on, but both nics are acting in exactly the same way.

I have a Dell PowerEdge 1950 with Centos 5.4 installed. I am having an issue where there is no network activity on any of the NIC's.(Broadcom and Intel).
I have read that this might be somewhat common but have not found any solutions. I am unable to ping anything internal or external. Has anyone encountered this problem and have a potential fix?

I picked up the computer for free (Dell P4 with no HD), stuck in a hard drive I had laying around and installed Ubuntu Studio 10.04 yesterday. I am completely clueless about how to do anything with Linux. I put in a Zyxel g-360 wireless pci card, and found the ACX111 driver online. I found the wiki here: [URL] Are those installation instructions? I can't understand what it says. I have the Zyxel installation disk for Windows XP if that helps.

I am trying to install CentOS 5.5 on a older Dell PowerEdge 2450. Is there any reason the install would fail? It does load the initial install screen but when I hit enter, it simply goes to a blank screen with a blinking cursor ( I want to say that it says to me "What are you doing Dave?"), but I won't. It just sits there on this screen.

I have two Dell PowerEdge 2650 servers. One is a dual Xeon 3GHz with 4GB of RAM (4 x 1GB sticks). The other is a single Xeon 2.4GHz with 3GB of RAM (2 x 512MB and 2 x 1Gb sticks).
Both are running 32 bit CentOS 5.3. Both are running the same kernel (vmlinuz-2.6.18-164.el5). I've even diff'ed the two kernels to ensure that they are in fact identical. The only parameters being passed to the kernel via the grub config are "ro root=/dev/sda2"
The BIOS shows 4GB detected on the 4GB server and 3Gb detected on the 3GB server on boot.
Dell OpenManage for the 4GB server shows "Total Installed Capacity 4096 MB, Available to the OS 3804 MB", as I would expect. However, OpenManage for the 3GB server shows "Total Installed Capacity 3072 MB, Available to the OS 1011 MB". (i.e. it is only seeing the first 1Gb of memory).
cat /proc/meminfo confirms the above; the 4GB server shows "MemTotal: 3895980 kB", but the 3GB server shows "MemTotal: 1035024 kB"
I installed the lshw utility, and on the 3GB server it shows all 4 memory sticks, the full 3GB:
*-memory
description: System Memory
physical id: 1000
slot: System board or motherboard

I have a problem. I want interface to shut down once there is a link down state detected. If you set up eth0, and then plug cable out, eth0 stays up, just loosing the RUNNING flag. I want it to go down completely.
I've stumbled upon netplugd, and I've tried using it. It is a daemon that detects states in (link up) and out (link down) from kernel netlink interface. If I have this daemon up, it detects that link is down (eg. cable removed from interface), and it runs correctly /etc/netplug.d/netplug eth0 out. That script then runs ifdown eth0. And that's ok.
But very next moment netplugd runs /etc/netplug.d/netplug eth0 probe, and probe section of that script runs "ip link set eth0 up", which then turns interface back on!I've tried commenting out that line, but then new problem occurs - after the link is up, netplug cannot figure that out and bring back interface. Has anyone have this kind of problem, and any viable solution with netplug?

I want to change one of our poweredge 6450 servers over to Linux, specifically CentOS, however, I cannot seem to install the operating system. When I boot to setup, go through the first couple of pages and then go to the page that asks you where to install CentOS, no drives are shown in the list, and I can't continue. I'm guessing there are missing drivers for the SCSI controller or something along that lines, but I'm not sure, and I can't find any answers on Google either.

I am having issues installing Centos on a Dell Poweredge 1950. I have tried 5.3 and 5.4, and the text only install. The error I get is when I select what keyboard layout to use. An error window pops up and says "Assertion ((C * heads + H) * sector + S == A) at dos.c:624 in function probe_partition_for_geom() failed " I can click ignore and cancel but it instantly pops back up. I have tried to look up the error but can't find any information on it.

we have 22 servers Dell (20 Poweredge R210 + 2 Poweredge R310) with CentOS 5.5 x86_64 (kernel 2.6.18-194.26.1.el5). Half of these are on different rack. During the day, some server reboot without any reason and the messages log file had no evidence of what happened.
From /var/log/messages:
...
Dec 8 14:10:02 hadoop011 snmpd[3029]: Received SNMP packet(s) from UDP: [172.27.1.21]:50825
Dec 8 14:10:02 hadoop011 snmpd[3029]: Connection from UDP: [172.27.1.21]:50825
Dec 8 14:15:26 hadoop011 syslogd 1.4.1: restart.
[Code].....
Some minutes after the reboot, messages log this error: Dec 8 14:18:14 hadoop011 Server Administrator: Instrumentation Service EventID: 1404 Memory device status is critical Memory device location: DIMM_A3 Possible memory module event cause:Multi bit error encountered.
Is it possible that 20% (circa) of 60 memory bank are broken? By the way, memory bank have Lifetime warranty from Kingston. If I reboot again the server affected by this error, the error disappear from messages log file and from OpenManage Web interface.
Is it possible that is a CentOS bug? I had search some relative bugs on Bugzilla but without any results.

I am trying to install Centos onto a Poweredge 2650, with Dell Poweredge Expandable Raid Controller. I have 5 SCSI disks installed, and have created and initialised 2 logical volumes via the SCSI controller setup utility (Ctrl M after boot). After reboot the system reports two logical volumes present.
The Centos installer cannot find any disks when it gets to the disk partitioning/setup step. It reports no disks present. Do I need a specific driver for this controller?

i am getting really pissed off with my new core i5 system I have a gigabyte p55m-ud2 mobo ([URL]) which's got a Realtek 8111D lan chipset it connected to my router after fresh install of ubun10 and then i installed MacOSX 10.6.3 and it worked there too then i came back to ubuntu and it didn't work anymore, after several restarts it was still not working until i took out the power cord and mobo battery, and reinstalled them back later which caused ethernet to work once again. but then after a while it started not to work anymore, which usually got fixed with a reboot. now this time i had ethernet working and i just resumed from screensaver and it stopped agian
there are no green or orange lights flashing at the back and when i take the cable out and reinsert it nothing comes on but with a shutdown they do come on i don't have this problem on the other harddisk which now has win7 and i some times manually change the sata cable to boot into windows and use itunes and some other stuff to load music to my iphone. I dont like to have dualboot and i dont like to use win7 either i just have it on the other hard disk just in case
is the manual switching of hard disk causing this to happen? why do i get it working with restart/shutdown and when i am using it fine it just decides to stop working after a resume from screensaver or sometimes for other reasons and why does none of this happen on win7 is there a way to reconfigure the ethernet drivers or other stuff without a reboot i am thinking it might be a problem with network manager or a bug or something network manager is really crappy and i used to use wicd until that started to do funky things ( like not connecting to hidden networks, launchpad Bug #473817)

I have a problem where I'm using Ubuntu linux to mount a Windows Vista machine's USB drive and access it on the web using Apache. I did have the USB drive plugged into the Linux machine directly and that was working via the web. FollowSymLinks is on in httpd.conf
[Code]....
The mount works and I can see the files (see above) from my regular linux user account. If I make a test file in /mnt and soft link to that, I can see it on the web. So it's just the mount to the vista machine that seems to be a problem. It's supposed to be a simple read-only mount and the apache login should (I think) be able to see the same generic root access permissions.
log from apache: [Mon Apr 26 20:39:42 2010] [error] [client 99.99.99.99] Symbolic link not allowed or link target not accessible: /home/user1/pub_html/Music, referer: https://xx.xx.xx/~user1/music.html
The credentials have a login and password that matches a special read-only account on Vista. I can see the files on the system from Linux, but not via the web. As mentioned above, a different link to the same /mnt area works fine via the web. I've tried several different mount options with no success.

I have a desktop that has a d-link DWL-520 wireless card, which was working under Windoze. Today I installed Centos 5.4 on the system , which went cleanly. I then used Network Configuration to set up the wireless card. I specified to use DHCP, set the SSID and authentication password. When I tried to activate the card I get these error messages
Error for wireless request "Set Mode" (8B06): SET failed on device wlan0 ; Operation not supported. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid argument. Determining IP information for wlan0.
The hardware manager seems to have correctly identified the card and chipset, (Intersil Prism 2.5) and installed driver hostap_pci which came with the distro. This web site seems to suggest that this is the correct driver: [URL] searching forums I've found a few references to these errors, but they were from several years ago, and for different distros and cards. I did find a reference to using Network Manager to configure the card instead of Network Configuration. I started the NM service and configured a connection using it instead, but still no luck.

I have a problem with my network interfaces on Dell poweredge server. I have two broadcom 5708 Gigabit network cards and they were working fine with my old kernel (2.6.18). recently, i have updated the kernel to 2.6.35(actually installed a new distribution Ubuntu 10.10) Since then, I have problem connecting to my server, the output of ifconfig shows that both NIC`s are working and assigned IP, i can connect to the system from both local machines and through internet. but sometimes suddenly the connection through internet is disconnected (some times to one NIC and sometimes to both!).
here is the result of:
$ethtool -i eth#
driver: bnx2
version: 2.0.15
firmware-version: 5.2.7 bc 5.0.4 ipms 1.6.0
bus-info: 0000:06:00.0
I was wondering if anyone here has had the same problem before and can share a solution with me?

When I select any option under Partitioning of your hard drive, it gives me an error. " No Drives found - An error has occured - no valid devices were found on which to create new file systems.

I recently bought a D-Link DWA-140 USB wifi adapter for use with my CentOS 2.6.18-194.el5 hoping that it would work seamlessly due to its popularity but having issues with it.
The USB adapter is detected in the System > Administration > Hardware.
It also appears in lsusb:
but when I went into System > Administration > Network it does not appear in the Hardware tab.
After some searching I found out that I need to install some packages which I did.
Namely, rt2870-firmware rpm and kmod-rt2870sta
Then I turned NetworkManager on as a service and through the docked applet on the top menu bar I was able to connect to my wifi net.
However when I rebooted the connection wasn't re-established and when I click on the NetworkManager applet icon it tells me "No network devices available"
Where did my USB adapter and joy go? :(
I can't for the life of me get the adapter to re-surface even if I go to System > Administration > Network and try create a new interface.
No devices appear there in the Devices tab and nothing in the Hardware tab.

I am Setting up 3 HP Proliant servers with 2 250GB Hard Drives in each. How Do I mirror the drives, and link all the servers together??? I am installing Centos 5.3. From the software install menu I installed Gnome, and the Server software, but can't seem to figure out how to get into the server side of it from gnome. Sorry for all the questions, but I have been out of the loop of all this for about 8 years and trying to re-learn everything.

CentOS 5.2. I have D-Link WUA-1340 wireless USB adapter that uses the rt73usb driver / module. At least I worked in Fedora 9 out of the box with that driver / module. I assume the Fedora 9 kernel supported it.
I really do not want to try and add a custom kernel to my instalation but I am wondering how I can get this to work on centOS 5.2.
I know first step is to get the adapter to be recognized by the system kernel. I think I can configure the network after that.
