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:
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
I'm running a fresh install on an intel i7 system on an asus p6t deluxe v2 motherboard with the onboard NIC (Marvell Technology pci-e). I know the NIC is working as when I boot into the onboard OS that Asus provides (Asus Express Gate SSD)I have a working net connection.Booting up CentOS hangs at determining IP information for eth0 and eventually fails with the following error:PING xxx.170.30.1 from xxx.170.31.231 eth0: 56(84) bytes of data---xxx.170.30.1 ping statistics ---4 packets transmitted, o received, +3 errors, 100% packet loss, time 2999ms, pipe 3 failed.
i wanted to learn linux, so i just installed Centos on a thinkpad x200. my wireless will not work. when i try to activate it i get this error:
Determining IP information for wlan0...SIOCSIFFLAGS: No such file or directory SIOCSIFFLAGS: No such file or directory # lspci 00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
I have 2 network cards eth0 and eth1, for eth0 i set a manual MACADDR in network scripts. Ok so every time i boot, if the cable is plugged in, my eth0 fails to mount or i don't know.. i get this after bood when i type ifoncifg eth0 (eth0: error fetching interface information:Device not found). So i have to unplug the cable when i boot, then plug it in and do a service network restart.
My network name is eth2 it was changed by some reason and now i got these errors... i installed, reinstalled, re re installed, tried to run the asistant but no luck :/
Code:
* Stopping the Firestarter firewall... eth0: error fetching interface information: Device not found eth0: error fetching interface information: Device not found eth0: error fetching interface information: Device not found
I have a question regarding the configuration of Network Connection. My wired connection is fine right now and when I check the network connection applet, it display active information of eth0. However, when I click the Configure button, the Network Connection window appears but there's nothing in the Wired panel. Should there be a eth0 in that panel? I remember I had one before, but after I messed with some configuration of VPN, my network became unstable and I remove the Network Manager to try to solve the problem. Since then, there's nothing in my Network Connection window, though I can still connect to my router with eth0. Now even after I reinstalled the Network Manager, I still don't get anything.
I ran the 11.04 upgrade. At the end, it reported a failure, implied a recovery would occur and the upgrade then finished. The recovery was supposed to have run sudo dpkg --configure -a. That does not appear to have happened. I am concerned that a reboot will render my system inoperative.Has anyone else experienced a similar issue or have any suggestions? What information should I provide. report.
i install kernel rpm after i boot that kernel network not working kernel name : kernel-rt-trace-2.6.24.7-132.el5.centos.i686 [URL] error "Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring."
I installed the Ubuntu Desktop 10.4 on my new MacBook Pro under a Parallels Desktop (VM).The install wend fine and after rebooting I was a happy new Ubuntu user.Had to reconfigure the ethernet port of my virtual machine and I had internet access.After 5 minutes, Ubuntu displayed a message that there were updates available, which I ran successfully.After the reboot however I got the following message :"An error occurred while mounting /media/psfPress S to skip mounting or M for manual recovery"After pressing M, a maintenance shell started under "root@ubuntu".As new user, I did not want to mess around as root (I would know what to enter).So I pressed ctrl-D which brought me back to the above message and I typed S.Ubuntu started ok however I lost my eth0 interface.In the network tools, I only find the Loopback interface, no eth0 anymore.Do I have to reinstall from scratch ?
Yesterday I did an upgrade and today my box is unable to connect to the internet.
I have tried another cable, it didn't help.
Basically NetworkManager does not connect eth0 to the network, if I try to run ifup from the command line I get:
Code:
I can see in network configuration settings, that the device has been correctly detected and eth0 interface is correctly activated, yet when I try to uncheck the box manage by NetworkManager and start it manually, it tells me that the cable is disconnected... I've tried two different cables, different ports on my router - no help.
Eth0 and Eth1 is bonded and works fine but when i reboot the OS eth0 and eth1 cant be up when i run command "ifup bond0", it gives me following message.
OS information:
Network Card :
I am using above card , it works perfectly fine and I have bonded but when I reboot , eth0 and eth1 looses this driver and also the RPMS I have installed , they are gone too.
Installed Centos 5 on IBM T60P laptop. Intel 82573L Gigabit ethernet controller. Keep getting this erro message, "e1000 device eth0 does not seem to be present, delaying initialization."
When I attempt to add software i get the following error:
Unable to Retrieve Software Information
This could be caused by not having available connection.
Cannot find a valid baseurl for repo: addons
To get my browser to work properly, I have to specify a proxy (manual) and use the IP address of our proxy server. After this, I'm able to get out through the internet using my browser. Not sure why I fail to get software updates though. I used the same setting in Proxy - Control Center. Repository Manager show's CentOS-5 - Addons mirror list as :

I have a Proliant DL 120 G5 with CentOS 5.4 and I have installed a Brodcom Corporation Netxtrem BCM 5722 Gigabit Ethernet PCI. So I have two interfaces: eth0 broadcom eth1 Intel The eth1 works, instead eth0 don't work. I can ping itself and 127.0.0.1 but I can't ping the gateway. The results of netstat -nr is:
New to CentOS5.5 I'm experiencing some trouble in order to continue my configuration. I've just installed my vmware tools and configured my network card with system-config-network
Edit eth0 (eth0) - vmxnet3 -> with a static IP I rebooted my server and since then I lost my eth0. I still see it in system-config-network, but I can't active it anymore.:
/etc/init.d/network start Bringing up interface eth0: Device eth0 has different MAC address than expected, ignoring. [FAILED]
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?
I have 2 network interface on 1 server and i got a problem finding a solution for it.I have 1 java application and i want it to use the eth1 for that application and not the default eth0. On eth0 i got for example xx.xxx.xx.22 and on eth1 i got xx.xxx.xx.23 and i want the java app to use the 23 ip one.
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.
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?

Looking at the output of netstat, I'm not seeing a definitive way to tell which torrent connections are clients reaching in to my machine vs my machine reaching out to the world. Is there a clear way to determine which is which?
i've configured my laptop so i can use my domain account (active directory win 2003 DC) to logon to my machine. Now i'd like to browse and mount shares etc using my logon information. Now when i connect to a share with nautilus it tells me 'guest' can't log in and i need to re-enter my user info. This is a real pain since our passwords change often. Is there some way i can use PAM to authenticate? I've searched everywhere, but you only find info about the other way round (win->linux).
I've been racking my brains over the past few days trying to figure out why my NIC card (network interface card) won't show up in the ifcfg-eth0 file.When I configure a new server (like this one) I always go to:/etc/sysconfig/network-scripts/ifcfg-eth0 and from there I usally see the name of my NIC's manufacturer's name and the hardware MAC address.Then it's only a simple process of entering the server's IP address, netmask and gateway and I'm up and running in no time...But not in this case! the ifcfg-eth0 file is completely blank! There's not ONE single line of config info in it... (?)The server runs an Intel core 2 duo (dual-core) CPU with 1 gig of RAM.
I've even re-formatted the drive and re-installed Centos 5.1 on the darn thing 3 times and it simply won't work.The server cannot resolve when I do a wgetIt also gives me a 'resolution problem in the named configuration'.What I don't understand is that the 2 small LEDs on the Cat 5 cable lights up and flash at what appear to be regular intervals here.
I have just upgraded a CentOS 5.2 box to Centos 5.3
I did have a bridged networking setup for Virtualbox which worked well. eth0 was bridged with br0. br0 boot protocol was DHCP and it sent its DHCP_HOSTNAME to the windows DHCP servers.
since the upgrade the br0 does not get an address but the eth0 does. I found that the scripts in /etc/sysconfig/network-scripts/ifcfg-* are getting rewritten.
I figure I may not need to have a bridge any more so I stripped that out to try to get a simple network setup working. I now just have eth0. I edited /etc/sysconfig/network-scripts/ifcfg-eth0 so that it looked like this,
When I setup the server I added multiple ips. Now that I need to edit ip info I can't find any alias files in the network-scripts folder. But restarting server the ips work fine. Is there some where else that this would be stored.
I'll start by saying that most of this is built inside of a 64bit ESXi 4.1.0 server. Should be obvious by the picture below.
Trying to set up a bridged CentOS box. Ultimate goal is to set up a Transparent Firewall. The machine labeled 'Desktop' is a Windows XP running DHCP. It gets assigned an Internet routeble IP address. At this point, nothing is running a firewall.
Symptoms: Gateway can ping CentOS bridge CentOS bridge can ping gateway CentOS bridge can resolve DNS names and ping FQDNs on the Internet. CentOS bridge CAN NOT ping Desktop
