What is happening in centos 5 with network config files??? I have a machine with 2 network cards. ifcfg-eth1 keeps changing to DHCP. All my static setup is gone. Why is it doing this? How can I stop it? I run "netconfig -d eth1" and re-setup my static information. I reboot and now I am back to DHCP. I have a gigabyte motherboard, nvidia chipset. forcedeth driver. eth0 is e1000.

I am attempting to put 3 network cards in one box, running centos 64 5.4 network cards are forcedeth (motherboard), e1000e and r8169. I have ifcfg-eth0, ifcfg-eth1 and ifcfg-eth2 all configured up. All looks fine. eth0 is my internal network (forcedeth) eth1 is Cable modem eth2 is T1 data Once I connect the three networks and try to ping something all I can ping is internal network machines.

centos 5 had modprobe.conf entries for eth0 and if present eth1. something like: alias eth0 forcedeth alias eth1 e1000e For the new centos 6 (I have the rhel 6 client installed on my laptop) the modprobe.conf file is gone. Which is fine. I understand files can be created in /etc/modprobe.d and server the same purpose. My question is I dont see (doing a grep) any eth0 alias's in the files in

Seems like overnight every motherboard that worked with linux has DROPPED off the face of the earth. Every motherboard I looked at is using the realtek 8111 chipset and a northbridge that is not supported. Example: GIGABYTE GA-970A-DS3, does not work with linux I tried disabling the onboard NIC and using a PCI-E intel card I always use and that would not work either. The north or south bridge

I need to change the host name on a test server, and in the past when I used hostname to change the hostname, it did not seem to change it everywhere. I really don't want to do a rebuild just yet, but I have to feel confident that hostname is really changed (reboot is not too much of an issue). What is the recommened practice? Other than get it right the first time.

I have a USB to ethernet device connected to CentOS 6.5 on my laptop. I setup ifcfg-eth0 and added BRIDGE=br0 on eth0 did service network restart, all came up. "seems" to be working. However when I plug an ethernet device into the USB port that is wanting DHCP it is not getting an address. Is there something I missed in the setup? I was expecting the device connected to the USB to

I have a machine with 2 network cards. Installing centos 5 on it. I set up both cards with static IP addresses. activate on boot etc... One is e1000 Intel the other is onboard forcedeth (nvidia). After I reboot the forcedeth ifcfg-eth1 file is changed to DHCP. I use netconfig -d eth1 to set it back up and reboot again and the changes back to DHCP. Only thing to add here is the network card

I just installed a KVM guest, centos 6.2 i686 (6.2 x86_64 host) and the network module is loaded . The modules is/are 8139too,8139cp is what lsmod shows. Dmesg shows link up but ifconfig does not give me an address? service network restart shows OK no errors but again no address. I set the ifcfg-eth0 file to not be NM controlled, onboot yes and rebooted. Same no address. I run 5.8 images all

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

Hello CentOS gurus, and a belated Happy New Year (or an early Happy Chinese New Year). I'm in the process of building a CentOS-6 KVM host machine whose only function will be to run four independent 'm0n0wall' firewall guest instances. I have a couple of quad-port Intel NICs to provide four WAN-side and four LAN-side ports, which will not be shared with any other guests. Remote

Hello, My name is Manfred. I have to install a flexlm license server on a pc with centos 6.3 as operating system. This machine contains two network cards. An Ethernet card and a wifi card. For the Ethernet card centos generates a device called p3p2. For the wifi card centos generates a device called wlan0. In this configuration the flexlm license program called lmgrd only got the mac address of

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

I installed 7.1 with the command line values biosdevname=0 net.ifnames=0 thinking this would result in ifcfg-eth0 being the file to use... The system still created an ifcfg-eno1 file and that was what is being used for network config information. I remove the ifcfg-eno1 and rebooted - got no network. I then copied back the ifcfg-eth0 to ifcfg-en01 and changed the device name in the file and

Hello. I desire to get bridge network working using virt-manager. Centos 7 and centos 7 guest. >From researching I think I need to have a ifcfg-br0 file like this ? cat ifcfg-br0 DEVICE=nm-bridge0 STP=no TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.8 PREFIX=32 GATEWAY=192.168.1.1 IPV6INIT=no NAME=br0 ONBOOT=yes DELAY=0 Is that for sure needed ? The use that nm-bridge0 as the network name? I

Just installed centos 6.2. I run and ifconfig -a I see and em1 em2 and lo interface. If I go to /etc/sysconfig/network-scripts, I don't see an ifcfg-eth0. If I run ifup eth0 it comes back with "Device eth0 does not seem to be present, delaying initialization". Anybody have a clue? Thanks in advance.

I have not see this before... Installing centos 5 on m2n-mx motherboard the onboard forcedeth driver loads and says invalid mac address "97:42:40:F3:18:00" Anyone else ever seen this before? Is it fixable? I went to support.asus.com and searched for "invalid mac address" they say sorry no data. Jerry

Hi all, With help from others, I''ve been able to get Olaf''s patch for enabling MTUs >1500 for vifX.y and tapZ devices working. I''ve been able to boot dom0, launch domU and live-migrate without having the bridge''s MTU degrade at any time. Would the Xen RPM maintainers (and others) mind taking a look at the following patches? Kernel part:

Define out of order in this case just so I know for sure what you mean. What my solution does, or at least does reliably in my case, is make sure the interfaces are in the same order once installed as the install kernel saw them. It won't re-order them to be sequential based on bus, mac or driver. I am working on that but it will also include naming the devices based on the module

I have need to use the old network-scripts and not NetworkManager. I did yum install network-scripts, I have ifcfg-eth0 set for ONBOOT=yes but it is not starting on boot. What have I missed ? Jerry

So I just finished doing a fresh install of CentOS 6.3. The machine has three ethernet ports in it: one on the motherboard (VIA Rhine), and two add-on cards, an Intel Pro100 and an old SMC1255TX. When CentOS comes up, this is what I see in the dmesg output: # dmesg | grep eth e100 0000:00:08.0: eth0: addr 0xf6043000, irq 16, MAC addr 00:02:b3:be:02:87 eth1: ADMtek Comet rev 17
