similar to: network config files in centos 5 changing

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

I am doing a yum install netconfig on the new 5.1 and nothing gets installed. Was it removed? replaced with something else? yum provides netconfig does not show a "bin" command just false matches. Is there a new command? Thanks, Jerry

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

Me again. The ASUS P5N32-SLI motherboard in my new machine has dual NICs but CentOS has only detected one of them. I've tried rebooting with the network plugged in only to the second one, but kudzu still doesn't find it. Any suggestions?

Actually, here is what shows up in the log, regardless of whether the driver is built-in or loaded as a module: Feb 5 10:16:15 sparenode1 sysctl: net.ipv4.conf.default.rp_filter = 1 Feb 5 10:16:15 sparenode1 sysctl: net.ipv4.conf.default.accept_source_route = 0 Feb 5 10:16:15 sparenode1 sysctl: kernel.sysrq = 0 Feb 5 10:16:15 sparenode1 sysctl: kernel.core_uses_pid = 1 Feb 5 10:16:15 sparenode1

I have two servers with identical hardware ... TYAN i3210w system boards with dual intel gigabit interfaces, and a PCI intel gigabit nic. I'm running Centos 5.4, x86_64, 2.6.18-164.6.1.el5 Every other time I reboot, the nics initialize in a different order. anaconda had setup /etc/modprobe.conf with alias lines for the cards: alias eth0 e1000 alias eth1 e1000e alias eth2 e1000e However,

1) I'm actually not building a custom kernel per se, just one from the standard 2.6.11.4 with our configuration. I may be adding a custom driver, but unless I can get the standard kernel to boot,... 2) I have been told that after 2.6.11.4, support for the Infiniband driver is dropped, and we need that. If this is not the case, I would be delighted to know that and proceed accordingly.

I am new to CentOS (coming from Fedora) and I really like it! I am having difficulty getting one of my machines to boot and assign the same designation of eth0 and eth1 to the same nics consistantly. I have an MSI motherboard with 2 nics on the board. Strangely enough both nics report the same MAC address. This is not an issue since I use the computer to route between two different subnets so

Hi On a multihomed box how can i set different gateways for each NIC? Setting them in the ifcfg-ethx does not seem to make any difference to the routing? thanks

I am running Asterisk at home on one of my systems here. It uses Centos 4.2. It does NOT have a GUI interface. Command line only at console or via SSH (yeah, I know that I was working on another server to get GUI tools working through SSH, but I am NOT going to muck with AAH build). yum update is potentially dangerous, when it replaces the kernel. You can loose all of your Zaptel driver

All, I've got a machine running CentOS 5.3 and this machine has got 2 - built-in 1 Gig NICs and a expansion card with 4 - 100 Meg NICs. For whatever reason at install time, it made the expansion card eth0 through eth3 and the internal ports eth4 and eth5. And by default the 'machine' is known on the network by the eth0 NIC, so my throughput is limited to 100 Mb. How can I force

I am using centos 5 x86_64 AMD64 X2 4200+. I am current on yum update. My machine has two ethernet cards. e1000 (eth0) and forcedeth (eth1) [root at fsdsigns2 ~]# more /etc/modprobe.conf alias eth0 e1000 alias eth1 forcedeth sometimes on boot the forcedeth driver thinks it is eth0: [root at fsdsigns2 ~]# dmesg | grep eth forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.60.

I''m in a bit of a pickle and I can''t work out a safe way to do something. I currently have a define called ip that I use to define network interfaces. The built in method didn''t seem to work, so I designed this to write out the /etc/sysconfig/network-scripts/ifcfg- ethX file. However, I started thinking about what if I decide to define an eth0:0 for some purpose, and

I want to move all my OS, services like Apache configuration and application (web server) files and folders to another brand new server. Both servers are running on Centos 7. i want to clone everything. My questions 1- what is the easiest way to do this? 2- do I need to partition hard-drive of new server exactly as old one? 3- Is there any changes to make on new server after full migration? 4-

Looks like there are NO command line options on system-config-network. Like -d eth0 or -d eth1 I used those alot when 2 network cards are in a box. Can netconfig be brought back to life? Can I just install the one from 5.0 on new boxes?\ Jerry

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

Is anyone frustrated by Network Manager? I wish CentOS just used the basic configuration files like the ones on BSD-style OSes. Those are so simple in comparison. Each time I reboot, it seems like the configuration file I create for Network Manager gets destroyed and replaced with a default file. Nothing in the default file would actually make sense on my network, so I'm not even really sure

Hi all, I have a CentOS 5.4 server-only installation, i.e. no X installed, and for some odd reason /etc/resolve.conf gets overwritten by NetworkManager on a constant basis. I haven't been able to track down how often, but I think it's on the hour, or something. This is the conents of the file right now: # Generated by NetworkManager # No nameservers found; try putting DNS servers into
