network config files in centos 5 changing
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.

future modprobe.conf
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

again, nic driver order
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

Multiple Internet facing Nics - Gateway issue
I have a server with 4 nics. Two are using different internet connections,
both with static IP's, and two are connected to our private network.
The two internet facing nics seem to be battling over the gateway
designation. Which ever I designate as the gateway the other stops
responding to incoming traffic. I need both to listen to inbound traffic.

ifconfig showing same mac for 2 nics in same bond
Hi all,
I just noticed that my two nics that are bonded via mode 0 are showing
the same mac addy in ifconfig.
Is this normal?
In syslog I keep getting;
kernel: pbond0: received packet with own address as source address
Some guidance is appreciated before I dive in and troubleshoot.
If I don't list the mac addy in my ifcfg-th# files, only one of the 2
nic comes up during boot.

Setup multiple bridges for use with KVM
Running CentOS 5.4 x64.
Have successfully bridged eth2 with br2 by following the instructions here:
http://wiki.libvirt.org/page/Networking (under the RHEL section)
Have been running several KVM VMs successfully via this bridge.
I am now trying to bridge additional interfaces by using the same routine.
Each bridge is named to correspond with the ethX device its bridged with.

machine with 2 ethernet cards e1000 and forcedeth
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:

Nic order detection
I have a number of machines that have 4 NICs, two of which are actually
in use, running Centos 5. When they are rebooted, they seem to change
the eth interface names, assigning them in different orders. I'm a
little fuzzy on the details because they are at a remote location and I
can't access them easily - especially after the network breaks. Shouldn't:

CentOS 4.x - Multiple gateways
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

virtual interfaces
I have CentOS 4 running on an old (early model) p3 with 64 MB RAM. It
is acting as a router and firewall for my LAN.
CentOS is doing a really good job with Shorewall + DHCPd - on a 10 Mbps
cable modem, I see ~ 9.7 Mbps of throughput even when numerous tcp
streams to different LAN hosts are running.
I would like to add a virtual interface to one of my LAN interfaces.

Back to eth shuffling ...
So I'm back to this problem. A quick run down of what the original problem
was:
I have a machine that I'm configuring to use kickstart to setup. It has two
builtin ethernet ports (labeled ports 1 and 2) and I'm adding a third one
on its PCIe bus. Originally I was using an r8169 clone a default kickstart
always put it as eth0 with the builtin ones as eth1 and eth2 respectively.

Centos 7 - "Device eth1 does not seem to be present, delaying initialization".
Hi All :)
I have three servers, all with centos 7 installed 3 days ago. I need on
them "old" naming scheme (ethX) for network interfaces, because of that:
# grep GRUB_CMDLINE_LINUX /etc/sysconfig/grub
GRUB_CMDLINE_LINUX="rd.lvm.lv=centos_node-XY/swap rd.lvm.lv=centos_node-XY/root

net.ifnames=0 was added and afterwards I ran:

Odd ethernet interface
Hello,
I have a CentOS 6 VM on a CentOS 6 host. This VM has two ethernet
interfaces, eth0 and eth1. It was working nice. All of a sudden eth1
stopped working as expected. Kernel started to give the message below:
kernel: udev: renamed network interface eth2 to eth2-eth1
There is no any eth2 or eth2-eth1 in /etc/sysconfig/network-scripts/. I
really don't know where it is coming from.

bogus bond0 device showing up in /proc/net/dev
I'm running into a situation where a bogus bonded interface named
"bond0" is being created, in addition to the desired "bond2" interface.
Can anyone confirm this? Anyone know why it's happening or what I do
to get rid of it? I wanted to start my numbering scheme at 2 instead of
0, which I didn't think would be a problem.
As you can see, I have no reference

How to make a network interface come up automatically on link up?
I have a recently installed Mellanox VPI interface in my server. This is
an InfiniBand interface, which, through the use of adapters, can also do
10GbE over fiber. I have one of the adapter's two ports configured for
10GbE in this way, with a point to point link to a Mac workstation with
a Myricom 10GbE card.
I've configured this interface on the Linux box (eth2) using

centos 5 is reporting invalid mac address
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.

centso 5 modifying my ifcfg-eth[x] files
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

configure network bridge listing bridged intefaces
Hi all,
Having a 4 NIC server, I want to bridge eth2 and eth3, with a bridge
named br0.
Searching the web I only found about creating a file
/etc/sysconfig/network-scripts/ifcfg-br0, but did not find where to
explicitely list what ports will be bridged.
Where is it configured?
Thank you.

Back to eth shuffling ...
When I was working on this last time (with the r8169 driver), someone on
this list provided the following script which is what "fixed" the issue at
the time by creating a new 70-persistent-net.rules file with the devices
enumerated in order. However, this no longer works now.

Don't specify GATEWAY in interface files where it isn't used. This
should be set on eth0 only.

OK, so you don't have a bridge interface. If you want to
