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:
[root at fsdsigns2 ~]# dmesg | grep eth
forcedeth.c: Reverse Engineered nForce ethernet driver. Version 0.60.

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.

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

KVM: bridge configuration for static IP address
I need to allocate public IP address to two guest os.
I have only 2 network card Interface on server. say eth0 and eth1.
I set eth1 a public IP address. so it should in

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.

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.

CentOS 5.0 ifcfg-eth0 gets renamed on boot
Hello,
I created a CentOS 5.0 x86_64 guest under Debian Etch with Xen 3.0.3 and it
boots fine except for one re-occuring problem - whenever it boots the
/etc/sysconfig/network-scripts/ifcfg-eth0 script gets renamed to .bak and
doesn''t configure the ethernet device.
Here is the content of this file:
TYPE=Ethernet
DEVICE=eth0

Forcing ifcfg-eth0 to use the same nic in multi nic machine
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

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.

How Do I ...
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

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
alias eth1 e1000e
alias eth2 e1000e

Kickstart with multiple eth devices
Here is my script for post install if you want to try it.
In order for the shuffling to not occur you do need to create the udev
rules file somehow. I am not sure how mangled this will be in email but
it is worth a try. It should run OK with nothing else. I have a better
version in the works but the enhancements are mainly useful for Fedora
19-21.

Using Puppet to swap eth0 and eth1
I''ve been using Puppet now for a month or so and I''ve come to a
problem that may warrant an additional Puppet metaparameter. I''m
advocating the addition of a metaparameter called "preaction" (or
something like that), which will perform some arbitrary action before
the resource is modified. There may be a way to do this within
Puppet already (with some

Kickstart with multiple eth devices
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

Detecting second network interface
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?

setting up 3 network cards
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.

Simple IP Question
I have a server located remotely running CentOS 5.x. I need to have
two IP's on the same interface. So I have this:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=none
BROADCAST=69.x.x.199
HWADDR=00:x:x:x:c6:10
IPADDR=69.x.x.194
NETMASK=255.255.255.248
NETWORK=69.x.x.192
ONBOOT=yes
GATEWAY=69.x.x.193

IP range
Hi all
Can someone explain me this:
ifcfg-eth0-range1:
ONBOOT="yes"
IPADDR_START="192.168.1.48"
IPADDR_END="192.168.1.55"
CLONENUM_START="1"
Why Bcast is 192.168.1.51 and why Mask is 255.255.255.252 ?
OS: Centos 6.3/64bit
Thanks

Mixed dom0/domU usage?
Hi,
I'm wondering about the impact of using both dom0 and domU's on a server at
the same time. I'm worried about the performance impact of running a Mysql
server in a domU and now I'm thinking about moving the Mysql part of a LAMP
setup into dom0 and running a few Apache guests as domUs. Since the Apaches
will serve mostly from an NFS share they won't have much impact on
