"...Device eth0 has different MAC address than expected,.."
I had to setup 3 identical Fedora Core 4 systems for a custom application training session.
All 3 machines have identical hardware. So I got the first machine configured as per the requirements. Then I used "Ghost for Linux" to make an image of this PC on a ftp server. I used the "Ghost for Linux" boot CD to put the same image on the 2nd machine. Machines 1 and 2 are DHCP clients and they are working pretty much as expected. But ONLY on the 2nd machine, I keep getting this warning (on the console) when I reboot: Quote:
And it is being ignored. But I would like to fix this warning. How do I fix eth0 on the 2nd machine so that the inherited MAC address goes away and therefore the above warning goes away? |
On a Debian machine I would investigate the /etc/iftab file. I'm not sure if this is the same file on a FC machine, but it might point you in the right direction.

Thanks for the tip.
It helped me find the right file to edit: /etc/sysconfig/network-scripts/ifcfg-eth0 Just updated the HWADDR value and rebooted the system. Problem solved. |
Good to know, thanks!
|
thanks, just the ticket
had similar problem with RedHat RHEL5.4 on and old Toshiba laptop.
Edited the file and it worked. |
I have the same problem.
When I try to change MAC with the following commands: ifconfig eth0 down ifconfig eth0 hw ether aa:bb:cc:dd:ee ifconfig eth0 up after service network restart it gives me the error: Device eth0 has different MAC address than expected, ignoring. I also tried to update /etc/sysconfig/network-scripts/ifcfg-eth0, but after the restart nothing happens, the new MAC has no effect. Is there another way to do it? P.S. I am using Centos 6.4. |

If you have multiple NICs in your server then the HWADDR line is essential so that networking has a physical to "logical" mapping. You could also try Code:
ifconfig -a |

I fixed the error, Thanks!
I followed these steps: 1. type ifconfig -a to get Mac Address. 2. vi /etc/sys.../ifcfg-eth0 and replace HWADDR by the Mac Address I get by above step. |
