Hi,
I have x86 system and have used clonezilla to clone the entire hardisk of system A and restored it on another x86 system, system B. After the cloning process, i notice that the MAC address of the system B in the /etc/sysconfig/network-scripts/ifcfg-eth0 is changed and is having the MAC address of system A.
The interesting part is that if i do an ifconfig from the bash prompt, the MAC address of the system B is correctly displayed, but in ifcfg-eth0 script it is different. I had disabled kudzu, since i was always getting eth1 activated on System B, even though i had used eth0 on system A. eth0.bak was getting created instead on system B. Disabling kudzu resolved it.
My question is that how could i get the same MAC address for system B from ifconfig and in /etc/sysconfig/network-scripts/ifcfg-eth0. Is there any script to do it ?

The MAC address shown in the /etc/sysconfig/network/ifcfg-ethX files is just the address of what was detected at the time of installation. This is done to make sure the configuration is applied to the correct NIC. It does not auto-generate every time you reboot the system.
You will need to manually change that to the MAC address displayed by ifconfig, and add that to the list of things you need to update after cloning a system.

Or depending on your requirements just drop hwaddr from ifcfg so it applies to the detected adaptor regardless of MAC
