I Procedures may differ depending on your Linux OS or the definition file 
on the client system. Use the following information as reference. Ask the 
system administrator to change the definition file.
Ê After replacing a network controller or the system board, switch on and boot 
the server as described in section "Switching on the server" on page 67.
kudzu, the hardware configuration tool for Red Hat Linux, will launch at boot 
and detect the new and / or changed hardware on your system.
I kudzu may not launch at boot depending on the client’s environment.
Ê Select Keep Configuration and Ignore to complete the boot process.
Ê Use the vi text editor to specify the MAC address in the HWADDR section of 
the ifcfg-eth<x> file:
I The MAC address can be found on the type label attached to the 
system board or network controller.
Example:
In order to modify the definition file for network controller 1, enter the 
following command:
# vi /etc/sysconfig/network-scripts/ifcfg-eth1
In vi, specify the new MAC address as follows:
HWADDR=xx:xx:xx:xx:xx:xx
Ê Save and close the definition file.
Ê For the changes to take effect, you need to reboot the network by entering 
the following command:
# service network restart
I If the system board or network controller offers multiple LAN ports, it is 
necessary to update the remaining ifcfg-eth<x> definition files 
accordingly.
Ê Update the NIC configuration file to reflect the new card sequence and MAC 
address.
