Cloning MAC Addresses Revision as of Sunday, 20 December 2015 at 19:56 UTC
On RHEL-based systems
If your interface is eth0, edit
/etc/sysconfig/network-scripts/ifcfg-eth0. If you see a HWADDR
param, comment it out and add MACADDR=xx:xx:xx:xx:xx:xx. Here’s a
sample:
DEVICE=eth0
BOOTPROTO=dhcp
#HWADDR=00:12:79:A0:59:DE
MACADDR=00:12:79:A0:59:F4
ONBOOT=yes
# On CentOS 6
BOOTPROTO="dhcp"
Then restart the network service for this to take effect:
service network restart
On BSD-based systems
If your interface is igb0, add a file called /etc/start_if.igb0 to
specify the cloned MAC:
ifconfig igb0 ether 00:12:79:45:89:df
Then reboot your server.
