HWADDR=00:0C:29:25:96:A3

IPADDR=192.168.0.2

NETMASK=255.255.255.0

NETWORK=192.168.0.0

>

GATEWAY=192.168.0.1

Save exit, and then copy an ifcfg-eth0, such as:

Cp ifcfg-eth0 ifcfg-eth2

Use the vi command to edit the ifcfg-eth2, such as: note: the device is still eth0.

DEVICE=eth0

BROADCAST=192.168.0.255

HWADDR=00:0C:29:25:96:A3

IPADDR=192.168.0.3
