Assign Virtual IPs to your NIC

Edit file /etc/sysconfig/network-scripts/ifcfg-eth0.

DEVICE=eth0

BOOTPROTO=static

BROADCAST=192.168.0.255

HWADDR=00:00:00:00:00:00

IPADDR=192.168.10.2

NETMASK=255.255.255.0

NETWORK=192.168.10.0

ONBOOT=yes

TYPE=Ethernet

GATEWAY=192.168.10.1

 

Make a copy of this in the same directory naming the new file ifcfg-eth0:1

# cp ifcfg-eth0 ifcfg-eth0\:1

 

Modify /etc/sysconfig/network-scripts/ifcfg-eth0:1 file. Modification are in bold

DEVICE=eth0:1

BOOTPROTO=static

BROADCAST=192.168.0.255

HWADDR=00:00:00:00:00:00

IPADDR=192.168.10.101

NETMASK=255.255.255.0

NETWORK=192.168.10.0

ONBOOT=yes

TYPE=Ethernet

GATEWAY=192.168.10.1

# cp ifcfg-eth0\:1 /etc/sysconfig/networking/devices/

# cp ifcfg-eth0\:1 /etc/sysconfig/networking/profiles/default/

 

Now, bring up the new interface using the ifup script:

# ifup eth0\:1

Running ifconfig, the new interface should be listed. You can also check it by pinging:

# ping 192.168.10.101
