am try to create another network card as virtual eth0:1
but when i restart the server it want be appear i have to create it again what is the solution for this .

How did you create it?

Technically none of the Linux kernel settings except compiled-in ones are permanent, they get set by system init scripts and the like on boot.

am using this command ifconfig eth0:1 192.168.168.1.5 netmask 255.255.255.0
and i have read you have to create in config file for it.

From memory, not tested. Create an alias interface configuration file named "ifcfg-eth0:1" Put it in the same directory as your "ifcfg-eth0". It should have something like the following in it:

Code:

DEVICE=eth0:1
IPADDR=192.168.168.5    
ONBOOT=yes

i have create another file ifcfg-eth0:1 and then i change device= eth0:1 but am getting error to get new ipaddress.

Create a file named ifcfg-eth0:0 under /etc/sysconfig/network-scripts/ folder with the below sample contents

sample:
DEVICE=eth0:0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.1.99
NETMASK=255.255.255.0

restart your network service / reboot your machine...

am getting this error when try to up the first nic eth0
