How do i configure multiple IP addresses to one NIC? I also need it to remember the config after reboot. Thanks for the help!

Hi,

Tell us about the distro that you are using,

In Redhat, you can create a virtual interface by creating a file named ifcfg-[iface name]:[number] in folder /etc/sysconfig/network-scripts/. for example to create a virtual interface for eth0, create a file called ifcfg-eth0:0 under the above folder.

All necessary parameters can be modified inside this file, for example:

DEVICE=eth0:0
ONBOOT=yes
BOOTPROTO=none
IPADDR=192.168.10.21
NETMASK=255.255.255.0
TYPE=Ethernet

Remember to restart the network using service network restart.

Regards

I"m using CentOS 4.5. I'll give that a try. I used ifconfig to assign the IP's to a virual interface. However i wasn't sure that would stick if the machine went down for whatever reason.
