Can anyone out there explain to me how to multi home a nic? I hate to say it but I'm a windows guy forced to learn Unix. The issue I currently have is I can't changed the ip on eth0, but in order to make it pingable by other servers I need to multi home the nic with a totally seperate Ip. Any help would be greatly appreciated.
Hi,
You didn't tell us what unix are you talking about, but by the interface name ( eth ), i'm guessing Linux...
It's easy to create aliases ( multi-home ) to a single nic, you just have to configure the interface as you did the original one, but it's name will be eth0:n, where n is a number for the alias... for example:
ifconfig eth0:1 plumb - add the interface
ifconfig eth0:1 192.168.0.1 up - configures the interface with an IP address of 192.168.0.1
Maybe you have some way to do it automatically without having to write the commands... try to look at your linux distribution documentation.
