Hi, I was wondering how I swap the interface names given to my ethernet card. I have two ethernet devices (one inbuilt on motherboard, other PCI card). And I want my onboard ethernet to be assigned eth0, and the card eth1, but it happens the other way round. How do I swap them round or cause them to be assigned the correct name

Thanks in advance, Buck

I believe the kernel assigns the names as it finds them. Since one is onboard and you can't move it down a few slots below the other, you are stuck with this. Unless there is a way to alias 0 to 1 and 1 to 0, but I would imagine that would make more trouble for you.

aah, ok. I'll just live with it

pull pci card out of its socket and, and turn your onboard card off in bios, then boot your system, it should remove the cards from hardware..

put onboard device on in bios, let your system detect the card as eth0, after put your pci card in and let it assign to eth1.

just another simple solution...

May be able to put card in another pci slot and it might get detected before the other.
Any reason other than order you perfer this?

I just prefere eth0 to be my LAN, and I found that if I load the driver as a module (for the pci card) and compile the driver for the onboard ethernet controller directly into the kernel, then they get assigned properly.

Also, do I need to have the networks on each ethernet interface using different submasks. IE I have a DSL router (proper all in one router, just set DMZ to IP of the server (the computer in question), and the server is plugged in on eth1 to the router (for internet access) and eth0 to the rest of the network, to make sure packets go in the right direction do I need to have eth1 on 255.255.0.0 and my LAN 255.255.255.0 or can they both be 255.255.255.0.

Sorry if thats a bit confusing, Buck

They both can be 255.255.255.0 but I would make one 192.168.1.0/24 and the other 192.168.2.0/24. Then using ipmasquerading to allow traffic from eth1 to eth0. Is this what you want to accomplish?

hello

i'm not sure about gentoo.

but on debian you can use a file called "/etc/mactab" to assign the name per mac address.

i also think you need to run "nameif" to make this work...

that said maybe you can do something with udev.
