Ethernet devide enumeration problems

Hi all,

I'm here asking for solutions for the Damned "Ethernet device 
enumeration" problem!

I have a P5b Mobo for my office server, it has 2 integrated NICs, but 
the order for eth0/eth1 changes at each boot! It's getting me mad!

I'm using slackware 11.0, kernel 2.6.21.3.

I know Suse and RHEL has a solution, but it integrates too many things 
to get it working under slackware.

Any "easy"(not with so many dependencies) way?

Thanks,

Mauricio

Use udev with rules for keeping the ethernet interfaces consistant.

Re: Ethernet devide enumeration problems

Hi Mauricio,

Just read the following file:

/etc/udev/rules.d/network-devices.rules

and you should get an idea of what to do with it.
If not, send another e-mail to the list.

Cheers,
George Iosif

Re: Ethernet devide enumeration problems

... ciao:

    as a preface:

    i've read suggestions about using udev and associated magic
toward a solution.  i am not convinced that the way to go.

: on "6-26-2007" "Mauricio Silveira" writ:
: P5b Mobo for my office server, it has 2 integrated NICs
: the order for eth0/eth1 changes at each boot!

    as the nics integrated into the motherboard, reference to them must
exist withing the bios.  by implication, this well prior to a kernel
loading, and executing modules for udev (hotswap) hardware.

    the approach i would attempt, is to assign a static irq and addr to
each device, within the bios, and pass that information to the kernel via
tbe bootloader.  just a thought ...

    if i have to , i guess ...

Hadn't heard of ifrename before.  That's really useful to know about
(although bizarrely it is part of the wireless-tools package under
fedora/red hat/centos).

Cheers
