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.

Thanks Nikolai,

In advance, have you got any url that might be of some help?

I'm searching for this right now.

In reply to Mauricio Silveira

... 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 ...

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

Hi,

I'm just updating this thread to post useful information.

I was unable to use ifrename to do the trick ...

I have upgraded the server to slackware 12, since the disk mirroring was incomplete when slackware 12 was released, so I decided to rebuild the raid array and install slackware 12 on it :)

Tuning the file "/etc/udev/rules.d/75-network-devices.rules" as needed seems to solve the problem. I encourage everyone who uses slackware as you system to upgrade to v12 :)

Although I think samba 3.0.25b needs some "monitoring", got some strange behavior from this version, downgrading brought everything back in place.

Thanks for all your help,

Mauricio

Hi,

I've this problems too, but I was using initrd to load many modules to work with AoE, I can't change the interface using udev :(, I use the solution was rename the interfaces using ip command intro the initrd after up the interfaces.

Thanks in advance,
