It does if you build one into the kernel.

Because you no longer have eth0 and eth1 which may be one or the other NIC depending on module load order or in which order the kernel discovers the NICs. Look at my example rules again: Each interface is identified by its MAC address and given a unique name. Since the MAC addresses never change, the names will also stay the same, regardless of module loading order or interface discovery order. HTH...

True, but, depending on how you interpret the original question, it cold also mean that the wrong driver claiming the card means the interface doesn't come up. It all depends on how you interpret "this doesn't work", which isn't the most useful of descriptions. If it is simply a naming problem, then udev persistent names are the best solution, but I'm not sure that's the problem. Perhaps the OP could clarify what is going wrong. -- Neil Bothwick After a few years in space, even Worf started to look good... signature.asc Description: PGP signature

And, again, we're talking about a firewall. Giving meaningfull names to the NICs (for example: intranet, extranet) could also make the fw rules more readable. Bye...

He may have a reason for using modules. Which one? Usually a firewall usually needs the NICs right after booting, so using modules doesn't make sense. Bye...

I thought that,but reading the question again, I don't think the problem is naming, but the wrong driver claiming the card. I think the solution may be to set rc_hotplug="!net.*" in /etc/conf.d/rc then the modules will load in the order given in autoload. Or check the modules' documentation for options that will control which cards they attach themselves to, which would be a cleaner solution. -- Neil Bothwick File not found. Should I fake it?

Could he not just build the modules into the kernel and then not have to
worry about the loading at all? Heck, the only module I use is nvidia
but it is not a "in kernel" option.
Just a though. He may have a reason for using modules.

You can let udev assign persistant names to your network interfaces.
# cat /etc/udev/rules.d/10-local.rules
KERNEL=="eth*", ATTRS{address}=="00:1c:25:1a:ee:0c", NAME="lan0"
KERNEL=="wlan*", ATTRS{address}=="00:1e:4c:37:39:41", NAME="wlan0"
Then create the appropriate symlinks for them in /etc/init.d.

[gentoo-user] How to nail the order of modules loaded
Hi, I have a box that serves as a firewall and thus has different NICs. However when booting I run into a problem: One of the NICs needs the de4x5 driver another the tulip one. Udev loads tulip first, which then tries to claim the card the needs de4x5 but this does not work. So I have to manually set things straight after- wards. Is there a way to force it to first load de4x5 and then tulip? /etc/modules.autoload.d seems to be used too late. Regards, Konstantin -- Dipl-Inf. Konstantin Agouros aka Elwood Blues.
