Prevent firewire as eth0

Kocil · 11-24-2006, 11:45 PM

Dear all.

I'm using Slack 11 on a notebook.
The notebook has firewire (eth1394) and a nic (sky2).
My problem is, the eth1394 is always configured as eth0
and sky2 as eth1.

I simply want the sky2 to be the eth0,
while the eth1394 as something else (eth1, or fwlan0).

I have read a solution using udev rule,
http://www.linuxquestions.org/questi...d.php?t=317854
but this one need us to detect the MAC address of the sky2 first.

Is there any simpler way ?
I tried some triks but no success yet, e.g:
1. put static alias in /etc/modules.conf

Code:

alias eth0 sky2
alias eth1 eth1394

2. Put this udev rules

Code:

KERNEL="eth1394", NAME="fwlan0"

Please help, thanks.

What's wrong with using the MAC address? A simple "ifconfig" will tell you (it's the part after "HWaddr").

I'm a distro developer (Vector Linux to be exact).
I want a global configuration that works on every computer,
not just a particular notebook.
As you may have known, the installation scripts in slack and also VL,
always configure eth0 as the primary network.
I don't want to mess up those scripts, just for this silly thing.

By the way,
I wonder, what is the rationale to give eth0 name for the firewire.
We know that eth means ethernet, doesn't it ?
Firewire is not ethernet, for sure.

If we accept wlan* for wireless network devices,
why not using, for example, fwlan* for the firewire devices ?

Thanks for responding.

Are you using a 2.6 kernel by any chance? Then try using /etc/modprobe.conf instead.

On this, did you read read this doc? I don't have a firewire card but udevinfo should help you to find some persistent criteria to use. Pay attention not to mix and match criteria from different sections.

Shouldn't this be

Code:

KERNEL=="eth1394", NAME="fwlan0"

?

Thanks for the udev howto link and the == corrections.
I think we are getting closer ...
Here is the output of udevinfo

Code:

Looking at device /class/net/eth0
  KERNEL=="eth0"
  SUBSYSTEM=="net"
  ...

Looking at device '/devices/pci0000:00/0000:00:1e.0/0000:06:04.2/fw-host0':
  ID=="fw-host0"
  BUS=="ieee1394"
  DRIVER==""
  ...

I tried the following rules, but they don't work.

Code:

SUBSYSTEM=="ieee1394", NAME="fw/%k"

Code:

BUS=="ieee1394", NAME="fw/%k"

Thanks for helping me thinkering.

Hi,
My problem was that my wireless card (Cisco Aironet 350) was always assigned eth0 and the 3c59x was always assigned eth1. My default routing always preferred eth0, and the is not the way I wanted it...

The File:
/etc/udev/rules.d/network-devices.rules
has the devices that Slack identified, and there are some instructions on
how to uncomment and modify them to force the eth0 and eth1 swap...
I changed:

Quote:

#KERNEL=="wifi?", SYSFS{address}=="00:07:0e:b8:f2:99", NAME="wifi0"
#KERNEL=="eth?", SYSFS{address}=="00:07:0e:b8:f2:99", NAME="eth0"
#KERNEL=="eth?", SYSFS{address}=="00:04:75:50:55:ee", NAME="eth1"

to this:

Quote:

#KERNEL=="wifi?", SYSFS{address}=="00:07:0e:b8:f2:99", NAME="wifi0"
KERNEL=="eth?", SYSFS{address}=="00:07:0e:b8:f2:99", NAME="eth1"
KERNEL=="eth?", SYSFS{address}=="00:04:75:50:55:ee", NAME="eth0"

I am running Slackware 11.0 and 2.6.17.13 kernel.

Also, when configuring Kismet I had to use 'cisco_wifix,eth0:wifi0' ,this is how it still appears for that program. (/proc/driver/aironet/eth0/)

Hope this helps. -CD-
