Description of problem:
I have a Compal ACL10 laptop with built in Realtek 8139 ethernet and a Gemtek
Prism 2.5 wavelan PCI card (driver orinoco_pci). By default, kudzu maps both
devices to be "eth0", and only by manually editing modules.conf (adding an
"alias eth1 orinoco_pci" line) can I separate the two.
This is the output after editing the modules.conf file - not that it now thinks
it is "eth2" for some vaguely frightening reason; it is mapped to be eth1 in
modules.conf (and is working as such as I write).
# kudzu -p -c NETWORK
desc: "Harris Semiconductor|Prism 2.5 Wavelan chipset"
Version-Release number of selected component (if applicable):
Steps to Reproduce:
It just happens by default for me.
Actual Results: Mapped to the same device.
Expected Results: Mapped to different devices.
The description says it all, really.
Please try the kudzu-22.214.171.124-1 packages at:
These may resolve some of your issues.
Same problem on Thinkpad T23.
Fixing /etc/modules.conf doesn't fix it if you want to use redhat-
config-network, which runs kudzu -p.
When I compile both the wired and wireless as modules, I see that the
wireless is probed as eth0 at boot time, then the wired is probed as
eth1, then (both are unloaded, I assume) then the wired is probed as
eth0. In other words, if only one module is loaded, it becomes eth0.
I'll attach the dmesg output.
Maybe that confuses kudzu? Does it probe one device at a time?
I'm already using 1.1.36-1.
Created attachment 97824 [details]
my dmesg when both are compiled as modules
Also, when I compile both into the kernel (the e100 and the
orinoco_pci, that is), kudzu will still probe both on eth0.
If I remove my /etc/sysconfig/hwconf file (and all ifcfg-* files
in /etc/sysconfig/network-script, and everything
in /etc/sysconfig/networking) and reboot, kudzu will say that a
Prism2 card was removed (how the hell does it know that without a
hwconf? It should have no memory whatsoever). When I say, okay,
keep configuration it tells that me that a Prism2 card was added.
When I say "ignore" it creates an entry for eth2 in hwconf.
Obviously "keep configuration" and "ignore" don't do what they say
they do. Where, btw, does kudzu keep track of whether the user asked
it to ignore something? There doesn't seem to be field in hwconf.
Does the patch in #119655 help? I had the same problem - since fixing
the problem I found & reported there & retesting w/ my Orinoco card,
it looks to have gone away.
I'm having a similar problem with my Sony Vaio PCG-SRX77P, but since
both wired and wireless are built into this system, I can't simply
remove a card to get it to work right.
There are also problems with the insistence by kudzu network setups
of storing the MAC address in the /etc/sysconfig/network-
scripts/ifcfg-eth* files. This makes swapping out PC cards
particularly adventuresome, since the old MAC address doesn't
properly get flushed when you cnage devices or re-arrange which eth*
device is which and makes it refuse to even shut down the previously

This should be resolved as of FC4.
