I have just installed 6.3 on a machine that was previously running
5.8. Under 5.8 eth0 was eth0. Now with 6.3 /sbin/ifconfig gives me lo,
wlan0 and p4p1 (instead of eth0). I would like to make the ethernet a
static IP as I intend to for this to be machine used on my LAN only.
However, when I do /usr/sbin/setup -> Network Configuration the device
is not listed. Can anyone tell me why this is happening and how I can
fix it. Or if not how I can set a static and persistent IP address for
the ethernet?
Thanks,
Richard

Well......
I tend to agree with the slashdot commentator who called it overcomplicated and unnecessary. It's another idea from
Fedora, the theory, IIRC, was that this way, devices would always have the same name, whereas under the
method that has been used device names could change on a reboot. (Haven't experienced that myself, but
dunno).
If you google Fedora biosdevname you'll come across various explanations. To change it back once the thing's been installed, I've always
done it by first rpm -e biosdevname, then editing /etc/sysconfig/network-scripts/ifcfg-whatever, changing the device
name in there to eth0, changing the name of the file, e.g, ifcfg-p4p1 to ifcfg-eth0 and
restarting. I haven't gotten it working by just restarting networking, but at any rate, if you
know you don't want it during installation, you can add biosdevname=0 to the command line.

Yup. The difference between that, and sticking the MAC address into a
simple, existing config file is, oh, that's right, it's k3wl.

I have. Putting the MAC address into ifcfg-eth? fixes it.
<method elided>
EXCEPT that in 6.x, you really need to edit
/etc/udev/rules.d/70-persistant-net.rules, too, or take the MAC out of
ifcfg-eth?, since it needs to be in 70-blahblah.

Strange device labeling in 6.3
If it's as simple as sticking the MAC address into the ifcfg-eth file,
I can live with that. But only ifcfg script that exits in
/etc/sysconfig/network-scripts/ is ifcfg-lo
I have no idea what k3wl is.
Thanks for the replies.

There should be *something*. Sounds like something's missing in the

The difference _should_ be that you could ship a pre-installed disk to
a remote site where it meets up with an freshly shipped server chassis
and the on-site person racking it up can know which NIC to put which
cable in and have it come up working. But, I think that's only
possible with Dells.

That assumes that you know the MAC address at the time you'd like to
configure the image. That's rare for me. As are on-site people fluent
in linux.

I installed off the live CD. I will try a 6.3 net install and see what changes.

try editing
/etc/udev/rules.d/70-persistent-net.rules
change p4p1 to eth0 as the value for NAME
reboot
hope this helps

this has happened to me a couple of times
worst case:
eth0 = unused realtek onboard
eth1 = intel nic used for lan1
eth2 = intel nic used for lan2
eth3 = intel nic used for wan

Alternatively, with the biosdevname, you can pin the interface name to
the pci(e) slot. That way its a trivial exercise to get 'remote hands'
to swap out a dead nic -- no need to fiddle with the mac address.
