Activating MATLAB under fedora 20 - ETH0 is reported missing.

Hello,

It's just an upgrade to fedora 20...

but il use a lot of methods to rename ethernet device to eth0... (the same methods in fedora 15, 16, 17 and 18) but NOPE.

I got em1:, I used biosdevname=0, I removed biosdevname package, I change data and files in /etc/sysconfig/network-scripts...

Now I have enp1s0:

and MATLAB is not activated. *%#@!&%£## !!! grrrrrrrrr.

Does any body could help me, please !

Thanks a lot.

Bernard, from France.

PS. Any way, if I have to downgrade to fedora 19, I will do it, but tell me !!

The easiest way to restore the old way Kernel/modules/udev rename your ethernet interfaces is supplying these kernel parameters to Fedora 19:

    net.ifnames=0
    biosdevname=0

To do so follow this steps:

    Edit /etc/default/grub
    At the end of GRUB_CMDLINE_LINUX line append "net.ifnames=0 biosdevname=0"
    Save the file
    Type "grub2-mkconfig -o /boot/grub2/grub.cfg"
    Type "reboot"

If you didn't supply these parameters during the installation, you will probably need to adjust and/or rename interface files at /etc/sysconfig/network-scripts/ifcfg-*.

Up to Fedora 18, just biosdevname=0 was enough.

As an example, in a certain machine, in a exhaustive research, I got:

-No parameters: NIC identified as "enp5s2". -Parameter biosdevname=0: NIC identified as "enp5s2". -Parameter net.ifnames=0: NIC identified as "em1". -Parameter net.ifnames=0 AND biosdevname=0: NIC identified as "eth0".
