Which is so complex. According to the man page 'command --reload-rules'
does NOT change any device that has existing rules. So by that, if you
change a rule, tough luck. It is SUPPOSE to be automatic.
I have tried exporting the dev-db and looking for the mac info. But
have not succeeded yet.

All the instructions I have found for 70-persistent-net.rules call for
running:
start_udev
But it is not on ANY of my f20 systems, arm or intel. Something
changed. Most likely related to systemd stuff.
So any pointers would be appreciated, as I still don't have this
working.

famous last words.
So I want a 70-persistent-net.rules so I can specify the MAC
address to
the device name. Then in the ifcfg-xxxx I can change the
MACADDR to
what I want.
I got this working on my Redsleeve arm system, but now I need it
on my
F20 arm system.
So I have done a little searching on creating
70-persistent-net.rules,
and I come up with two commands:
udevadm trigger
udevadm trigger --action=add
I have run both and no 70-persistent-net.rules
help please...
As before, you need to create it yourself. I wrote a little script
that will do this, which you can see here:
https://alteeve.ca/w/Changing_Ethernet_Device_Names_in_EL7_and_Fedora_15%2B#Writing_The_udev_Rules_File
Thanks. I used your script to create my rules file:
# cat /etc/udev/rules.d/70-persistent-net.rules
# Added by 'write_udev' for detected device 'eth0'.
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:56:02:01:f3:b9", NAME="eth0"
And that looked good (right madaddr and device name). So built my
ifcfg-eth0:
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
BOOTPROTO=none
NM_CONTROLLED="no"
ONBOOT="yes"
TYPE="Ethernet"
NAME="System eth0"
MACADDR=02:67:15:00:01:78
MTU=1500
DNS1=208.83.67.188
GATEWAY="208.83.67.177"
IPADDR="208.83.67.178"
NETMASK="255.255.255.240"
HOSTNAME="miredo.htt-consult.com"
IPV6INIT="yes"
DNS2=2607:f4b8:3:3:9254:5400:0:188
Something is missing as after the change I restarted
network.services
and got IPv6 RA errors. So I rebooted and now no eth0 listed with
ifconfig (or ip addr show). So something is lacking. Almost like
udev
is not running at boot? How do I check this out?
I've not played with IPv6 yet, and on my system it "just worked". So
I'm not sure what to suggest. Is there a systemd udev target?
SOmething like this:
# systemctl list-unit-files --type=service|grep udev
dracut-pre-udev.service static
initrd-udevadm-cleanup-db.service static
systemd-udev-settle.service static
systemd-udev-trigger.service static
systemd-udevd.service static
I reported the inability to change network-interface names in
70-persistent-net.rules as a bug on centos 7.
http://bugs.centos.org/login_page.php , report number 0007472
I was told to set the two kernel parameters
net.ifnames=0 biosdevname=0
Where/how do you change these?
after that, still in centos 7, the kernel did not change the
network-interface names any more, but still I was not able to rename
them.
This may help also in fedora 20?
See SOLVED posts coming up. All working, but I am not renaming the
interface, I am changing the macaddr.
