change eth0 and eth1 with udev rules
« on: April 05, 2018, 03:40:22 PM »
Hi,

is it correct that i can use /etc/udev/rules.d/70-persistent-net.rules to change eth0 to eth1 and eth1 to eth0 or which file is used under TC for doing this ?
1 + 2 = 6  cause  10 - 6 = 78 ;-) lol

Hi halma
You could try:
Code: [Select]
SUBSYSTEM=="net", ATTR{address}=="ab:cd:ef:12:34:56", NAME="eth0"
SUBSYSTEM=="net", ATTR{address}=="65:43:21:fe:dc:ba", NAME="eth1"
That was found here:
https://bbs.archlinux.org/viewtopic.php?id=140029

The  ATTR{address}==  refers to the network adapters  MAC  address.

Try ifrename as well, it's been mentioned here before.
The only barriers that can stop you are the ones you create yourself.

Hi halma
As is often the case there can be multiple ways of doing something under Linux. If you don't want to use  udev  you can try adding
this to your  /opt/bootsync.sh  file:
Code: [Select]
# Assign unused names to the network cards
nameif want_eth0 ab:cd:ef:12:34:56
nameif want_eth1 65:43:21:fe:dc:ba

# Assign the desired names to the network cards
nameif eth0 ab:cd:ef:12:34:56
nameif eth1 65:43:21:fe:dc:ba

If your  opt  directory is not persistent, run a backup and reboot. The  nameif  command is the  busybox  version of  renameif.

If you do try the  udev  way you probably need to ad this to your  /opt/bootsync.sh  file:
Code: [Select]
udevadm control --reload-rules
udevadm trigger
