Hi,
I'm currently experimenting with CentOS 7 in order to get a grasp of
everything that's new.
After having read the FAQ entry on network interface names, I decided to
revert to the tradictional interface naming scheme by adding the
relevant kernel options to the bootloader. This went well, I have now
two interfaces names 'eth0' and 'eth1' as expected.
In my office I have another server with two network interface cards,
running Slackware64 14.1. On a stock Slackware installation, as soon as
there is more than one NIC, the system creates a file
/etc/udev/rules.d/70-persistent-net.rules, which looks like this:
# PCI device 0x8086:/sys/devices/pci0000:00/0000:00:02.0/0000:02:00.0
(e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="2c:27:d7:15:54:a1", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# PCI device 0x8086:/sys/devices/pci0000:00/0000:00:04.0/0000:03:00.0
(e1000e)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="00:22:64:8a:4c:c2", ATTR{dev_id}=="0x0",
ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
Usually I have a 50 % chance of getting the network interface right
(well, according to Murphy, I have more like a 100 % chance of getting
it wrong the first time :oD). In that case, I simple edit the
70-persistent-net.rules file, permutate the "eth0" and "eth1" entries
and then reboot.
How would I go about that under CentOS with traditional interface names?
The 70-persistent-net.rules file doesn't exist. Do I have to create it
from scratch?
Cheers,
Niki Kovacs
