So after next reboot we may get different interface names.

Also /lib/udev/write_net_rules is unavailable. Hey Cecil, Here's the rpms we have on a rhel 6.5 server that actually does create the 70-persistent-net.rules file (looks like the same rpms): udev-147-2.51.el6.x86_64 Even when only one card is connected besides the onboard athereos (I disconnected the old Realtek). Udev uses matching information provided by sysfs with rules provided by the user to dynamically add the required device nodes. Additional info: 70-persistent-net.rules _is_ written if I rmmod a network driver and modprobe it back. Udev is the mechanism used to create and name /dev device nodes corresponding to the devices that are present in the system. Reboot. Stack Exchange network consists of 177 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share … I reinstalled udev, tryed to downgrade but still when I change the device name after 'start_udev' it duplicates with the old name in 70-persistent-net.rules file ;/.

Hello, I want to boot a computer from network by PXE, with an NFS filesystem as root fs, install a basic system on the local disk and then boot the computer from the disk. Actual results: 70-persistent-net.rules does not exist.

Network Udev rules are missing.

Expected results: 70-persistent-net.rules should have been created from scratch by udev after reboot. 请问 70-persistent-net.rules 文件里的mac地址是怎么来的,我这里有块万兆光口网卡在lspci下看到的mac是一样的。 [root@new-b3 ~]# lspci -D -n -v |egrep "0200|Serial" All of my own contents here (if not noted otherwise) are licensed under the Creative Commons Attribution-NonCommercial-ShareAlike 4.0 License.
