fedora 18 : change Ethernet device name from pXXpX to ethX

[root@f18 ~]# cat /etc/fedora-release Fedora release 18 (Spherical Cow) [root@f18 ~]# uname -ri 3.9.0-0.rc5.git1.1.vanilla.mainline.knurd.1.fc18.x86_64 x86_64

My laptop has one physical NIC and the device name is p10p1.

Here’s an explanation of how to change the device name from p10p1 to eth0.

- before change the device name

# biosdevname -i p10p1 -d BIOS device: p10p1 Kernel name: p10p1 Permanent MAC: 78:E7:D1:xx:xx:xx Assigned MAC : 78:E7:D1:xx:xx:xx ifIndex: 2 Driver: r8169 Driver version: 2.3LK-NAPI Firmware version: rtl_nic/rtl8168d-2.fw Bus Info: 0000:02:00.0 PCI name      : 0000:02:00.0 PCI Slot      : 10 Index in slot: 1

There is no “70-net-persistent.rules” file under “/etc/udev/rules.d”

# ls /etc/udev/rules.d/* /etc/udev/rules.d/60-sysprof.rules #

# pwd /etc/sysconfig/network-scripts # cat ifcfg-p10p1 TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no NAME=p10p1 UUID=2b9e9659-417d-4c35-a6b6-f33e8acf8ac1 ONBOOT=yes HWADDR=78:E7:D1:xx:xx:xx IPADDR0=192.168.11.100 PREFIX0=24 GATEWAY0=192.168.11.1 DNS1=127.0.0.1 IPV6_PEERDNS=yes IPV6_PEERROUTES=yes

- change the device name to eth0 from p10p1

edit /etc/default/grub

add “biosdevname=0”

# cat /etc/default/grub GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)" GRUB_DEFAULT=saved GRUB_CMDLINE_LINUX="biosdevname=0 rd.md=0 rd.lvm=0 rd.dm=0 vconsole.keymap=jp106 $([ -x /usr/sbin/rhcrashkernel-param ] && /usr/sbin/rhcrashkernel-param || :) rd.luks=0 rhgb quiet" GRUB_DISABLE_RECOVERY="true" GRUB_THEME="/boot/grub2/themes/system/theme.txt"

update grub2 config

# grub2-mkconfig > /boot/grub2/grub.cfg

I assigned an static IP.

create  ifcfg-eth0 file unnder /etc/sysconfig/network-scripts directory.

# cp ifcfg-p10p1 ifcfg-eth0

edit ifcfg-eth0

change the device name “NAME” to eth0 from p10p1

# diff ifcfg-p10p1 ifcfg-eth0 9c9 < NAME=p10p1 --- > NAME=eth0 # cat /etc/sysconfig/network-scripts/ifcfg-eth0 TYPE=Ethernet BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no NAME=eth0 UUID=2b9e9659-417d-4c35-a6b6-f33e8acf8ac1 ONBOOT=yes HWADDR=78:E7:D1:xx:xx:xx IPADDR0=192.168.11.100 PREFIX0=24 GATEWAY0=192.168.11.1 DNS1=127.0.0.1 IPV6_PEERDNS=yes IPV6_PEERROUTES=yes #

reboot the OS.

after rebooting the OS.

the device name has been changed to eth0.

# ifconfig eth0 | grep "inet"        inet 192.168.11.100  netmask 255.255.255.0  broadcast 192.168.11.255 # biosdevname -i eth0 -d BIOS device: p10p1 Kernel name: eth0 Permanent MAC: 78:E7:D1:xx:xx:xx Assigned MAC : 78:E7:D1:xx:xx:xx ifIndex: 2 Driver: r8169 Driver version: 2.3LK-NAPI Firmware version: rtl_nic/rtl8168d-2.fw Bus Info: 0000:02:00.0 PCI name      : 0000:02:00.0 PCI Slot      : 10 Index in slot: 1
