eth0 config

rename xxx to eth0

errors may occur:

Ubuntu networking restart | cannot find device 'eth0'

check eth0

$ dmesg | grep eth

[5.715564] e1000 0000:02:01.0 eth0: (PCI:66MHz:32-bit) 00:0c:29:7d:bf:43
[5.715573] e1000 0000:02:01.0 eth0: Intel(R) PRO/1000 Network Connection
[5.719709] e1000 0000:02:01.0 ens33: renamed from eth0

and we get ens33 renamed from eth0, we need to change it back to eth0.

solution

(1). edit grub and update

$ sudo vim /etc/default/grub

GRUB_CMDLINE_LINUX=""

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

$ sudo update-grub

(2) edit network interfaces

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.1.77
netmask 255.255.255.0
gateway 192.168.1.1

(3) reboot

sudo reboot now

(4) check eth0

$ sudo ifconfig

OK. Now we get eth0,wlan0 properly set.
