[Linux] Ubuntu 16.04 LTS Ethernet Interface 이름 바꾸기

"/etc/default/grub" 를 에디터로 아래 내용을 변경한다.

 

#GRUB_CMDLINE_LINUX=""

 

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

 

 

그리고 반드시 업데이를 해줘야 함.

$ sudo update-grub

 

시스템을 재시작 한다.

$ sudo reboot

 

$ ifconfig
eth0      Link encap:Ethernet  HWaddr 00:30:64:18:4b:6b
          inet addr:192.168.1.63  Bcast:192.168.1.255  Mask:255.255.255.0

이제 eth0를 내가 원하는 이름으로 다시 변경 하도록 하자.

 

아래 경로에 "70-persistent-net.rules" 파일을 생성한다.

 $ sudo vi /etc/udev/rules.d/70-persistent-net.rules

 

아래 내용을 추가하고 저장 한다.

# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.

# You can modify it, as long as you keep each rule on a single
