ifconfig -a 명령어를 통해 이더넷 이름을 확인합니다.

 

root@latch:~# cd /etc/netplan

기존(/etc/network의 interfaces 파일 수정) 네트워크 설정이 /etc/netplan(17버전 이상)으로 변경되었습니다.

 

2. 00-installer-config.yaml 수정

root@latch:~# vi 00-installer-config.yaml

# This is the network config written by 'subiquity'
network:
  ethernets:
        ens160:
                dhcp6: no
                addresses: [192.168.0.100/24]
                gateway4: 192.168.0.1

3. netplan 적용 및 확인

root@latch:/etc/netplan# sudo netplan apply
root@latch:/etc/netplan# hostname -I
