큐비보드의 onBoard Ethernet이 죽었다..
왜 죽었는지 정확한 원인을 모르겠지만, LAN 케이블을 꽂아도 불이 안들어오고,
부팅시 eth0가 올라오지 않는다..ㅠㅠ
그래서 결국 USB Ethernet을 구매했다.(WIFI를 살까 하다가 비싸서 Pass..)
먼저 USB Ethernet을 꽂고 인식하는지 확인..

잘 인식되었다ㅋ
그리고 ifconfig -a 으로 전체 인터페이스를 확인한다.

eth0 는 onBoard의 죽은 인터페이스이고 eth1은 어디 가고 없다??
eth2 가 usb Ethernet으로 보이니 up 해준다.

root@cubieboard2:/# ifconfig eth2 up |
그럼 이제 ip를 dhcp으로 받아오자
|
1 |
root@cubieboard2:/# dhclient eth2 |
IP가 잘 받아와졌는지 확인해보자.

하지만 이렇게만 해두면 부팅때마다 설정해야 하므로 부팅시 올라오도록 설정한다.

고정 IP으로 할당했다.
재부팅 해서 확인해보면 잘 받아 오는 것을 볼수 있다.
굿~
