Beaglebone Black에서 eth1에 대한 고정 IP 설정

시작 후 eth1 인터페이스에 고정 IP 주소를 설정해야 합니다. 그러나 부팅 시 장치는 항상 /etc/network/interfaces에 구성된 IP 주소와 다른 IP 주소를 갖습니다. 이것은 Beagle Bone의 Linux 운영 체제입니다.

내 비글본에서 다음 Linux 버전을 사용하고 있습니다.

root@beaglebone:/etc/network# cat /proc/version
Linux version 4.4.54-ti-r93 (root@a4-imx6q-wandboard-2gb) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Fri Mar 17 13:08:22 UTC 2017

파일은 /etc/network/interfaces아래와 같습니다.

##connman: WiFi
#
#connmanctl
#connmanctl> tether wifi off
#connmanctl> enable wifi
#connmanctl> scan wifi
#connmanctl> services
#connmanctl> agent on
#connmanctl> connect wifi_*_managed_psk
#connmanctl> quit

auto eth1
iface eth1 inet static
    address 192.168.3.10
    netmask 255.255.255.0
    network 192.168.3.0
    gateway 192.168.3.1

    netmask 255.255.0.0
    network 192.168.7.0
    gateway 192.168.7.1

ifconfig 출력은 다음과 같습니다
