Beaglebone Blackでeth1の固定IP設定

Beaglebone Blackでeth1の固定IP設定

起動後、eth1インターフェイスに静的IPアドレスを設定する必要があります。ただし、起動時にデバイスは常に/etc/network/interfacesに設定されているIPアドレスとは異なるIPアドレスを持ちます。これはBeagle BoneのLinuxオペレーティングシステムです。

私のビーグルボーンでは、次のLinuxバージョンを使用しています。

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

ファイルは/etc/network/interfaces以下のようになります。

##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
    dns-nameservers 8.8.8.8

# Ethernet/RNDIS gadget (g_ether)

iface usb0 inet static
    address 192.168.7.2
    netmask 255.255.0.0
    network 192.168.7.0
    gateway 192.168.7.1

ifconfigの出力は次のとおりです
