When I got my boards yesterday and after discarding my buildroot image, I attempted to set up network on my ubuntu image.
No luck in getting static ip working adding files to /etc/network/interfaces.d/
So I went to sleep and when I got up, I started trying out the examples on this thread.
I couldn’t get any of them working unmodified.
I couldn’t get static IP working.
I did get dynamic IP working for wan:
iface eth0 inet manual
iface lo inet loopback
iface wan inet dhcp
pre-up /sbin/ifconfig eth0 up
… If anyone succeeds in getting static ip working for all 3 interfaces, please post here (even if the thread gets old).
Note: I’m using the rootfs.tar.bz2 from ubuntu-16.04.3.zip with a 2GB board.
