Hi,

Nanopi R1 -  Kernel and Armbian version: 4.19.62-sunxi #5.92

 

I have the following problem:

If I put the ethernet cable on the interface, and then turn on the nano pi, the interface receives a valid ip.

But the problem is, if I start nanopi without the cable connected, and I connect after system boot, the interface does not receive ip configuration.

Configs and logs:

/etc/network/interfaces:

source /etc/network/interfaces.d/*

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
        address 10.100.3.1
        netmask 255.255.255.0
        gateway 10.100.3.1

auto lo
iface lo inet loopback

up command iptables-restore < /scripts/iptables

Your firmware is WAY outdated. Resources of Armbian are limited and we can only cover the most recent version of Armbian which is 22.02 atm.
