armbian N1 開機固定MAC debian10

  GNU nano 3.2 /boot/uEnv.ini  

dtb_name=/dtb/meson-gxl-s905d-phicomm-n1.dtb

bootargs=root=LABEL=ROOT_EMMC rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend

ethaddr=42:b8:79:09:d8:ed

不過 有時候不管用。。。。

那就

nano /etc/network/interfaces

# Wired adapter #1
allow-hotplug eth0
no-auto-down eth0
iface eth0 inet dhcp
hwaddress ether FC:55:44:33:22:11
pre-up ifconfig eth0 hw ether FC:55:44:33:22:11
           

如果雙IP。。。。

設定參數： /sbin/sysctl net.ipv4.conf.eth0.promote_secondaries=1 (晉升輔助ip位址）

If this is enabled, and primary address of an interface gets deleted, an alias of the interface (secondary) will be upgraded to become primary.

The default is to purge all the secondaries when you delete the primary
設定重新開機後仍然生效：echo "net.ipv4.conf.eth0.promote_secondaries=1" >>/etc/sysctl.conf

ip addr del 192.168.198.97/24 dev eth0
