armbian N1 开机固定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
不过 有时候不管用。。。。
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
如果一个网卡有多个IP，那么还需要设置下面的参数。（实际上管它几个IP，都设上）
设置参数： /sbin/sysctl net.ipv4.conf.eth0.promote_secondaries=1
此参数的作用为：晋升辅助ip地址，解释如下
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
设置重启后仍然生效：echo “net.ipv4.conf.eth0.promote_secondaries=1” >>/etc/sysctl.conf
ip addr del 192.168.198.97/24 dev eth0
