ubuntu 20.04 / netplan / change mac address and static ip

I wasn't able to set together a virtual mac address and a static IP using netplan: either the mac address didn't change, or IP was not set.
I finally got the trick using a fake nic definition that matches the new virtual mac address I've set.

 

 network:
  renderer: networkd
  ethernets:
    ens160:
      match:
        macaddress: 00:0c:29:5a:69:00
      macaddress: 00:50:56:0c:de:a6
    ens160_2:
      match:
        macaddress: 00:50:56:0c:de:a6
      addresses: [ 139.99.5.72/32 ]
      nameservers:
        addresses: [ 8.8.8.8 ]
      routes:
      - to: 0.0.0.0/0
        via: 139.99.5.254
        on-link: true
    ens192:
      addresses: [192.168.103.14/24]
      #dhcp4: true
  version: 2

Connect the Xiaomi Yi Ants Cam to your Synology Surveillance Station

1) Ensure the current firmware of your cam allows you to see the steam without authentication. You can check this using vlc and connecting to rtsp://192.168.1.128:554/ch0_0.h264 If you are able to see the stream, you can go to the next point. Otherwise you have to downgrade the firmware of your cam : Simply place this file on the root of an SD card, insert the SD card in the cam and reset it (a reboot may be sufficient) 2) Create the following file on your synology using putty /volumeX/@appstore/SurveillanceStation/device_pack/camera_support/Xiaomi.conf with this content: [Xiaomi*Ants] api = custom resolution_h264 = 1280x720 default_resolution_h264 = 1280x720 fps_h264_640x480 = 5,10,15,20,25,30 fps_h264_1280x720 = 5,10,15,20,25,30 default_fps_h264_1280x720 = 10 default_image-quality = 5 h264 = rtsp mpeg4 = rtsp mjpeg = rtsp motion = h264,mpeg4,mjpeg motion_param = sensitivity,threshold rtsp_keepalive = none rtsp_protocol = auto,udp,tcp 3) In the surveillanc...
