I have headless rpi3. I have problem when I connect RPi ethernet directly to PC. Network is going down after a while. My /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

auto eth0:0
iface eth0:0 inet static

I am able to use both eth0 and eth0:0 when I connect it to my router with:> eth0>eth0.0.

After that when I connect RPi to my PC directly, I can reach RPi over for a while than it is gone. I dont know why. Why it is like that? How can I fix it?


If you REALLY want an Answer - you CAN'T "fix it" because this is how virtual network interfaces work.

If you read the documentation you will discover that you can only define a virtual network interfaces if the interface exists, which yours WON'T if not connected to a DHCP server.

There is also NO POINT in attempting to define a netmask (or CIDR notation) on a virtual network interface.
