Connect Pi-Zero via USB RNDIS Gadget to Ubuntu 17.04

Question

I'm trying to ssh to a Pi Zero via USB link. While this works as expected from my MacBook with OSX 10.10, I'm not able to ssh or ping the raspberry From a Linux Host over USB.

What I did:

On the MicroSD-card: Add "dtoverlay=dwc2" to config.txt

Add "modules-load=dwc2,g_ether" to cmdline.txt

insert a blank file called "ssh" in the same directory as config.txt and cmdline.txt

On the Macbook ssh [email protected]

This works. Then I shut down the zero, add again a file called "ssh" in the directory and connect it to my Ubuntu Machine.

On the Ubuntu 17.04 Desktop machine

ssh [email protected]

Error: Could not resolve hostname

ssh pi@raspberrypi

Error: Could not resolve hostname

Why doesn't the Ubuntu machine assign an IPv4 network address to the Raspberry Pi zero?

ping6 fe80:0000:3c1:11d6:f2aa:fe13

ping: fe80:0000:3c1:11d6:f2aa:fe13: Name or service not known

Thanks for any hints

Answering to myself: I found the answer now (actually I don't really know, why it works, but it works).

• Open Network Settings. If the Zero is connected and active, you'll find an entry for "USB Ethernet"

• Click the Settings-Button on the lower right.

• Go to the "IPv4" Tab and change "addresses" to "Link Local only"
• Go to the "IPv6" Tab and turn it "Off".

After a few seconds, the network will say "connected", and then you can ssh to the zero with "ssh [email protected]"

Still, the Pi doesn't have internet connection. A network bridge would be necessary for that.
