I have been desperately trying to set up a pi Zero as a dongle computer, in order to ultimately try to install poison tap on it. There are quite numerous howtos on the web, like the one you can hit on adafruit. I managed to get the Zero booting up with Jessie, I set up the config files to make it act as ans RNDIS adapter. Now, when it's booted I can see from the computer on which the Zero was plugged in
Bus 003 Device 091: ID 0525:a4a2 Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget

*** it has an IP assigned, a different MAC address, but the manufacturer is one of the Zero manufacturers ... and it comes in when I plug the Zero in and goes away when I plug it out ...
I have tried to ssh on this address, but I am constantly denied access :
firstname.lastname@example.org's password: Permission denied, please try again.
... I am willing to take any suggestion into consideration, thanks in advance for your time
