automatic ssh connection to device fails

[Zoltan Balogh]

After a heavy use of QtC (several flashes, installs/uninstalls, builds, application deployment) the device rejectesdto access the phablet with automatic authetication:
Received disconnect from 127.0.0.1: 2: Too many authentication failures for phablet

after the device was re-flashed and all the qtc packages purged and reinstated om the host the device started to ask password after the developer mode was enabled.

[Zoltan Balogh (bzoltan)]

generating new key with $ ssh-keygen -N '' -f ~/.ssh/mydevice_id_rsa -b 768
and adding manually the key to the authorized_keys2 on the device enabled passwordless authentication.

The difference is the "-t rsa" in the parameter of ssh-keygen

[Zoltan Balogh (bzoltan)]

Changing the ubuntudevice name of the key in the script fixes the problem.

[Zoltan Balogh (bzoltan)]

The ultimate solution would be to pass the public key explicitly with -i
