Oh I see. The image was built with wharfie. Seems like I didn't commit the Wharfile with which it was created.

I will update that soon. For the meantime:
I think the password was the default, which I usually use in the wharfie examples. Thats root:wharfie and wharfie:wharfie.

wharfie:wharfie confirmed.
I believe root password is not «wharfie».

No, you're right. It's root:root in the examples ;)

I believe root password is not «root».
Sorry for caused trouble (again).

Hi, is it possible to have the root password?
Thanks in advance for your kind assistance.

Hi Daniele!
It definitely was root:root. But actually your are not allowed to login through ssh as root. It is very common, that this is not allowed on linux. As a workaround, you can login as a user, and use su to gain root access:

$> ssh wharfie@192.168.100.100
login as: wharfie
password: <-- here you enter the wharfie password

$> su -
Password: <-- here you enter the root password

Here I committed the Wharfile with which the image was built:

YES!
It is the way you say.
Thanks once more for your kind help.
