During the installation of the openSSH-server the setup (apparently) asks for a username and password. However, a split-second before this screen appears I pushed the 'task-overview button'. I saw the screen, but the finger movement was already unstoppable ;-)

The problem: when I returned to the app-manager this screen was disappeared and I couldn't 'find it anywhere'. The installation seemed to be finished fine. I uninstalled immediately all the openSSH programs and tried to install it again. However: it didn't ask for the username and password again.

My question: do I know have a user 'blank' with password 'blank' or something? What should I do to setup all the openSSH configs and users correctly?

Many thanks!

As root dpkg --purge openssh-server
Then try to reinstall it (you can also change the root password which is the same as the openssh-server one)

Or you can just open X-term and change the password there.

Purging the installed package won't undo any changes done to /etc/passwd and /etc/shadow.

Installing the package again might very well not ask for a password since these files have changed already.

You change passwords using the passwd command. Berome root and type the command alone to change root password. As root,changes the password for the named user.

Thanks to the answers! I thought to have seen a 'Username' and 'Password' field, but it turned out to be only two password fields for changing the root password. So after installing again I changed the password using 'sudo gainroot' and 'passwd'. Everything seems to be working ok now!

Still, this might be worth filing as a bug against openssh, as I don't think that dialogue should disappear just because you task-switched.
