Tino,

Having gotten accustomed to Fedora, I prefer working as root when required
instead of having to enter lines twice -- once without sudo, error, then
retype it with sudo.  Also, root can navigate to some directories that
normal user can't go.  Once I get more used to using sudo, I may put root
back as it was.  This was the ONLY reason for setting a root password.

The backuppc password is only used initially to start BackupPC CGI for
setup, I think.  I haven't gotten that far as yet.  BackupPC is installed,
config.pl has been edited, but backuppc is currently halted until I get the
keys set.  I have my LVM drive to house the backup files mounted and ready.

The Archiver machine will also be my daytime workstation in the workshop.
Therefore, I want to be able to do more than just run BackupPC at night.
Some software not pertaining to BackupPC will be needed.

Tino, in the original transcript, I didn't show work done on Winserver.

Maybe I see the problem.  On the winserver end, I put the public key in
authorized_keys2.  Maybe Ubuntu version uses a different name from Fedora.
Maybe I should have put the key in authorized_keys.

I tried using authorized_keys and got the same result.  The transcript
follows.  (showing work on both ends) -- ken
