Hi Luis,
Even before I got your note, I think figured out the problem. With so
many changes since I started rebuilding the archiving server, problem
generating keys, getting keys generated and then deciding to not use
root logon, I simply forgot that I had not generated keys for backuppc
as a simple user!
I logged in as backuppc on the archiving server and created an rsa key.
This was then ssh-copy-id <client1>. This seemed to work properly with
a note to 'ssh <client1>' to test the key. I issued command 'ssh
<client1> and connected without a password request. <archiver>
represents the server running the backuppc software, <client1>
represents the real client machine_name and <share1> represent the real
share_name.
----------------- backuppc ssh logon -------------------------------
backuppc@<archiver>:~$ ssh <client1>
Linux <client1> 2.6.24-27-generic #1 SMP Fri Mar 12 01:10:31 UTC 2010

---------------- end of logon session ------------------------------
I thought that it should work now, so I requested a manual backup. The
command seemed to be accepted and the log showed a full backup had
started. There was a bit of activity for about a minute, then nothing.
After a few minutes with no activity, I stopped/dequeued the request. I
am closer, but haven't gotten it all in place as yet. I didn't get any
error until I stopped it. It said:
2010-03-22 21:20:24 full backup started for directory /media/<share1>
2010-03-22 21:38:19 Aborting backup up after signal INT
2010-03-22 21:38:20 Got fatal error during xfer (fileListReceive
failed)
I am wondering about the text generated in response to the logon above.
When I logon with a password, I get the password prompt, enter password
and get the last login message. This is the first time I've seen the
text "Linux <client1> 2.6.24-27-generic / ... cut ... /
http://help.ubutu.com/"; Could this be messing up the process?
I also have another question. I seem to remember something being said
about the restore process and having to give a password for root to do
the restore. I know that I have to switch the lines in sudoers as well.
Do I need to create a key for root with a strong passphrase on the
client machines and append it to authorized_keys in /var/lib/backuppc?
As soon as I get the backup working, I want to test the restore
function. If that doesn't work, there's no sense having a backup!

That usually means something printed text to the connection
before or instead of
starting rsync. Are you sure it isn't asking for a password or
displaying the
condescending sudo message (or a message of the day) as the
connection starts?
