Hi Luis,

I really appreciate your help.  I've tried the key generation multiple
times and can't believe that every time I mistype the password!  The
keys are phrase-less.  /root/.ssh and /var/lib/backuppc/.ssh have 700
permissions.  The authorized_keys file has 600 permission.  The newly
created keys have 644 permissions and are set after transfer with the
command:  chmod -R go-rwx ~/.ssh

On the server, I su to root then su to backuppc.  Working as backuppc,
the command that is not working is:

scp ~/.ssh/BackupPC_id_rsa.pub r...@192.168.1.101:/root/.ssh/

I get no error, just a prompt to enter the root password for
192.168.1.101.  I enter the password, but it is not accepted and asks me
to try again.  I can occasionally mistype a complicated password, but I
have carefully checked each key stroke.

Working as root on machine at 192.168.1.101, the command that is not
working is:

scp ~/.ssh/client_id_rsa.pub
r...@192.168.1.106:/var/lib/bacuppc/.ssh/client_id_rsa.pub

Again, no error and prompted for root password which is not accepted.

I have root passwords for both of these machines and have no problem
elevating to root to execute all other functions.


As a test, I ssh connected to the backuppc server at 192.168.1.106 from
192.168.1.101.  I issued the following command:

scp /home/ken/20100308.backuppc_install.txt k...@192.168.1.101:/home/ken/

I was prompted for password for ken and the command completed with no
problem.  -- ken
