[BackupPC-users] Exchanging keys

Dear Richard:

Again, you're a godsend. I can root ssh to the Thecus!

But I wish exchanging keys were that simple with the Thecus NAS. The Thecus has a sandboxed operating system. Anything below /raid will be eaten up on reboot. To do keys you have to use a module called FajoSSHD that's located here on the Thecus:

Office-MacBook-Pro:~ bobkatz$ ssh [email protected]

N6850:~# cd /raid/data/module/FaJoSSHD
# ls
cgi-bin/ log.txt Shell/ system/ www/
COPY shell@ sys/ VERSION
N6850:/raid/data/module/FaJoSSHD#

I know that FajoSSHD keeps authorized keys in here:

N6850:/raid/data/module/FaJoSSHD/system/etc/ssh/users/root# ls
authorized_keys

But I cannot figure out where the public key you want me to transfer should go. Would it go into that same directory? If not, I can explore any other directories. Somewhere in this hierarchy I need to put the key which I generated on my Fedora server.

I'm going to try your code and see if I can get it to work using the above url. Stand by.

Thanks,

Bob

The easy way to exchange keys on Fedora to use rsync over ssh assuming
you're using root to do the backup on the clien:

(as root)
# su -s /bin/bash -l backuppc
# ssh-keygen
(don't add a passphrase, it would defeat the purpose)
# ssh-copy-id root@<client>

After that you should be able to "ssh root@<client>" and it login without
prompting for a password.

Thanks,
Richard
