I copied it to the authorized keys file, and I can successfully ssh to my 
client as the backuppc user.

However, when I went to run my first full backup of my client, I am getting the 
following error...


2018-03-12 15:43:48 Created directory

I can now ssh to my client successfully though?

It should go in the authorized_keys file, not the known_hosts file.

Sorry my mistake, I have now corrected myself, and I have copied the RSA key

The public key you need to copy is the one for the backuppc user, not the root 
user, because it's the backuppc user that's going to be making the connection 
(yes, you will add it to the root user's authorized_keys on the client, because 
bacuppc will sign into the client as root).

Your initial error report shows this:
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: 
"/var/lib/backuppc/.ssh/id_rsa.pub"

This shows that it's trying to copy the key from the correct place. On my BPC4 
install, /var/lib/backuppc is symlinked to /srv/backuppc, which is why I asked 
if you were working in that folder, i.e. did you 'cd /srv/backuppc' (or 'cd 
/var/lib/backuppc')?

I'm sorry, I'm not too sure on what you mean by working in /srv/backuppc?


I copied and pasted the RSA key from my backuppc server to my host I would like 
backing up. I ran the following commands,


On my backuppc server:

cat /root/.ssh/id_rsa.pub > id_rsa.pub_copy


On my host server:

cat id_rsa.pub_copy >> /root/.ssh/authorized_keys


I then switched users to backuppc, and tried to ssh to my host, however, I was 
still getting Permission denied (publickey,password).

Are you working in /srv/backuppc?

What is the error message?

If necessary, copy the public key to a regular text file, send that to the 
host, then log into the host and append it to the authorized_keys file.

Hi Robert,


I tried what you had mentioned, but sadly that didn't work. I'm still getting 
permission denied when I try to copy the RSA key to my host.

You can work around this using something like this:

rsync .ssh/id_rsa.pub root@10.16.0.16:/root
ssh root@10.16.0.16<mailto:root@10.16.0.16>
cat id_rsa.pub >> .ssh/authorized_keys
rm id_rsa.pub
exit

So I've tried to copy my RSA key to one of my hosts whilst I was root, and that 
worked fine, I could successfully ssh into that host. However, when I switch 
users to backuppc, and try to copy the RS key to that same host, I still get 
the same error as stated in my previous email.

I don't know why I cant copy my RSA key to my host whilst I am the backuppc 
user?

I tried using su - backuppc -s /bin/sh instead and that worked, it allowed me 
to switch users to backuppc, however, when I try to copy the RSA key to my 
hosts I'm getting...

I've installed BackupPC 4 and I cant switch users to backuppc to add hosts?


I've tried...


su - backuppc


but it just keeps going back to the terminal, it never switches users.


I've tried adding hosts via the GUI, and for some reason, the backups are 
failing giving the same error message...

2018-03-05 09:00:01 Can't find host 
ukat2<http://10.16.0.163/BackupPC_Admin?host=ukat2> via NS and netbios
2018-03-05 09:00:01 can't ping  (client = 
ukat2<http://10.16.0.163/BackupPC_Admin?host=ukat2>); exiting

Not sure what I'm doing wrong?
