Yes, it works perfect. No particular output, no needed interactions.

thanks for this useful-debug-tool-command line!
May I suggest that this command will be added somewhere in the  
Backuppc wiki, in a "check what's wrong" section....

I've tried this command and I get an error about write permission  
[see below], so I change the user from backuppc to root, do the ssh  
key exchange for root, and finally it WORKS! I've changed the user in  
the etc/BackupPC/hosts file, replacing backuppc by root, started a  
backup throught the web interface, and a backup has started. Cool!

So here comes another question :
I get a write permission error coming from the BackupServer because  
the user backuppc on the BackupServer as no write permission on a  
backuped folder. i.e :

root < at > MainServer%&nbsp; ls -la /home/
d---r-xr-x&nbsp; 5 bruno&nbsp; &nbsp;bruno&nbsp; &nbsp; &nbsp; &nbsp; 4096 
2007-10-09 14&#58;07 wikiinterne

So when this folder was copied on the BackupServer, the backuppc user  
had no write permission to create the subfolder contained in the  
wikiinterne folder, that's why the backup failed. Of course now that  
it is root the user on the BackupServer, he has all rights to create  
everything.

I believe I will keep running backuppc using the root user on both  
side, but is there a workaround? Because I don't want backuppc to  
have write access on all files on my MainServer...


Anyway thank you so much for your help!
I will keep experiencing after my vacation and I will fill the wiki  
with an "howto install backuppc on a DNS-323 with rsync".

Best regards,
Bruno.
