ah, but that is *not exactly* what BackupPC does. Can you
backuppc@backuppc-server% rsync [email protected]:truc.txt tmp/
without any problem, manual interaction or extraneous output?

Well, removing the "banner" directive should have been enough, I guess ...

Good. That was necessary in any case.

Yes. That is what you asked for. You started an rsync server, so you'll have
to be an rsync client ... start typing ;-).
rsync basics in brief:
The way rsync works is by exchanging a special protocol between the rsync
client and an rsync server. The server can be an rsyncd or an invocation of
"rsync --server" automatically started over a remote shell. The client can be
an invocation of "rsync" (without "--server") or File::RsyncP.
You aren't running rsyncd, so the server is "rsync --server" in both cases.
BackupPC uses File::RsyncP and starts the server over an ssh connection (see
your log excerpt above). "rsync root@bla:truc.txt tmp/" automatically runs
"rsync --server ..." over "ssh root@bla". If you want to test the command
BackupPC runs, try, *as the backuppc user on the BackupPC server*,
% rsync --numeric-ids --perms --owner --group -D --links --hard-links
--times --block-size=2048 --recursive --ignore-times
[email protected]:/home/temp/ /tmp/anywhere-you-like
Does that work as expected? Does it ask any questions? Does it output anything
strange? Anything at all?

See "rsync basics" above. The command you are referring to starts the server.
The rsync server command line syntax is of little interest to us. BackupPC
knows which order the parameters have to be in, so we don't.

Please verify that backuppc can 'ssh -l root' without password prompt.
The rsync command I gave you above does that, but once more: you need to run
it as the backuppc user.

See above.

That's what it is supposed to do. Neither source (".") nor destination
("/home/racine/wikiinterne") are remote, so it's a local copy you requested.
Hope that helps.
