Archive parameter doesn't preserve owner:group property!

[Tony Abernethy]

On  BOTH  sides do a ls -n whatever
This will show the numeric IDs on both sides.
Most likely the SAME numeric id will be one thing on one host and something
else on the other host.
 
Most likely --numeric-ids is doing exactly what it is supposed to do
ls -l will show names if it can find a name that corresponds to the
(numeric) id.
 
Most every tool will store the file with the owner and group of what runs on
the target.
The alternative is probably to tar the files on the source, transfer the
tarball, untar the files on the target.

I don't know if my request is clear...sorry for my bad english...

I just need to preserve ID...I don't want rsync to convert id to name group
because it takes the name group of the server instead of my local machine.


I run rsync command in local machine in root, the deamon is run in root too,
in rsyncd.conf in my module I set gid=root, uid=root...I have tried
--numeric-ids parameter...and nothing...
So if you know another tool which do that...

The uid and gid are numbers.  These numbers  **MIGHT** correspond to one or
more names.
As a convenience and courtesy, rsync attempts to preserve names across the
transfer
Who ever is running the rsync daemon must have the rights to make the
changes or there is nothing possible for rsync to do.
To preserve the groups, I think the owner can change groups to/from groups
that the owner is in.
You will want to test on you system exactly what is tolerated --- I'd expect
that the owner needs to belong to both groups.
 
If it were me, I'd use chroot and uid=root and gid=root
--- but then I've found that OPEN-NESS seems to be the only effective and
cost-effective security mechanism. (Even to ridiculous extents;)
(Everything else seems like turning out the street lights so the bad guys
can't see you)

someone??

Does I have to set gid and uid to "root"? or can I preserve initial
owner:group setting uid to "david" and gid to "rsync-users"?
Can I give to rsync-users the right to preserve owner:group? How? 
Is there a conflict between  --numeric-ids and others parameters? because
rsync doesn't preserve even "in root" owner:group if gid is a number instead
of string.

I have post to many Linux forums...rsync mailing-list is my last chance.
