rsync: chown "dir name" failed: Operation not permitted (1)

When you mount an NTFS filesystem on your Linux box, you're subject to the permissions as defined on the "host" system -- in this case, the Windows Server (regardless of the windows version: 95....2008 if it's providing you access to the files that are on ITs hard drive, then it is a server).

So your problem appears to be that you assume (incorrectly) that the root user on the target system gets root access to the NTFS filesystem (it does not -- and in fact, on most installations, the "root" user is a special case whose permissions are "reset" to "nobody").

As noted above, you'll need to modify your rsync command to tell ssh to use a specific UID and/or GID when running on the target system... and that set of credentials must have rw access on the /linux share (again, those permissions come from the Windows NTFS server, NOT either linux system).

It helps to simply remember that the real set of permissions comes from the "host" -- the system that has a physical connection (IDE, SATA, SCSI, etc.) to the drive on which it is stored.

I hope this helps!

Hi,

Thanks for your support.

I have mounted my windows share with UID and GID option but I confused that my remote machine share is a common share which have access on 100+ users with their own UID and GID.

Please advise in this condition how can I choose UID and GID for mounting windows share.

Presently my windows share I have mounted as a privilaged user who has rw permission on windows share.

mount //windows/sharename /linux/dir -o username=root,password=test

In that case it gets slightly more complicated....

What you will need to do then is the create a map between the IDs  (PID & GID) on the Linux side for each user on the Windows side. Look at the IDMAP_RID with Winbind section of http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/idmapper.html

At that point, you may want to ask yourself the question, is it the right solution to mount the drive with Samba? It may be easier to get rsync services up and running on Windows, as described in: http://justinsomnia.org/2007/02/how-to-regularly-backup-windows-xp-to-ubuntu-using-rsync/
That will require cygwin on the Windows side, but may not be a problem for you as much.

Thank you very much for your great support.

In that windows machine I cant install the rsync software because its in production...... so ...

I will add my samba machine to ADS and will update you the status.

One more doubt so in this condition I have to give everyone read and write permission to samba(windows share) ? if it is then there is a problem in security ........

please advise

No, once you establish the samba server on the AD domain, permissions will (correctly) be established by the Windows system.... so you'll need to access the files with a valid system account (it is perfectly acceptable to force the root user to be a member of the Domain Admins group, or to use another user ID that is a member of the Domain Admins group).

So it is NOT required that you give read/write permissions to all...

I hope this helps!
