UNIX for Dummies Questions & Answers

Thank you for your reply. I don't have Cygwin installed on the Windows server. I only have Services for NFS. As for the rsync command, I don't want to preserve the permission at the source as it will overwrite the Windows destination permission.

Windows server 2008 Standard
Linux1
Linux2
It is quite cumbersome to make the ownership changes and manually do the permission changes each day in order for clients to make changes to the Windows files.

I need to find a solution for rsync to make changes to the data while keeping the ownership (Administrators group) and permissions intact.

I'm not too sure how the mapping works but the domain is specified. I'm guessing the user used by Linux to mount and rsync points to a specific domain user. How it chooses the user in the domain I'm not sure. I've noticed that the Linux user (test) points to domain account which contains test (test DOMAIN\1_2_test). Perhaps Linux user maps to same name user in the domain(or has that same name in the userID). But that domain user seem to overwrite the ownership of the file and adds Full Control in the permission which I want to avoid.

I'm not supporting the 2 Linux boxes but I can find out if you need more information at that level.

Hope I've cleared it up a bit more.

It appears that all that you need is the -r flag, which will copy data recursively if needed by do not preserve the original timestamp or permissions.

Code:

rsync -r

We tried just -r but the problem remains. The ownership changed again to domain user and the permissions was wiped again.

Can you loose the -p option, and try with following (taken from the rsync manual)

Code:

To give new files the destination-default permissions 
(while leaving existing files unchanged), 
make sure that the
--perms option is off 
and
use
--chmod=ugo=rwX (which ensures that all non-masked bits get enabled). # you can try without this...

Other then that -p option will do the following :

Code:

This option causes the receiving rsync to set the destination permissions to be the same as the source permissions

Which you obviously don't want.

Thanks for your reply but we've tried that already but with no luck. It might be related to UID and GID mapping between the Linux user running the NFS mount, the rsync and Windows server. It might not be working properly.

I have enabled the KeepInheritance under the ServerforNFS on the Windows server in the registry and waiting for test rsync.

The rsync command from what Peasant has suggested will be used. I will confirm once I get it tested.

I was thinking of scheduling the change of ownerships and permissions through a batch job on all affected files and folders daily but we have too many files and folders to perform this.

I just got word from our Linux support that --no-perm does not execute as the rsync version is too old. The version is 2.6.2. We will try upgrading our rsync version and we'll try again when the new rsync version will be implemented.
