Unix permissions from Windows

Question

Hi all, I have a D-Link DNS-323 NAS, running some sort of Linux as its OS. I map a volume as a share in Windows Vista (Ultimate SP2). There are some directories and files on that share that I cannot change/delete - no matter what I try. Trying all of Windows security/permissions dialogs don't work, as the files owner is "Unix/root" and all other Windows users have read-only permissions.

I managed to ssh into the OS and verified that these files belong to 'root' - the user under which I log in, and all the other files (the ones I can change) belong to 'nobody'.

All fine and well, while I'm in ssh, I can always "chmod +w" the files, or "chown nobody". But my question is this: how can I make my Windows user (let's call him 'admin') impersonate 'root' on the Linux, so I can simply manipulate files from Windows, without resorting to ssh?

In other words, and to make the whole question plainer: how do you tell your OS that a certain user on Windows is a certain user on linux? (that way, I can have 'admin' be 'root').

Thanks in advance, Guy

Answer 1

Cygwin can do that.

EDIT:

The cacls command in Windows looks like it does what you want.

Answer 2

Samba can do something like you've said. it basically emulates windows compatible permissions on a linux box..

Answer 3

Assuming the NAS is running samba (almost certainly), there should be a samba config file somewhere in /etc. But I don't know if it would be editable.

The remapping between windows/Linux and permissions is all done on the server (samba) side.
There are a lot of Samba faqs about this.
