Change Permissions

Hi @All,

I look stupid and dumb and the longer I look, the less I understand ...

Under Linux, I created a library on a NAS with Calibre. I want to synchronize these files in Windows with a local HD but I have the wrong permission.

The MAN pages for the command chmod and chown does not help me because I did not find out what permissions exist to those files. The "ls-l" command shows me only "drwxrwxrwx" and the user name.

What I need is an assignment to a group without a user name because I want all users of this group can work with this library.

Is there no front-end for managing permissions?

There are various front-ends for permission management, including right-clicking on a file or directory and selecting "Properties".

But it would be better to understand how Unix file permissions work, because what you are attempting to do is one thing, while what you THINK you are trying to do is another.

You do not want to assign "no user" to your files, you want to assign a single group to them, and then you want to ensure that that group has permission to read and write those files.

If `ls -l` shows drwxrwxrwx (777) permissions, then your current user and its current group, and all others, have full permission to the files. So that's very permissive and in theory you should have no problem there. But since you are, I am guessing that either the directory they are housed in has more restrictive permissions, or else you have some configuration issue in the way you are accessing the NAS over your network.

What are the permissions of the directory? and how are you accessing the NAS?

Hi notKlaatu,

after all my attempts to adjust the permissions were unsuccessful, I've found another way.

I've moved the Calibre library with Mint (Krusader) from the NAS to an NTFS partition and then copied with Windows FreeFileSync back to the NAS. Now does the sync work in all directions. :-)

I think this thread may be closed.

It is still a very good idea to do a little research into permissions and the structure of the file hierarchy. That knowledge will be useful in the future.

I assume you're using CIFS/Samba? (AKA Windows file sharing)

If so, you'll need to be sure your Samba permissions are configured correctly, in addition to the appropriate permissions on the Linux filesystem.
