Hi,

On my Debian server I installed Samba for sharing directories in my local network. I know how to set access rights but I have a problem. I would like to allow an user (example "nobody") to create files or directories in a shared directory but to deny to modify or delete something.

How can I do that?


Second question, on a file, I know that we can set rights for "u", "g" and "o". But like the NTFS permissions, can we apply rights for each users?


Thank's a lot for your response.

NTFS does not support permissions.

And if "nobody" creates a file, do you want "nobody" to be able to delete the file he created?

1 - Basic ) change All files/dir in SHARED(o+rw/different user) folder to o+r-wx/different user. nobody can create files/dirs and delete them but can not delete all other files/dirs in this directory.
1 - Dynamic)I see a good way to upload to folder with o+rwx and after some time (based on cron job) change user/permissions on dir/files in it to u+rwx,g+rwx,o+r-xw/different user(or move to dir that have read-only access from net)
this way uploaded files (lets say in 12h time) can be changed but after 12h will only be accessed for read. This way you can mix old read-only files and newly uploaded.
x)i also saw somewhere(smb.conf?) option to create files with default mask (umask analogue)
x) there is umask command that change new files default permissions(it may work if you spawn samba as separate shell script). umask o+r-wx, echo >newfile, newfile (o+r-wx)

Ok, thank's. With umask I can do what I want.

But on windows, on NTFS formated hard disk, you can set access right for each user. My question is: Can we do the same thing on Linux? Because normally "u" is for the owner, the "g" for the groupe and "o" for others.

All I ask is bound. Because I make a Samba share on a folder containing many files. The shared folder contain a website with video file and the owner of each file is "www-data" and his group "www-data". But I want to share this folder with Samba. I would like to add a user in the rights of video files for him to see. The file. Html,. Php. Css, ... must be invisible to the user.

How can I do that?

Thank's !!!
