All these issues APPEAR to deal with the fact that despite configuring the permissions, umask and inheritance correctly in NAS4Free, there are problems with users accessing files and folders created on shares.
My situation is similar. I have a home multi-OS environment (Windows 7, Linux Mint, Linux Ubuntu, OS X Tiger [yeah, I know, it's old]). Anyone using OS X or Windows, or Linux Ubuntu can create, modify, delete, copy and move files and folders on the share drives with no problem. However, from my Linux Mint machine (my personal desktop), I can create a folder, but I then cannot then copy anything into it. If I'm doing a mass copy or move, only some of the items can get copied or moved before the operation fails due to permission failures.
The reason seems to be that, like Minorlemming, everything I create is created with 755, no group write permissions. In fact when I did a ls -l on those created folders/files it came back with the pair nogroup:wheel. So apparently, I'm not even the owner.
So everytime I have to copy/move items, I'm constantly running chmod 777 -R on the folders making the whole effort really time consuming.
Reading more about this on this site I found that it says in the documentation that if you are using the anonymous authentication (which I am using),
So first I created an account on the NAS and set it to the guest group primary and the nogroup as secondary. Same problem.Users accessing resources shared by CIFS/SMB are using the credentials of the Guest Account, see Guest Account. User Names and Passwords will not be required of any client accessing shared files that are owned or accessible by the Guest Account. Files not owned or inaccessible by the Guest Account will not be accessible.
Then I deleted the account (since authentication was set to anonymous anyway), rebooted my machine and tried again. Same problem.
I looked at @raulfg3's suggestion at the end of "umask / permissions to create group-writeable directories", but when I checked my root directories via the shell on the NAS server, all of the root directories were already 777. The folders are all owned by ftp:nogroup. Inheritance is checked. But created or copied files and folders still get 755.
So is this a bug or is there something I am missing? Does the guest account somehow not have full access to these files and folders? How can I check for that?
Thanks
