I just found this: http://www.linuxquestions.org/linux/...le_Permissions

and am investigating. But, in the mean time any input is appreciated.

I decided to upgrade to 9.2.1.5 the other day and went with a fresh install on my 3.0 thumb drive. I then auto imported my only volume. I added the unix share as nobody for both mapalls. Auth network 192.168.1.0/24 and auth ip 192.168.1.18 the linux box. When I mounted the share in Linux Mint 13 everything was there but I had no access to the files as they were added from various machines and had various owners. My bright idea was to chmod the /mnt/media folder to 766 ( chmod -R 766 /mnt/media ) in an effort to grant read and write permissions to any machine. Bad idea. Now when I mount the share the top level folders are there but the contents are blank. ssh into the nas and navigate to /mnt/media then ls -l returns the following:

Shell as root /mnt/media/ ls -a and -l returns:

Mounted in Linux: these are the top level folders

I know the data is there but I need to fix the permissions.
User Travis no longer exists. I believe user 1002 was user Travis. User travis is the user name of the linux box. I think what I need to do is chown the non system directories to a current user or a system user but, that's as far as I get.
I have RTFM and printed it for reference but there is not a bad idea chapter. I am wary of proceeding without input from the community. I know there are other post covering the same issue but they didn't have much for me.
I've read through this several times as well.

Any input is appreciated....

When you remove the execute bit (the x in rwx) on a directory you can no longer see the contents. You need to either be the owner of /mnt/media or change the permission to 777.

Thanks for your reply but,I'm afraid of 777. Can I create the owner? Also just to be clear, let's use the music folder, it shows:
drwxrw-rw-
so the missing execute bit would be on the end?
Another question I have is did I change the owner of any system directories? most of the owners are travis with a couple of root and uid(?)owners. Do I need to change the GREEN directories back?

Thanks again....

Might have figured it out... so if I chmod the music folder to 775, that would let the owner rwx, the group rwx and the other r-x. The executable bit makes it visible to all...
