[Hidden-tech] DLink DNS-343 NAS device / Linux - how to set / change permissions...

[Donald M Stevens]

Good Afternoon All..

All great info….. not fixed yet, but I am learning….

Okay,
DLink DNS-343
Uses I believe a Unix / Linux O.S.
Basically this is a NAS device with mirrored drives
We create Volumes, Shares, Permissions and user accounts and groups through a Web Interface

1.       From here I create “Volume_1” and give “ALL USERS” read / write access

Then we go over to the Windows Computers (yes, mostly windows, some MACs all with the same issue)

2.       We map a drive say “Z:” to “//Dlink-NAS/Volume_1”

3.       User connects, can view and work on 90% of the files and folders

4.       However, there are some files they can see, but cannot open, copy to another drive, etc….

Does this help?



Thanks!

How are you accessing the files and attempting to set permissions. The comment about chmod implies either you have a Unix/Linux access (or, maybe FTP), but you mention you're using Windows, too. Windows doesn't do chmod. (Well, now with Bash implemented in Windows 10 Anniversary version, maybe it does.)

There could be two kinds of permissions affecting what's going on. The device, itself, has its own security system. But, depending on how the fies were created, there may be some things going on related to Windows permissions, access control lists, and whatever else may have been cooked up by D-Link and Microsoft in the handshaking that goes on when files are written.

Hi Donald~

Have you tried the command line “chmod”  command?
Here’s a link to a pretty nice page that explains it:

Good luck!

Good Afternoon All,

I have a client that uses and DLink DNS-343 NAS Device. Basically it has (4) 1TB drives in it.
These drives are mirrored.

Within the Admin tool, you can share / create volumes / set permissions

Okay, so the permissions are set to allow everyone READ / WRITE

I have admin permissions

However, when we browse to some folders, and some files in those folders, we cannot open them.
We get access denied.

Using Windows, I can view the permissions, but not set any permissions.
It shows that the group everyone, has NO PERMISSIONS on the files that we cannot access.
(makes sense)

So, I have reset this DLink NAS device, updated the firmware…… twice
I have deleted and recreated the permissions and shares….
Rebooted…..

Still having the issue with random files I cannot access.
I did even try to just copy  them elsewhere, but it will not allow me to do that.

I do not know much about Linux or Unix (could be using this O.S.)
Is there a way to force the permissions to change, say from a command line?
There is no command line tool for DLink DNS-343 (least that anyone knows about.

I have been working on this for two weeks now, my client cannot get to their files.
I have call DLink tech support, many times.
Currently, I have a contact person who is supposed to be “LEVEL THREE” (think you get this person if you wait “3” weeks?)
This “Level Three” tech now has my case sent over to China where this device was made. So far no return call from them, however they mentioned they want to do a screen share…. I told them bring it on! Anytime! I will stay up all night!

So I thought I would just send this out to all you hidden techers….. maybe someone has something I have not tried?

Oh, one suggestion I got from the tech that installed this a few years ago, take one of the drives, attach it to the Windows Server or Windows Desktop and read the files from there…..
Tried that, no luck, Windows could not read the drive in either case.

If I do figure it out, I will post the answer…. Might be a while….

Thanks!
