Linux based NAS with a Windows domain controller: Permissions


Recommended Posts

Hello

I seem to have trouble with a Linux based NAS that I have made part of a Windows (SBS 2003) Active Directory domain. When I made it part of the domain, all the domain users have passed to it.

I cant write to the "root" of the NAS so I make a folder. Inside this folder, I copy all of my old data to it. The problem is that the permissions dont seem to pass or pass only sometimes....

To copy I use this: http://ipmsg.org/tools/fastcopy.html.en because it supports ACL.

The domain clients are Windows 7 and Windows XP. The NAS is a QNAP TS469U-RP.

Thank you for all the help

And what are the permissions? Just set them! And don't copy ACLs -- when you copy files they should use the permissions of the folder / drive you copy them too.

Set the permissions you want on the drive/folders of your nas! Sounds like you want to be able to copy to root? if so then correct the permissions..

What are you having trouble with about understanding permissions?

The problem is that it is suppose to be automatic: When I copy from the server to the NAS, the permissions go with it. The permissions I am talking about are:

FolderA : User1 can write, User2 is owner, All of group Users can write, etc.....

That is what is not being passed.

And I do not want to do it manually because there are a lot files/folders and one of the features is that it supports passing ACLs....

Lets see the permissions please!

Screen shots works, lets see the effective permissions tab as well with a couple different user names put in.

example - this is from a client just right clicking on the share

If you NAS is linux based, make and model like sc302 suggested would be helpful.

ls -la listing from linux console for your files and directories would be helpful in seeing permissions set via linux.

for linux to use windows permissions you have to map them to a linux user normally.

Also you can copy ACLs with /0 in the builtin xcopy command

 /O           Copies file ownership and ACL information.
Or robocopy as well, another built in tool can copy permissions

/COPY:copyflag[s] :: what to COPY for files (default is /COPY:DAT).
                     (copyflags : D=Data, A=Attributes, T=Timestamps).
                     (S=Security=NTFS ACLs, O=Owner info, U=aUditing info).

      

             /SEC :: copy files with SECurity (equivalent to /COPY:DATS).
Keep in mind where you making a copy from - if any local permissions have been set its unlikely those would work, match up to domain accounts via SID, etc.

As setting permissions on your NAS, I would assume your wanting to remove the old files after you copy them.. So its just easier and cleaner to create the permissions you want to use on the device doing the shares vs trying to copy them.. Only reason to take the permissions along would be if you had complex permissions on each file, etc.

You can run into problems if inherit flags are being used on source or dest and they conflict or don't line up, accounts to map correctly, etc.

what I would suggest is to use iscs vs nfs.  it will be much better for you if your ad permissions aren't being applied.  It would be best if you could dedicate a nic for it, but it is not needed.

I actually was intrested in iSCSI the problem with it is that Im not completely sure how it works and we were already using a "shared folder" type structure so the transition would be "transperent", we just decided to go with this.

If you could share some document with iSCSI and AD permissions, Ill consider trying it out :)

Another kicker: On the server there are groups I can add permissions for and on the NAS I cant!

On the left side, you see users/groups I can add for setting their different permission settings. This is the AD server.

But on the right hand side, you see the users/groups I can add for the NAS server. Shouldnt it, since I am accessing from the AD server, be the same?

Scratch all that: Just read it is by design. God, this is going to make my life a bitch :(

Not sure how in-depth you want to get into Linux but I managed to set this up using Software RAID6 on Linux with mdadm, 4TB  and got results of about 300MB/s read and 300MB/s write (That's MegaBytes not bits).  Wired that up through my place over a 1Gig/s network for around 120MB/s R/W to from that.  About 6 steps. 1 step to do the RAID.  So around $800 for 4TB and those speeds.

 

Here's the page about all that and it actually works as posted:  

 

All shared with CIFS and secured by selinux (Having said selinux, maybe that's where the issue is with yours?  Not sure.  Ran into the same thing with my custom one):

HTPC / NAS Backup

 

Sharing with Samba / CIFS

 

But like I said, not sure how in depth you want to get into Linux though having an entire OS behind the setup will give you lot's of tools in case of issues and not a closed down box.

 

HF!

    • Jony Ive is reportedly working on multiple AI devices for OpenAI, including a mobile gadget by Hamid Ganji Last month, OpenAI announced acquiring Jony Ive's startup, io, in a $6.5 billion deal. Ive, who served as Apple's design chief for over two decades, moved to OpenAI to work on the company's AI hardware projects. While the details of these projects have remained relatively untold, Mark Gurman's Power On newsletter revealed some exciting insights about Jony Ive's work at OpenAI. According to Gurman, Apple's former design chief is now spearheading a series of groundbreaking AI hardware products for OpenAI. One of these under-development devices is described as a "mobile gadget" that takes the form of a "pendant" and can be worn around the neck. This device could allegedly allow users to access ChatGPT with voice commands. Another of Ive's works at OpenAI is a home device that functions similarly to a smart speaker. Users can put the device on a table and perform various tasks using OpenAI's ChatGPT. Interestingly, OpenAI also has a robot device under development. As Gurman says, this robot "will likely be a machine that develops a relationship with a human using AI." However, OpenAI's robot is still far from being made available on the market. After acquiring Jony Ive's startup, OpenAI CEO Sam Altman described Ive as the best designer in the world, adding that they can now work on the next generation of AI-powered computers. More details about OpenAI-Ive hardware products could emerge over the next few months. OpenAI was already rumored to be working on a mysterious AI gadget, presumably a screenless AI phone, which might be the same mobile gadget that Gurman revealed. While details of this alleged AI mobile are yet unknown, such a device could pose an alternative to conventional smartphones, raising the alarm for smartphone makers such as Apple, Samsung, and Google. Meanwhile, Apple might already be expecting such a device, as its services chief Eddy Cue allegedly said during his testimony at Google's antitrust case that iPhones might no longer exist 10 years from now.
    • Seems Nintendo have already thought of that after the Joy-Con drift in the Switch 2 EULA: Clause 16 of the EULA reads: "This arbitration provision precludes you and Nintendo from suing in court, having a trial by jury, or participating in a class action. You and Nintendo agree that arbitration will be solely on an individual basis and not as a class arbitration, class action, or any other kind of representative proceeding. You and Nintendo are each waiving the right to trial by a jury."

    • I can't say I ever noticed an OEM putting effort into user-friendly descriptions and icons who didn't also put effort into making good drivers. Usually, missing icons and descriptions was also a sign of bad drivers.
