Setting ownership & permissions on DTU-connected printers

Can anyone provide a pointer to info on how to automatically set USB printer ownership and permissions across a FOG? As it stands, when the devices in the /tmp/SUNWut/units/IEEE802.001<MAC> tree are created, they have owner/permissions that prevent CUPS access. Can custom permissions be applied automatically when a session starts on any server ?
Thanks,
Jim

I have attached the screenshots.
The exact scenario is I want to give full access permissions for the AD group CONSTRUCTION for the share WHIHC.ETA for the folder 04.Construction, When I give permission it is not throwing any errors or something.

Accidently changed the "ownership & permissions" access admin setting to "read only"

In the "Get Info" window on my MacBook hard drive icon, I accidently changed the "ownership & permissions" access admin setting to "read only" & now it won't re-boot the operating system. Just displays the Apple logo & running wheel on a white screen . Any advice on how best to re-set/restore would be very much appreciated, thanks

This might help. Otherwise, it might be necessary to reinstall.

If they have set up port forwarding for you already then that is different. In that case, then you could be experiencing the bug with the most recent release of ARD (3.7.2) and in particular ARD 3.7.2 and Yosemite ARD version 3.8 clients. It has been reported numerous times in the forums and to Apple that since 3.7.2, clients are frequently unavailable to connect to despite there being no network issue between the remote computer and client computer. I have not seen anyone report it who was working from outside the LAN to inside the LAN, but I have the same issue with a number of my own computers that are simply on a different subnet, so it stands rot reason that it would happen from a port forwarding location.
I am sometimes able to resolve the issue locally by SSH connecting into the client computer using Terminal on my admin machine and restarting or relaunching the ARD agent on the remote device, then trying to connect to it again after about 30 seconds.
The Terminal commands for this procedure are as follows, though you might need to include a port number from outside the LAN:
First:
ssh ipaddress -l adminusername
(example: ssh 192.168.1.1 -l macadmin)
Second:
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -restart -agent
After that, waiting about 30 seconds and trying to observe or control usually works, though the computer may still fail to show an online or lit-up status indicator.

Task or script to monitor file ownership, permissions and change as needed

I'm using a Mac OS X Tiger (10.4.9) computer as a file server for a group of people who are (1) individually non-administrative users and (2) members of Groups. The hard drive is partitioned into 2 volumes: Vol1 has no non-admin access, Vol2 has a Shared folder containing folders with files intended for either Public or Private access. I'm admin with UID=501 and trying not to be a danger. Each other user has a unique UID. Each Group has a unique GID. The folder that all users have access to is named Pub_shares. Every user allowed to access Pub_shares is a member of PubGroup (GID=505).
Now when a user accesses a file nested in Pub_shares, that file usually becomes owned by that user and the group membership may change from PubGroup and may undergo a change to "Read only" or "No Access." Since all members of PubGroup should have Read & Write access to files in Pub_shares, this is a problem. All files in Pub_shares, regardless of who last touched them, should remain:
Owner = chris / Access Read & Write
Group = PubGroup / Access Read & Write
Others = No Access
I've read some about Ownership & Permissions. I've seen it suggested that an admin set up an automated task, say to run every 3 minutes; that task checks file ownership and permissions and, if different, changes the values recursively to those shown above, such that:
Owner = 501 / Access = rwx
Group = 505 / Access = rwx
What do I need here? An Automator workflow? A shell script? AppleScript? Cron? launchd? How do I put this together? I don't know the syntax or the expressions to use. Any help is much much appreciated. [Note again: My "server" runs Tiger 10.4.9.] Thanks.

..."I have some Windows users (trying) to access shared files. Will the afp inheritance options stand up to a Windows user?"...
No the afp inherit settings won't apply to windows sharing, but I think there are equivalent settings that can be applied to smb.
..."I thought, too, I'd read somewhere that inheritance options use the topmost volume folder to set inheritance patterns."...
I am not able to double-check this for Tiger, but I don't think that is the case. As far as I know, with those settings enabled (and it doesn't work reliably if only one is enabled) permissions and ownership should be inherited from the folder that the items are added to.
..."My topmost folder on vol2 is "Shared" but it contains both Pub_shares (accessible by members of PubGroup) and a few Private_shares (folders accessible by members of various private groups)."...
Sorry I missed that point in your earlier post. The above would cause complications if a user were to move items from the private area to the public area. The inheritance only applies to when files are created, so something moved from the private area to the public area would retain its original permissions. To make it work, the public and private areas would have to be set up as separate shares, rather sharing the whole volume.

The correct Ownership & Permissions on external firewire disks?

I was excited by a resolution to the same problem I have (I don't know what Ownership & Permissions I should have on my external -- bootable -- HD). Mistakenly I used Leopard to set them up rather than Mac OSX 10.4.11. Now I no longer had access to the HD nor would it show up on the desktop on Mac OSX 10.4.11 although the Disk Utitlity showed that it existed. I finally erased and cloned the disk but don't know what Permissions I should set it at. "Niel" supposedly answered this problem but his answer was "click here and follow the instructions" which does not show up on the forum. I can't find any other discussion of my specific problem nor an explanation of various permissions sets for Hard Disks internal nor external. If someone could help me I would be grateful. I am in Japan far from any Apple Stores or shops. Thank you.

For a bootable drive or system drive:
owner=system w/read-write privileges
group=admin w/read-write privileges
other=read-only privileges
The box labeled "Ignore permissions on this volume" should be unchecked.
To set the ownership and permissions select the drive and press COMMAND-I to open the Get Info window. Click on the small triangle where you see the label: Ownership and Permissions.

Can't see external HD partition on finder, changed Ownership & Permissions

Hi all, a friend has a particular issue with his external HD. He clicked one of the partitions on his external HD and started restricting the options under Ownership & Permissions, until he got ALL permissions set to "no access". Now the HD appears, but the partition he modified does not appear on his desktop or finder, also when he runs Disk Utility he sees both partitions, but the one he changed the permissions/access of, appears as a blank document icon, like when the OS doesn't know with what to open it with, therefore, he can't select it again and click get info/change access again. Any help, tips please? Thanks in advance mates.

[SOLVED] systemd: ownership/permissions enforcement on /run

I'm running sabnzbd on my laptop, under systemd. I'm also running it as my own user, rather than the sabnzbd user. In order to do this, I need to be able to write a pidfile within /run/sabnzbd/. The permissions on this directory are 0755, and it is owned by sabnzbd:sabnzbd. So, I need the permissions to be 0775, so that my user (in the sabnzbd group) can write to this directory. I chmod'ed it manually, but something seems to be enforcing permissions (and even ownership, as I have also chowned it to my user only to see it return to 0755 and sabnzbd:sabnzbd).
Right now, as a workaround, I have a cronjob running every 5 mins that checks /run/sabnzbd and sets its permissions to 0775 if they are not set that way already. However, I'd like to find a more permanent solution. I've yet to find anything by searching the web, so I don't know if this is sabnzbd enforcing ownership/permissions or if it is something else. If anyone has more insight into this, it would be very much appreciated.

Removing ownership & permissions for all files burned to a DVD?

Hello,
I am new to the concept of "ownership & permissions". Do they apply to files burned to DVD or just the files on the computer? I would like to burn some files onto a DVD for backup and I do not want to copy the "ownership & permissions" settings of the files - I just need to backup the files only. I would like to back the files up for a year or two and I am concerned that in the future I may not remember my usernames or passwords to access these files from the burned DVD.
Do "ownership & permissions" apply to files burned onto a DVD? Or does the DVD burning process erase the "ownership & permissions" settings? I tried to burn a DVD from OSX by creating a burn folder and I didn't see any setting that allowed me to remove the "ownership & permissions" settings.
Thank you for any insite into this.

Thanks Mulder,
Here is what I am trying to do:
I do not need to backup any system files - I already have OSX on my original DVD if I needed to re-install. I only need to backup the users' document files and maybe some email folders in the users' libraries.
I set up three accounts:
1. The first account is for admin purposes only.
2. The second is for my own use - it is the account used most often on this computer.
3. The third account is for my family.
Note: I will set up a fourth account for our student renter later.
I will have access to the user names and passwords of all these accounts in case I need to go into the accounts to back up their documents. But the user(s) of the family account will not have my password - so the kids don't accidently erase any of my files.
When working in the second account (which is used most often by myself), I sometimes need to place newly created files into the "document" folder on our family account (the third account). And so I purposely changed the "Ownership & Permissions" on the "document" folder on our family account (the third account) to Group: second account. This allows me (the second account) to place files into the "Document" folder of the third account (the family account). After doing this, I also need to change the "Ownership & Permissions" of any added files to Group: third account so the user(s) of the family account can edit (read and write) the files I add from the second account.
An alternative setup that I decided not to use: I could have made use of the "users/shared" folder for this, however, I do not want everyone to be able to access these files - especially when I set up a fourth account (or even more accounts) in the future. I only would like to share the contents of the third account's "Document" folder between two users (user of the second account and the user of the third account).
Now I will continue the explanation of my setup:
Over time the "Document" folder of the third account (the family account) will become filled with a mixture of files with different Ownerships - some created from the second account and some created from the third account - but all editable from either the second account or the third account by assigning each other access via the "Group" designation in "Ownership & Permission". Because of this mix of files with different ownerships, I could, if I wanted to keep the settings consistent, select the "Document" folder of the third account (the family account) and change the ownership of all enclosed items to the user of the third account by using the "Apply to enclosed items". I would probably also change the "Group" designation to the second account too.
I will be able to make all these changes because I have the user names and passwords for all the accounts.
Now here is my main question:
My concern is that when it comes time to backup the document folders onto DVD, what if in a couple years I forget these passwords? You see, I would rather not copy any "Ownership & Permissions" settings of the files onto the DVD. Lets say that in a couple of years I go back to my DVD backup and need to pull off some old jpeg files and put them onto my computer. When I insert the old backup DVD will it say: "Sorry, you do not have access priviledges to view these files" or something like that? That would be a real problem. These are my own files. Why would I want to risk making an important backup DVD un-useable in the future because of some long-and-forgotten permission settings?
What I would like to do is copy all my files onto DVD for backup in such a way that "Ownership & Permissions" are not copied. Why put the risk of a limitation on your important backups? Is there a better way to do this? What do other people do?
Am I making this more complicated than it has to be? As you can tell, I am a beginner with OSX (and permissions) and I am looking for some advice. Thanks
Mulder, when you wrote:
"If you're trying to backup just selected files, such as your purchased music or applications, etc., then ownership and permissions shouldn't be a problem."
did you mean that ownership and permissions are not copied? That would be great. But I am not sure if that is what you meant to write. Thanks!

OS X extern drive ownership/permissions and NFS exporting

- I have an external (250GB) firewire drive on OS X 10.4.9.
- I want to have it available to local users of this Mac but with ownership/permissions of created files/directories protected in the usual UNIX sense of unique UID/GID -- files/directories created by one user cannot be read/written by other users of this Mac except as allowed by standard UNIX permissions groups settings; eg., those set with 'chmod' command.
- I want to NFS-server this drive volume to a linux NFS client (eg., RHEL 4), again with files/directories protected in this same UID/GID UNIX sense. In our case, the users' UID/GIDs will be made to match, but regardless, I wish likewise for file/directory use on the linux client to be restricted as per UNIX permissions and the files/directories created by the Mac users have protections remain in place against linux user access, and visa versa, as above.
Is this feasable in Mac OS X (without OS X Server)?
How does one go about acheiving it?
I have basic Netinfo Manager skills for creating NFS exports and starting NFS daemon services, but am not expert on all available export options. I have average linux IT NFS server/client and user management skills.
Thanks,
-Neil

I don't know about networking with Linux, but I don know that for OS X users, enforcing permissions on an external drive without OS X Server is tricky.
First, log in to your admin account. Right-click the drive, Get Info, expand Ownership & Permissions, and uncheck "Ignore ownership on this volume". Then set permissions accordingly.
The problem is that any unprivileged user can log in to his own account, Get Info, recheck the box, and get ownership of the entire contents of the drive. This is possible even without the admin password.
There is a workaround that will remove the Ignore Ownership box from the Get Info panel so that there will be no box for them to check. First make sure that the box is unchecked and that the permissions are set how you want. Then enable ACLs on the volume by entering this command in a Terminal window:
sudo fsaclctl -p /Volumes/volumename -e
Then restart Finder. Now there's no box for the unprivileged user to check. But I don't know where this setting is stored; perhaps the unprivileged user can find some command-line way of getting the box re-checked and thus getting ownership of everything.
If there is some way you can get the data off of the external drive and onto the main boot drive you will have the best chance of keeping the data safe.

Wholesale fixing of ownership & permissions

In previous attempt at transferring a whole disk of data, somewhere in the process the ownership & permissions of certain folders got set so that I can only read the folder. Others are set correctly.
This is a minor problem, but at least once a day I have to manually correct a folder's ownership & permissions settings.
Is there a way to fix all the folders at once??

Open the Terminal in the /Applications/Utilities/ folder, and enter the following:
chmod -R u+w (drag the folder containing all the transferred data here)
Press Enter, and the account listed as the owner will be able to write everything inside this folder. Other solutions are available if you get an Operation not permitted error from the command.

Access permissions on HDD connected to Airport

I have a new Airport Extreme wirelessly connected to my network. I have two HDD connected to the Airport, one for Time Machine, the other for my iTunes library. No problem with the HDD used for Time Machine, but on the other HDD the access permissions keep resetting to 'Everyone' being given no access. When I go in and change the permissions, close the information box and open it up again it has reverted back to no access. If I reboot the laptop it will normally fix this, be fine for a bit and then happen again.
Any ideas why the access permissions keep changing and what I can do to stop it happening?

Unfortunately, Apple did not leave much room for setting user permissions for AirPort Disks. As you know, you can choose from one of three methods, but regardless of which method you choose, you cannot set permissions individually for folders/files on a drive, nor set them differently on either a different partition on the same drive or across multiple drives attached to a USB hub.
What you are experiencing is possibly a shortcoming with the AirPort's file sharing feature. Even with the "With Accounts" option, there is inconsistency between partition vs. accounts. With multiple partitions, formatted with HFS+, you do not have any control on where the user permissions account folder ends up. Also, the location of this folder seems to change arbitrarily so that even something as simply restarting the base station will change which partition has this folder and subsequent permissions ... with the other drive getting the "Everyone" permissions ... like you are experiencing.

I have 2 sets of permissions, how do I delete one?

I have five Macs, one G4 and 4 - G5's. G5s are running Snow Leopard 10.6.8.
Five graphic designers, who back up their work on a Mac XServer 10.6.6
Permissions on the designer's Macs are set to read/write for everyone.
Designer A backs up his job to the XServer, then Designer B needs to edit it, so she attempts to pull it off the XServer.
Permission denied for only some of the files, not all.
I guess I need some guidance on the proper way to administer the ACL on the Xserve.
I have set up an ACL group on the server. The strange thing is, there are 2 sets of permissions showing, one seems normal, but the other is labeled "Custom".
Is there any way I can log in as something other than the Administrator, and "wipe out" the custom permissions?
I usually do not mess around in the Terminal.
Thank you for any insights...

As Templeton Peck says, the proper way is to use the repartitioning facility, but this will result in loss of data.
However, SubRosaSoft do make a utility, Volume Works ($10), that will do this resizing on the fly. A complete back up would be prudent in either case.

Settings>Store (or iTunes & App Stores if you are running iOS6)>Apple ID. Tap your son's ID and sign out. Sign in with your ID and password.
You shouldn't lose the music, but if you try to update any apps that you bought with the family ID, you will have to use that password that is linked with that ID in order to update.
Avoid downloading past purchased content with the old ID if you can since you will associate the iPad with the old ID for 90 days and you will lock yourself out of your own, new ID for that period of time. Read more about associated devices in iTunes here.
