Permissions for files saved on another machine's shared disk

I'm having problems with permissions on files that I create on my Macbook but save on my Mini. They are all created as read only for everyone except me, which rather defeats the purpose of having the shared directory on the Mini. I want to change the default permissions, but I can't even change them on a file by file basis - it simply doesn't allow me to change "everyone" to read & write. Really, changing the default will do, but I can't find where to change that. Can anyone point me in the right direction please?

Is it possible to reformat the disk with other filesystem, like HFS?
The drive will always be mounted as FAT32 when inside the Time Capsule because of the method used to mount it. Click here for more information.

How to organize variables for file saving and scalability?

Hello,
I have created several CVI applications that store production data for numerous machines. To organize the data for file saving I have implemented structures. This has worked well with one limitation, the inability to scale the structure at a later date without invalidating existing files. I would like to consider alternative approaches that would allow scalability.
Here's an example of my current method...
// Definition of structure per machine.
struct machine_1
   int int_param_1, int_param_2, int_param_3;
   double dbl_param_1, dbl_param2, dbl_param3;
struct machine_2
   int int_param_1, int_param_2, int_param_3;
   double dbl_param_1, dbl_param2, dbl_param3;
// Definition of inclusive structure. (Member name and structure tag name are the same.)
struct
   struct machine_1   machine_1;
   struct machine_2   machine_2;
} machine_parameters;
To assign a value to a structure variable:
// Assign value.
machine_parameters.machine_1. dbl_param_2 = 77.47;
Then when it comes time to save the populated structures:
// Save structure.
error = fwrite (&machine_parameters, sizeof(machine_parameters), 1, dest);
The problem comes later when multiple files already exist and one of the machine structures needs an additional variable added. For example, if I need to add int_param_4 to the machine_1 structure. Adding this variable will invalidate the previously saved files because they were saved with a different structure and will not be able to be opened with a new structure containing one additional variable due to the structure definition mismatch.
I have added spare variables per data type to the structures for each machine, but it's a losing game. If I add 10 spare variables, I end up needing to store 11 more pieces of data.
Is there a better approach?
Thanks,
Aaron T.

One simple way is to output the data as ASCII comma separated values, with a newline character at the end of each row of data.
I.E., the only structure to your file data is a "row" of CSV's, with the file containing some number of rows.
Then, you load the data into Excel, and it will parse the CSV's for you and when it sees the newline, put the next set of CSV's on the next row of the worksheet.
If you ever need to expand the number of items in a row, you just add them as you generate data, pushing the newline to the right, the extra data extending the row.
So you get an Excel worksheet filled with rows of (possibly varying length) data.   So long as you add data at the end of the row when you redefine what you're saving, anything reading the file should see the same stuff that was always there.
You can write a macro to reformat or parse the CSV's once they're in the spreadsheet. With Excel 2007 supporting very large worksheets, you can put a lot of data into one. I think they expose a C interface for writing fast data manipulation of cell data now too - sort of a fast macro from the Excel viewpoint. I think the number of columns is 16384 and 1 million rows in a "Big Grid". The Excel 2007 engine is multi-threaded and you can tell it how many cores to use on a multicore machine.
So the only problem I see is the loss of local structure (your C structs get serialized and get concatenated to one another) but you could re-introduce the structure with a macro.
Or, if you were to write out serialized binary values and then view the file data using a hex editor like Neo, you can tell Neo what your C structs were and it will pick up binary file data and put it back into the C structs for viewing.
Or use MatLab to read the CSV's and reformat it.
Or use the CVI SQL interface and write it out as database records. I think the SQL toolkit costs extra, maybe it comes with the FDS.

V10 Default Settings For File saving

Hello, Could someone please tell me the default setting for file saving options in preferences for Elements V10 ?
Thank you.

If you reset the Preferences, all preferences will be set to their defaults: Hold down your Ctrl+Alt+Shift keys when launching the Editor and answer "Yes" to the prompt asking if you want to delete the Preferences. They will be re-built.

Can I access files copied to this machine in target disk mode from this machine?

Can I access files copied to this machine in target disk mode from this machine?

HI Claire,
YOu didn't indicate which Mac OS you are using so I'm going to assume 10.4.x.
Connect the FireWire cable to the target computer after starting it up in FireWire Target Disk Mode.
*If the cable was already connected, unplugging it from either computer and plugging it back in should allow the target computer's hard disk to appear on the host.*
Also, make sure you have the most recent Firmware for your iBook... go here:

Is there a way to save project and all media for easy opening on another machine?

So is there any way of instead of just saving the project and your computer locates the media, can you easily save a project and all the media in like a zipped folder so you can open on another machine?
Thanks

How do you change the default permissions for files?

I have all my users saving (via AFP) to an Xserve RAID, I am using ACL to control who has access to certain area.
This is fine when moving files in the finder, all ACL are respected, however when saving files from Photoshop it ignores the ACL's.
So if user A saves a file they become the owner- which is fine, but the group and everyone permissions are read only, so when user B ammends the file they get a permission warning when they try to save, the work round I'm using is to trash the file just before you try to save- not ideal cos if the save fails you've lost the work.
What I would like is for the default permission to be group "design" Read and Write and leave everyone as read only
So when any designer goes to oversave a file in photoshop they can do.
I needf to leave ACL's on as they are working well in every other situation, i.e I have certain folders set so once images have been added they cannot be deleted or renamed by certain users.
It only seems to be Photoshop that gives us this problem, Quark files and other docs are able to be saved according to the ACL

Hi
There are some important distinctions and points to be made here.
POSIX Permissions are always set for every file and folder. ACLs are optional for any file, folder or share point and work IN ADDITION to POSIX Permissions. SACLs (Service Access Control Lists) are optional for specific services such as AFP, FTP, SMB, Mail etc and are independent of files and folder as well of standard POSIX Permissions and file system ACLs. Allow access is cumulative and Deny access is first match.
ACLs supersede but don’t necessarily override Standard UNIX permissions.
The best way to use ACLs is to enable Access Control Lists on the desired volume, create the share point folder from within Workgroup Manager, define the Users and Groups and then drop the relevant User and/or Group into the ACL window and define access privileges from there. Don’t be tempted to use the Standard UNIX permissions in addition to ACLs as all sorts of problems can ensue.
Privileges and access can quickly get confused and share points can be broken. Deny settings defined in ACL take precedence over all other privileges settings. Deny settings defined using Standard UNIX as well as ACLs can, in some cases, mean share points becoming inaccessible to all users even those with administrative privileges.
Wherever possible try not to set access privileges using the Finder.

How to set permissions for files created by Windows on OS 10.8 volume

I am in process of upgrading from an iMac with OS 10.6 to an iMac with OS 10.8. In my office network, I store all files on my iMac and let the Windows PCs act as workstations to read/write onto the Mac. (It's simpler to have all files centralized in one location, and only have to be concerned about backing up one volume.)
When I had OS 10.4 and OS 10.6 any newly created file saved by the Windows PCs onto the Mac could be opened by the Mac.
But with OS 10.8, I can not open newly created files from Windows. The file permissions for the newly created files from the Windows PCs are:
PCUser = read/write; Everyone = no access.
What do I need to do so that newly created files from the Windows PC (currently Windows 7) can be opened by the Mac, without having to use Get Info to reset the permissions each time?

You could try adding this Access Control Entry (ACE) to the folders you let them save to:
sudo chmod -R +a "accountinggroup allow delete,chown,list,search,add_file,add_subdirectory,delete_child,file_inherit,directory_inherit" /Path/to/topmost/folder
You first need to create a group for all the sharing people you want to have access to that folder, if you don't already have one. In the example, "accountinggroup" is the group, so change that to whatever you want to use.
The ACE allows them full access to the files in the folders. If you want to limit that, remove the option (such as delete).
You create Groups in Users & Groups System Preference just like creating a new user. Just change the account type to Group.
If you want a GUI to do the settings, try Sandbox. It's got a few glitches in the Interface, but it seems to write the ACL correctly. One glitch is selecting the Group or User. I had just a list of Continuing in the popup menu. I typed in the Group name I wanted and it worked. Some errors pop up as you traverse the file hierarchy, but you can dismiss them.
Here is an old hint, which gives a little background, and some other options: http://hints.macworld.com/article.php?story=20090219133314985
The Server tools would allow you to set this up more easily, but if this is all you need as the server, I don't know if it is worth it.

Permissions for file sharing to Windows users

Greetings, I would be very pleased if someone could help me with file sharing permissions for Windows users of a Mac mini file server running Snow Leopard 10.6.1 (not server).
I have a folder in my root directory, lets call it Project, that holds a series of 10 sub folders, say 1 through 10. Some of my users I wish to have read/write access to the whole Project directory, and, having enabled file sharing in System Preferences (and SMB for Windows), I did cmd to get info on the Project folder, ticked sharing, added the users (whose user accounts I had replicated on the Mac from their Windows machines), gave them read/write access, and then was able to map a drive to Project in their machines. All good so far, notwithstanding an hour tussle with a Vista laptop . The other user 'groups' were set the following permissions: me - read/write; Admin - read/write; Everyone - no access; which seemed sensible.
Then, when I wanted to only share say sub folders 4, 5 and 6 with other users, who will not have access to the whole Project directory, things were not as straight forward. I followed the same procedure as above, but for the particular sub folders. However, I think they are only able to see them if I provide read or read/write access for Everyone to the parent Project directory. This of course then lets them at least see all the other folders I do not want to share with them. I don't seem to be able to remove the Everyone group from the Project directory, which occurred to me might resolve this.
Any thoughts? Thanks.

"On the way down, it seems to me that you still can prevent that user from using folders that he or she is not supposed to use by setting appropriate permissions."
I don't think this is the case. If I allow someone read & write access to a folder because they need to have read & write access to two of three subfolders, I cannot deny them (at least) read access to the third folder.
In respect of a particular folder:
1. You can only assign read; read & write; or write (drop box) to an individual user; and
2. You can only assign No Access to everyone.
Do I need to use Snow Leopard Server to be able to assign No Access to a particular folder for an individual user?

Help. Photoshop CS5 files saving in another format?

Ok,
So I'm using photoshop in CS5 to animate, but I'm coming up with a saving problem. I am saving the file as a PSD, but when I go to open the file the next day to keep working, its saying that the file is not compatible with my version of photoshop. I only have CS5 and I am not changing the file type when I'm saving, I always save as a PSD. Can someone shed some light on why this is happening? Its incredibly frustrating as I keep losing my work. I've lost about 10 seconds of animation due to this, so far, and if anyone actually animates traditionally, you will realise just how much work this is. Please, please help, its really getting me down.

Have you tried saving as another layer-capable format, tif or psb?
Is there anything notable about the files – extraordinary number of layers, size or whatever?
Other than that have you performed the usual trouble-shooting routines (trashing prefs by keeping command-alt-shift pressed while starting Photoshop, 3rd party plug-ins deactivation, system maintenance, font validation, etc.)?

How to restore a file inside an encrypted sparsebundle file saved in time machine

Hi,
On Mac OS X 10.6.6, I use an encrypted sparsebundle file to save sensitive corporate files (not using the Filevault built-in feature), mounting it and using it as a folder.
The sparse bundle is in my Documents folder which is part of my Time Machine backup.
Unfortunately, timemachine doesn't actually see what's inside the sparsebundle file and can't restore only one of the files from it.
I always have to restore the full sparsebundle, which is 34G as of now...
Is there a way to let timemachine index and store the content of the encrypted sparsebundle, without compromising the confidentiality of course?
What other completely different solution should I use otherwise?
Thanks.

Not a good sign. That's the message OSX sends when a disk image is corrupted. Can you restore the whole thing, and still see the contents?
It seems an external drive or partitioning the drive would be required, unless using sparsebundle files would do the same.
A separate drive or partition, each with different passwords, would probably work.
side question, it seems TM saved the entire modified files and not only the modified blocks. Does it behave the same for sparsebundles? it doesn't seem to copy my 34G file everytime.
Do you have a "sparse disk image" or a "sparse bundle disk image"? As I understand it, Time Machine saves the entire contents of a sparse disk image if anything's changed, but only the modified "bands" of a sparse bundle disk image (but only when they're not mounted).
If you use an encrypted HD or partition, it should work normally -- just saving the individual files that are changed, and allowing you to view and restore individual items.

Setting Oracle Permissions for file access from a pl/sql function

I have a pl/sql function that calls a java method which moves a
file from a directory to another.
Since we are using Linux, Oracle wants some permissions.
Those permissions are set using:
call dbms_java.grant_permission(USER, 'java.io.FilePermission',
FILE, permission)
OK, i want to use this in my pl/sql function, but it doesn't
work.
My function looks like something like this:
-- some pl/sql code
dbms_java.grant_permission(someUSER, 'java.io.FilePermission',
sourceFILE, 'write');
dbms_java.grant_permission(someUSER, 'java.io.FilePermission',
destFILE, 'write');
flag := move(sourceFILE, destFILE);
-- flag is for 1 -> done and 0 -> error
-- some more code ...
The problem is the lines of
dbms_java.grant_permission(someUSER, 'java.io.FilePermission',
sourceFILE, 'write');
do not work!
When i grant permissions manually in sql plus it works great,
but when i do it from the function it does not work!
Any ideas anyone?
Any help would be appreciated.

The command :
dbms_java.grant_permission
(someUSER, 'java.io.FilePermission',sourceFILE, 'write');
is right.
Open sqlplus
Connect as sys or system
type :
execute dbms_java.grant_permission
(someUSER, 'java.io.FilePermission',sourceFILE, 'write');
commit;
try to compile again your procedure...does it work now ?
bye

Permissions for files in /sys

Many files in /sys or /proc/sys are not readable (I get a "permission denied"), even as root. Now I do some experiment:
cat /sys/module/usbhid/uevent
cat: /sys/module/usbhid/uevent: Permission denied
and now:
[root@pcolivier /sys]# ls -l /sys/module/usbhid/uevent
--w------- 1 root root 4096 May 6 09:22 /sys/module/usbhid/uevent
[root@pcolivier /sys]# chmod a+r /sys/module/usbhid/uevent
[root@pcolivier /sys]# cat /sys/module/usbhid/uevent
cat: /sys/module/usbhid/uevent: Input/output error
There is something a don't understand in this. Normally we may read a file as root, whatever the permission of this file is (this is true for normal files). It seems here that the kernel enforces the permissions bits of the file in order to access it; without the read permission it denies access to the file, with the read permission it tries to read the file (and fails for another reason). My question how the permissions of the files in /sys are sets? Why they are enforced as root contrary to normal files?
Last edited by olive (2012-05-06 07:30:00)

The file /etc/ftpd.conf should have the line
umask all 022
in it somewhere. This will cause files to be created with permissions of 644 (rwxrw-rw-) and directories to be created with permissions of 755 (rwxr-xr-x).
For more info 'man ftpd.conf' in the terminal.

Boot camp files saved to time machine

I have recently made the change to mac, however alot of programs i need are only available with windows operating system. If I were to use boot camp to run windows and use the programs i need, after saving those windows files will they be saved to my time machine, since i am still running it on my imac?

Hi and welcome to Discussions,
in addition to Niels post, WinClone http://twocanoes.com/winclone/ is an OSX application which can make image files of your BootCamp Windows for backup.
Placing these image files on your OSX partition will get Time Machine to backup this file.
A Windows backup program to have a look at is Casper http://www.fssdev.com/products/casper/ but that needs to have an additional Windows file system (NTFS) partition on your external harddisk as destination for the backup.

Retreiving files saved with Time Machine on a different computer

I am trying to view files on my external hard drive that I saved from my Macbook Pro on an older Macbook that does not have Time Machine on it. Any folder I try to open is locked and I get a message saying it is empty. When I checked the backups on the original computer, they work fine. Is it possible to view these files on a different computer?

An older MacBook that doesn't have Time Machine would not know about hard links to folders. So, when you look in them, you don't see the linked files and thus it looks empty. TM uses hard links to keep track of files that have not changed. Somewhere, there is an actual file, but if it doesn't change, TM just puts a hard link in all the subsequent backups. Trying to dig through the backup, especially after changing permissions on the folder, will likely destroy the backup.
Perhaps one of the Finder replacements or Time Machine helper apps can understand the hard links to folders, but I'm not sure.

Set Permissions for file deletion

I need to create a new temp directory and at the end of my program, I need to delete the temp files...pretty common thing to do. My problem is the permissions dont allow me to delete the files unless I set them first somehow. I want to know what the settings must be in the Set Permission.VI so I can then delete the files. How do I mechanize this?

Are you having this issue in both the Development Environment and the Run Time Environment? The second solution that I linked is for executables only, and only makes it so that you don't have to turn off the UAC because it has administrative privilages. Anything that an administrator is able to do, the executable will now have permission to do. To test if this solution will work at all, just right click on the executable and select "Run as Administrator". If you are still having issues when the executable is running as administrator, the above solution will not work.
Try running this snippet and let me know what happens. All it does is create a file in the temp directory, read its permissions, then deletes the file. This runs on my computer with no error in the Development Environment and has the permissions of binary 110110110 (Decimal 438).
