Locking access to folders

Hi
I am wanting to lock some folders, so that other users on my localised network can't open them. I have tried changing the permissions to: everyone > no access but when testing they can still be opened. is there anyway to do this? any help would be great!
Thanks

wierd. Noone should be able to get into your home directory, even with admin rights. They should see a the red 'wrong way' traffic sign superimposed on your home folder(s).
Open the users control panel, select the user accounts, and verify they are standard, not admin.
Is it possible an administrator, for whatever reason, has checked the "ignore permissions on this drive" box (seen when you do a get info on the drive icon)?
And you have already selected the folder, made your account the owner, and changed everyone else to "no access"?
While most security changes are instant, you may have to reboot the machine, or at least make the other users log off and back on.

I accidentally locked my desktop folders , unable to open them Ho two unlock the folders

You have done something which change the permissions and your user is not able to access anymore. You can play around and try to correct permissions manually by going to your home folder, right click on the Desktop folder and choose get info and when new window will be open, at the bottom of it, check if your username is listed and if has Read & Write permissions.
Other option is to boot to recovery mode (after starting up your computer press and hold CMD+R), then from top panel click on Utilities and choose Terminal. Once terminal is open, type in it resetpassword and when new window will be open, select Macintosh HD as your system drive, select your password and click on the RESET button which is next to "Reset home folder permissions and ACL". NOTE: do not reset your password, you don't have to.
Second options would be better in case if permissions on other folders been changed too.

Cannot Lock Permissions for Folders Anymore

This is something that just started happening: When I go to Finder/Get Info to change permissions on folders, the permissions are open, i.e. I don't have to enter my administrator password any longer to change them.
The padlock at the bottom right corner still shows locked, but the permissions are open. When I click on the locked padlock, it then asks me for my password, I type it, it accepts it, but then nothing changes...I can still change the permissions and it doesn't lock them.
What could have happened? When I went to Finder/Get Info, the folders were locked and I used to have to enter my administration password in order to make changes.
Any help would be appreciated.

Is creating a new user account a viable way of fixing this? Doesnt seem like its really fixing anything, just burying the problem. (No offense at Ebecks reply!!)
It is. The fact that you don't have any problems when you are using a different account also confirms the diagnosis - you have some corrupt/conflicting preferences files.
Two ways to deal with that: bury them or kill them - it will accomplish the same thing! user preferences files affect one user account ONLY and can not possibly interfere with your work if you switch over to a different account.
However, this might not be necessary. As I said before one way to deal with it is by using TM to restore your system to some time point before the you installed these extra programs and before the problem occured.
Another way is to try deleting some preferences files to see if that fixes the problem. The most obvious files to try are com.apple.desktop.plist and com.apple.finder.plist in the mainusername/Library/Preferences directory.
Since you can't delete them in the usual way as you can't access your folders do this:
Type "terminal" in the spotlight window and press enter. This should bring up a terminal window. type "cd Library/Preferences" (don't type the quotation marks) and press enter. Type "rm com.apple.desktop.plist" press enter. Type "rm com.apple.finder.plist" and press enter. Restart.
Hopefully, this will fix things.

Locking access to serial ports

I have two instruments on serial ports, and two independant VIs to control them. One VI may be running, or both, at any one time. The VIs may be running under LabView, or executables.
I would like some simple and elegant way of ensuring that when I run the second VI, it cannot access whichever port is being used by the first VI. I have experimented with using the VISA Lock Async.vi, which should do exactly that. However, it seems to be possible to have two VIs lock access to the same port, without generating an error. I can only assume that the "lock" is for the application (LabView), not the VIs.
I have looked at the synchronisation functions for a solution, but I can't see any reasonable way of using them. Semaphores are ok if you want to control access to a single port, but not the undefined list of ports that may be available on any given machine.
I could use a global array variable containing a list of ports in use. Not very elegant though...

Thanks, guys, but I don't think you have understood my problem. Read the first sentence - 2 completely independant VIs, and 2 or more ports...
I have written a program today using the globals option, which works very well. There should be a better way though.

ViLabWorks a écrit:
It isn't exactly clear to me why this is about one port. How much does one serial port cost versus programming time? Or even if it is about 4 serial ports the same applies. For me there is no question, doing something perhaps difficult versus spending next to nothing to solve the problem.
Well...
Sometimes you need to access the same equipement from different places in your application, or from different applications...
Usually I simply set/read a global "busy" boolean.
One problem I would like to adress is the automatic detection of specific serial hardware. How is it possible to find the port on which some equipment has been connected ? Of course, a solution would be to try to connect to this equipment by sending a command and waiting for the proper answer. However, before doing that, you need to detect the available ports (VISA Find Ressource), then scan each port after setting the proper baud rate, byte length, parity, etc..., then close the port to make it available to another application. Unfortunately, within LabVIEW, this procedure may interfere with other vis already connected to other serial equipments, with impredictable results.
Apart the solution proposed in my first post, I don't know a way of deciding if a port is already in use. May be I missed something ?

Cannot access shared folders anymore....

Hi,
We have a naughty problem at the office for accessing shared folders .
We use G5 Xserve + Xraid serving home access to 12 macs.
Our problem started when we updated all machines to 10.5.2 (nor did we have a problem with 10.5.1 or with 10.5.0).
All machines login correctly, fetch their folders with their home accesses located in the Xserve, as allways did, BUT :
·Almost all the machines running Leopard (except two) CANNOT access shared items. They get Error -5002
·The old machines running Tiger (G3 Imac's) acess shared items without problem.
So after many weeks doing multiple tests, we got the following conclusions:
·Problem is not server related.
·Problem si related to Leopard clients , although not in all
·Problem is not related to the machine, but with the account (accounts that can access shared items do it on any machine, and accounts that can't, don't do it on any machine)
·It seems that the trouble is related somewhat with Kerberos authentication, but it's not related to tickets (renewing them is no use)
·If we create new account with new name, it can access shared items
·If we create new account with same name that of the faulty one (renaming the later), it CANNOT access shared items.
We have got a problem in the office, and no clue of solving it.... Have read all over apple discussions over the internet, and although some people have similar issues, they are not as close as ours....
And none of the solutions proposed have solved the problem.
Any ideas would be greatly appreciated, cause we are starting to get desperate
Thanks everyone.

new update:
we are able to connect to remote shared folders with a different remote server (dual G4) from every machine
machines who can connect to local server are INTELs, the one who can't are PPCs
makes any sense to anyone?¿

Computer screen goes black accessing network folders

We have a computer on our network whose screen goes black when you try to access shared folders on the network.
When working locally it doesn't happen at all. But if you, for instance, open the run command and type in \servername and click OK it'll flash black. Or if you open a file in one of the shared folders on that server.
This is a new one for me. Any ideas on how I could begin troubleshooting? I've verified that the only time it happens is when accessing files/folders
shared on the server and that it only happens on that machine.

BO authorization model with sap roles / access tot folders, functionalities

Hi Specialists,
As authorization cunsultant in BI, I have little knowledge of the security setup in Business Objects.
I have to setup an authorization model were the authorizations are assigned via sap roles in the backend BI system. These roles are imported in BO were they can serv as 'user groups' and access to folders, functionalities.
Can anyone provide me a overview, guide, training document... on how the authorizations are managed in BO and best practice when they are linked to sap backend roles.
The goal will be to user the sap BI backend roles and user them to grant users in BO specific access to specific folders. Eg; User A can access folders 1 as "refresher only", User B is able to publish reports in folder 2, User C has only view access in folder 2...
Any help would be great!
Thanks very much in advance.

Hello,
this is the best approach you mentioned here.
I prefer to create roles serverd as functionalities in the Backend. For Example you have a "View" role, a "Refresh" role and so on.
On the other hand i saw some setups where there is only on role in the Backend with all the BO Users. Then you have to create you functional groups in BO and have to assign the Users there to the Groups.
Check the Adminguide of BO XI 3.1 for more Informations.

Access root folders in finder

Is it possible to access root folders in the finder window instead of using terminal

With the Finder active, from the File menu, select Find... .
In the Find window that opens, in the section under the heading "Search for items whose:", click the Name pull-down menu and select Visibility. The options in the next pull-down menu to the right will change accordingly; select either invisible items or visible and invisible items as you prefer.
You can make invisible folders visible all the time (not recommended) using TinkerTool
You can also make make .hidden things visible by Booting from another drive.
You can hide things selectively using AltoMac

Cannot access some folders from Bridge CS6

Only certain folders on my internal drive can't be accessed from Bridge.
I can access the folders from PS CS6 but from Bridge, files cannot be displayed.

Not sure where to look to ensure a folder is both read & write permission. Focusing on one of the folders which suddenly I can't access from Bridge - Pictures; if I use Finder all pics are visible from the folder. If I open a file from the folder in Photoshop I can edit and save in the Pictures folder.
Select a folder in the finder and choose cmd + i or use menu File / show info. This provides a window and at the bottom it shows the permissions that are set. If you are the user and have administrator privileges (meaning you you have access with password to the account and are able to install and uninstall applications) it should sat for both system and administrator 'read and write'
Only from Bridge are certain folders inaccessable....in Bridge the folder has a red circle with white - and message 'no items to display'
This is getting a bit tricky. If you have jpeg or raw files in the picture folder that also show in the Finder Bridge should display them without problems. If you try to visualize a library form iPhoto or Aperture this will not be able in Bridge because those files are packages.

Satellite A-300D and the general access to folders

Hello,
I can not open access to folders and files in control centre of networks and the general access. Earlier all was good, and now at attempt to open access to a file, after acknowledgement of the rights of the manager, occurs nothing - access is switched off. And at attempt to open access to the general folders writes "Server RPC it is inaccessible".
I think that an error in system.
How it is possible to correct?

Hello
Are you using your notebook at office?
If yes contact the administrator they can give you the rights to access the network folders.
Otherwise I think your firewall or security software is blocking the network access. Try to disable it and check it again.

Locking access to methods...

Hello everyone,
I hope somebody can help me with this tricky question. Basically, I need to lock access to other threads while the invoking method thread is executing.
Given the code below:
public synchronized string doWork() {
doSomeWork();
doMoreWork();
}Will the methods doSomeWork() and doMoreWork() also be locked to other threads, and if not how can I lock them until doWork() finishes?
Thank you,
Sergio Bastos

That is, both methods will be locked as long as
doWork is executing.No they won't, will they? Another thread can still
call doMoreWork. It just can't call it via the main
function.You can e.g. read on this link:
http://java.sun.com/docs/books/tutorial/essential/threads/monitors.html
"A critical section can be a block or a method and is identified with the synchronized keyword. The Java platform associates a lock with every object and the lock is acquired when a critical section is entered."
doWork has the object lock when it is executing, and no one else will be able to acquire that lock as long as the method is executing.

Locking access to email

Can I lock access to my email program, "Mail" and leave open the rest of my computer. This is to prevent anyone without a password to view my mail.

Not really a good way to do this. It would be better to set up a guest account and let others use that. Then you could "fast user switch" to the guest account for them leaving your account logged on in the background.

Time Capsule: Windows user could access all folders in TC

I have a new TimeCapsule (TC) 1 TB, 2 MBPs (latest Mac OS X) and 2 PCs - 1 runs XP and other runs Vista.
I had setup TC as NAS, allow users to access TC using account.
Each user in MBPs can access their folder and shared folder only, so it is fine.
Same for windows users, they can access their folders and shared folder only.
However I found that, if the windows user has the windows administrator privilege and has windows account password as same as TC disk password, then after logged-in windows machine, this user can access TC using Run:\\TCname then he/she can see all folders in TC and has read/write privilege on these folders. TC does not ask for any password (as long as the user has logged-in their windows machine) nor stop the user to access any folder in TC.
Is anybody has the same problem ? Or you can try yourself and see if it happens on your system ?
Apple: can you fix this, this is unwanted "feature" ?

SMB is blocked by every responsible ISP. As indeed it has to be due to the level of unprotected shares on computers on the internet.
If the TC is the main router.. and you have port forwarded SMB ports wan to lan.. be thankful your ISP has blocked it so your files and network are not hacked.
The right way to do this is a vpn router.. with the TC working as bridged device on the network.
Windows does not offer AFP which is the only other protocol Apple offer in the TC and is the only one exposed to internet.

Cannot access DFS folders as domain admin when using Server 2012 R2

Hello,
recently we added a new domain controller running Windows Server 2012 R2 to our domain. All other domain controllers are running Server 2008 R2. A user now had a problem with his home folder. Therefore, I logged into the new domain controller as a domain
administrator and opened an Explorer. Next I entered "\\ourdomain.comp\accounts$\homes" into the address bar. To my suprise I could only see one folder (the one for the domain administrator account). If I do the same on a any of the Server 2008 R2
machines, I can see all user homes (as expected).
I temporarily disabled ABE for the home folder and now I can see all folders. But if I click on any of them, I get an access denied error stating that I have insufficient permissions to access this folder. It does not matter whether I open Explorer as administrator
or not. On Server 2008 R2 it works in either case. I don't get what's going wrong. No matter which machine I use, I always end up trying to access the same folder on the same machine. Therefore, the rights on this folder are always the same and I should be
able to access it. Do I need to configure something on the new DC? Is there anything related to this that has changed with Server 2012 R2?
Regards,
Oliver

Hi Oliver,
According to your description above, here are the symptoms you observed:
•Logon Server 2008 R2 DC as domain administrator, you can see all user home folders under
\\ourdomain.comp\accounts$\homes and access these folders.
•Logon Server 2012 R2 DC as domain administrator, you can only see the domain administrator home folder under
\\ourdomain.comp\accounts$\homes.
•Logon Server 2012 R2 DC as domain administrator and disable ABE, then you can see all user home folder under
\\ourdomain.comp\accounts$\homes but get an access denied error when you access others user home folder.
Is there any error message in event log on Server 2012 R2 DC when you access the shared folder? Try to disable UAC on the server to check if you can access the shared folder.

Mandy
