Nm-applet permissions problem?

After i've upgraded to Gnome3 (the reason why I post this here),
my previously working nm-applet has gone mad. As I try to change settings,
either from the panel applet, or from the control-center, it doesn't accept
any of the changes.
I've tried to launch it from a terminal too, no error message is shown.
( $ gnome-control-center network )
And here comes the best: after changing the settings, I've a REALLY FAST popup window showing up:
"System policy prevets users to change network settings", or something like this -
(I've managed to read this by breaking my fingers on the PrintScreen key).
In short, it asks for the root password, but I don't have the time to type, it disappears.
1, my user is part of the network and networkmanager groups ( see wiki )
2, if I launch "#gnome-control-center network " as root, the checkbox "accesible to all users" is well checked,
    root is able to change settings.
3, I've crated another user, same promlem, not able to change anything
everything worked 'til Gnome3 has arrived (besides of this, I like it... and that is just the beginning)

# ps ax | grep polkit
3519 ?        Sl     0:00 /usr/lib/polkit-1/polkitd
And I've temporary "solved" the problem by editing "/usr/share/polkit-1/actions/org.freedesktop.NetworkManager.policy".
At the "<action id="org.freedesktop.NetworkManager.settings.modify.system">" changed the line:
<allow_active>auth_admin_keep</allow_active>
to
<allow_active>yes</allow_active>
But I really don't like this solution, I mean there are other users on my system too, I don't want them to change my settings.
So, this is not a solution

  • A Java security or permissions problem?

    First of all, I don't know much about Java, even its naming and version numbering nomenclature, and second, if there is a better group to ask this in, please let me know.
    System is Mac with 10.4.4. I have Java 1.3.1, 1.4.2, and J2SE 5.0 (1.5.0) installed. The Java preferences application lets me choose J2SE 5 or 1.4.2 to run applets via a browser. The problem happens in both settings.
    The problem is that we have a printer that serves a little Java-based management application to view history and otherwise manage it. When I hit the IP, I get the Java coffee cup for a few moments, then a blank area. It fails in both Safari and Internet Explorer.
    I'm pretty sure this used to work in OS X 10.4.3. It works from Windows which has runtime 1.4.something.
    In the Java console, I get the following. (I've snipped some lines.)

    This appears like a permissions problem, but I've fixed permissions several times.
    Any idea what the problem is, and is it fixable from my end?

    Problem has finally -- over a year later -- just gone away.

  • Fixing permissions problem on Mac OS that impedes start of Adobe applications

    See this article for a suggestion for how to deal with a cause of After Effects (and other applications) taking a long time to start on Mac OS:
    fixing permissions problem on Mac OS that impedes start of Adobe applications
    This same issue also affects the functioning of Dynamic Link and warnings regarding QuickTime not being installed.

    "Later I used DirectoryChooser. This is working fine but the pop-up is always coming behind javafx applet when started in browser. Note: This is working fine if we run as stand alone applicationYou should file a bug/feature request about this against the Runtime project:

    Exception in thread "AWT-AppKit" java.awt.HeadlessExceptionSee:
    http://javafx-jira.kenai.com/browse/RT-20784 "Mac: Headless environment issue, MacOSX"
    The above issue discusses some potential workarounds which may (or may not) work in your situation.
    Try the latest 8-ea build (available at http://jdk8.java.net/download.html).
    The graphics environment is no longer forced to be headless in the java 8 trunk (the jira case I linked is closed as fixed), but it may take a week or two for the fix to propagate to the jdk8 early access download page.
    Also note that this kind of call from a JavaFX application to a Swing component isn't really a supported configuration (embedding JavaFX in a JFXPanel in a Swing application is supported, but other forms of interaction between JavaFX and Swing such as JavaFX opening Swing dialogs are not). That's not to say that it might not work, it's just that you shouldn't expect it to work now or continue to work in the future (especially in an applet deployment context where the window handling is more complex for the underlying frameworks due to the browser embedding). Further facilities to ease Swing and JavaFX integration are planned for JavaFX 8 (http://javafx-jira.kenai.com/browse/RT-12100 "Swing components inside JavaFX"), but I don't know if it would mean that the scenario you are trying to achieve would be supported.
    A further alternative you might have would be to deploy your application as a Swing application rather than a JavaFX application and wrap your JavaFX content in a JFXPanel. It is likely that opening a Swing JFileChooser would work in such a mixed code scenario, though I have not tried it.

  • My iMac 8.1 was slowing down and had permissions problems. I backed everything up, and then re-installed. Now all I get is a black screen. Power+D gives me a hardware error message: HDD-1336. Help!

    My iMac 8.1 (10.6.8 ) was slowing down and had recurrent permissions problems, mostly with Java. I backed everything up, and then re-installed from time machine. Now all I get is a black screen which says I need to reboot. Power+D gives me a hardware error message: 4 MOT/1/40000003: HDD-1336 or HDD-1327. When I reboot from the OSX CD and start disc utilities everything checks out OK. When I reload 10.5.2 from the OSX CD everything seems to work OK and no more permissions problems. But then I loose all my email and safari stuff. Anyone have any ideas short of going back to my old PC?

    No unfortunatley it's too old, you are referring to Target Display Mode which became avialble in 2009, your 2008 needs to have the HD replaced. I'd still do that if everything else is OK or you can simply buy a new MM and display or even a new iMac  or an Apple refurbished iMac to save money.

    I used Terminal to change the permissions on the folder in question.  I followed the instructions in this article:
    iTunes: Missing folder or incorrect permissions may prevent authorization
    In my case, the folder was there, so I needed the command to change permissions on the folder, not to create one.   I was hesitant to use Terminal b/c I know that if I made an error I could wipe out my hard drive or render my computer unusable.  So to be SURE I didn't make an error, I carefully copied the command from that page and *pasted* it into Terminal.  Also, before I could do anything in Terminal, I had to go change my admin password (it had been a blank password before and that's not acceptable for making changes in Terminal).  I was just super careful when entering my password or doing anything else while Terminal was open (making sure I didn't accidently hit the spacebar or another key, etc.)  And it fixed the problem right away.
    What was confusing for me was that the iTunes error message said to change permissions in the FINDER, which is what I was trying to do.  It didn't mention Terminal.  What would really be helpful is if Apple included a link to a page like this in their error message.

  • Disk Permissions Problem on External HD Accessed Wirelessly

    Hello,
    I recently purchased a LaCinema Connect MiniHD and have been using it with a Western Digital 750Gb drive (formatted Mac OS Case Sensitive, non-journaled). I also recently bought a D-Link DWA-125 wifi dongle to use with the LaCinema.
    I can access and read/write to the drive without problem when it connected via USB to my computer or to my wife's laptop. However, when I try to trasnfer to it wirelessly over the network (i.e. when the drive is connected to the LaCinema which, in turn, is on the network) I receive error messages when I attempt to transfer files to certain folders (including the "root" folder). What is interesting is that the folders that I can transfer to appear to be ones that were created on my old work computer, with an earlier OS version (definitely not Snow Leopard).
    I suspect that I have some sort of permissions problem, but "Repair Permissions" is not available to me for this drive in Disk Utility.
    I have plugged in the drive into my computer and have reset the permissions so that the "owner", "staff", and "everyone" are able to read and write for all folders and sub-folders, but it has not solved the problem.
    Any advice would be greatly appreciated.
    Thanks,
    Graeme.

    Eric,
    I, too, apologize for the delay in posting. I have been away from the discussions for a rather extended period.
    Well, any NTFS formatted volume will only be accessible to you as read only. No, this is not something new, but has always been the case. To make matters worse, I have heard that Windows no longer provides any way to create a FAT-32 volume; one must use OS X to format the volume or use a third-party application in Windows. This information may be incorrect, but I wouldn't be surprised if it is true (we're talking about Microsoft, here).
    If you can copy any data on this drive to some other location, then use Disk Utility to format it as FAT-32, the data can then be copied back and it can be used to transport the data cross-platform, with read/write access on both ends. Is this a possibility for you?

  • HT2963 How can I fix permissions problems now that I have changed permission on my HD and have error code -8076, locked disk or ....?

    iMac v10.7.4. Error message says disk is locked. Permissions set for read/write admin (me). Can't open iTunes, Mail, photoshop, adobe bridge [you do not have permission!]. Fonts in Word are unexpected, not cambria. Used Disk utility to repair permissions (ran it twice, once before reinstalling photoshop from DVD; once today). Situation worsening.

    Permissions problems occurred after I downloaded Lion update on 6092012. I believe the  problem originates with  Lion (see the 19 pages of posted problems in the community). I have now talked with Apple Support rep and an Apple Genius. Have reinstalled Lion from the HD Recovery disk. I see some improvement but also at least one  new problem: TimeMachine apparently has lost all backups, don't know how or why. Will have to take machine to a mac specialist or wait for Mountain Lion to arrive. Lion is a bad cat.

  • New SSD, but LOTS of Permissions Problems

    I have installed a new SSD drive alongside my 1.5TB spinning drive on my 24" 2009 iMac 2.93GHz. I used Carbon Copy Cloner to move my everything except my User account over to the new 60GB SSD.
    I originally assigned the User's folder on the old drive using the Users & Groups User/Advanaced Options window to change the Home directory, but that resulted in unrecoverable crashes and I had to reinstall the OS three times until I finally left my old files on the old drive and just ran my Applications on the new drive, keeping everything else on the old drive, but not connected as a "user".
    However I've run into a ton of permissions problems with every file I open and many programs that access thos files and have done this so far to fix it:
    Run resetpassword on both drives in terminal when I rebooted to the Mac OS X install disk (Lion).
    Run Drive Genius' repair permissions utility.
    Run Disk Utility's repair permissions.
    I continue to have issues with every file I use on the old drive, so I'm at a loss to fix this in place. I did read somewhere that moving your files to another drive, then reformatting then moving back can by default fix any permissions issues, so am considering this as a fix:
    Move files on the old 1.5TB drive, folder-by-folder to an external drive.
    Reformat the "old" internal 1.5TB.
    Recopy everything on that external back on to my 1.5TB drive.
    Run Repair permissions on both drives.
    This isn't fast or elegant, but I want the issue fixed. I don't want to have to open "info" on every file I use and check and change every file permission before I can use it!
    Any input on whether or not this is a real fix or is there a better one?
    Thanks!

    May not have anything to do with your issue but often
    the master disk image loaded on your hard disk before
    it leaves the factory has old (and/or odd) bits of
    code on it. Plus the transfer is done as fast as
    possible. Last they do not zero and erase the drive
    before putting the image on it, so if there are bad
    sectors they may not be marked as such and may be in
    use (& corrupted).
    As you are having trouble get your data off as best
    you can, erase AND ZERO the drive, repartition, and
    only then re-load from your Install DVD.
    Takes extra time but better safe than sorry...
    Well, I have no real means to do this now as I sold off my G5 already
    Also, how do you zero it?
    When I reformatted my G5, I picked the option to wipe and reinstall, yet when I did, the drive name and bluetooth names were still my old ones! - Not encouraging.
    In any case, its clear I have a software problem, so looks like I'll need to burn a zillion dvds and start over .
    Thanks.
