Permission of system files

I see some system files will be having only write permission to owner,group and others.
Like ww--w- .
Whats the reason of giving permission like this to system files.
Anyhow we cannot open these files using vi or cat.
Then how can we write into it.

Do you have an example?

  • Kernel Panic from system file permission changes

    A friend and i were trying to share some image files with each-other so we firewire connected our two macs... (both mac book pros mine a intel core on snow-leopard hers the latest is7 operating system -prob Lion) when the corresponding computer did not appear on our desktops I entered "sharing" console on my system prefs and attempted to allow her computer to see and read/write mine... I got a pop up prompt asking if i wished to share all my internal files and I said "yes"  Shortly thereafter a repeat prompt kept popping up on my computer saying something like ~"can't share system files" I pressed "ok" each time it appeared and after a few pop ups it all seemed ok...
    By now as a backup attempt to share my files i had plugged in my external (open permissions) hard-drive which at this point suddenly told me i am not allowed to read or write on it... I ejected it and since the whole system was still spinning and wanting to share permissions I force-quit the finder and selected "shut down" my system to start fresh but when attempting to restart finder I first a few moments later I got that - multilingual kernel panic prompt
    it won't start up - it won't boot from disc (at start i hold down option and insert operating disc) it wont start up (I've depressed shift after start and arrived at a spinning wheel that never ends... i'm also out of my warranty and hoping to solve this without paying for a new mac

    Unfortunately, the log files are full of scary-sounding messages. Unless you have some specific problem other than the logs, there is usually no need to worry about it. Sometimes, a problem may be reflected in the logs, but you can't start with the logs. You'll never finish.

  • TS1717 unes, i have windows 8, i get the message, "the itunes Library .itl file is locked, on a locked disk, or you do not have write permission for this file.  how did this happen, how do i fix this?

    the message"The itun, library .itl file is locked, on a locked disk, or you do not have write permission for this file". i have windows 8. how why did this happen? how do i correct this and prevent another occurance?  I am able to access itunes on my i5, ipad, and my old i4 that i use solely as my ipod now. At the time  problem occurred, i was connected to ext hard drive that hold over 190GB music, to add to my library. I am now unable to add to my library using my laptop.  any advise/help is greatly appreciated!!

    I just had the same problem and was able to fix it after trying a couple of things I found after a search.
    The solution that worked for me:
    Find iTunes folder - it should be in C:\Program FIles (x86) or similar depending on your operating system
    Right click the entire folder (no need to open it) and click properties
    Click the security tab
    Click edit and highlight the user name under which you logged in.
    Click the box next to full in the allow column, which should check everything
    Click apply
    Open iTunes
    This worked for me.

    this may happen on external drives if:
    The external drive was hotpluged (removed) without going the correct "eject" way
    The iTunes library (database) got corrupted
    First Aid for external drive
    Close iTunes
    Unmount (eject) external drive the right way.
    Mount drive again
    Go to Workplace -> right click external drive -> choose "clean up" This will force the filesystem to rescan the file structure of the drive and rebuilding the file system table and journaling file.
    After the tool shows "done" (could last some time depending on size of drive) restart iTunes
    If your iTunes library is on your internal drive, this may happen
    The system was not shoot down correct, e.g. "pulled the plug"
    The iTunes library (database) got corrupted
    First Aid for internal hard drive
    Close iTunes
    Reboot system
    Go to Workplace -> right click external drive -> choose "clean up"
    After the tool shows "done" (could last some time depending on size of drive)
    Reboot system, restart iTunes
    If none of the above fixes your problem, post here.

  • The iTunes Library.itl is locked, on a locked disk, or you do not have write permission for this file.

    I just had to reset my entire laptop to factory settings, therefore my original iTunes was erased, leaving my iPhone 4 no accessibility for new music. I had to download CopyTrans so that I could transfer all things on my iPhone 4 onto my new iTunes. It said it transfered properly, but when I try and open iTunes,"The iTunes Library.itl is locked, on a locked disk, or you do not have write permission for this file." pops up. Please help.

  • SQL 2014 cluster installation on mounting point disks error: Updating permission setting for file

    Dear all,
    I am attempting to install SQL 2014 fail over cluster under a physical windows 2012 R2 server which have mounting point disks.
    At the finish of setup I get the following error message.
    Could you please help me on this?
    Thanks
    The following error has occurred:

The file permission setting were supposed to be set to 'D:P(A;OICI;FA;;;BA)(A;OICI;FA;;;SY)(A;OICI;FA;;;CO)(A;OICI;FA;;;S-1-5-80-3880718306-3832830129-1677859214-2598158968-1052248003)'.

    I am using an administrator account which have all security rights (cheched on secpol.msc mmc) needed for installation.

    Hi Marco_Ben_IT,
    Do not install SQL Server to the root directory of a mount point, setup fails when the root of a mounted volume is chosen for the data file directory, we must always specify
    a subdirectory for all files. This has to do with how permissions are granted. If you must put files in the root of the mount point you must manually manage the ACLs/permissions. We need to create a subfolder under the root of the mount point, and install
    there.

  • Changed Permission Settings: "System extension cannot be used"

    I was having some weird problems with file sharing on my network recently, so I tried changing around some of the permissions on my drives to see if I could resolve it. For some reason I was getting messages saying I didn't have permission to copy files from one computer to another on my network. This seemed to come on randomly as we have been doing file transfers this way for quite some time now. I looked at our file sharing preferences in the System Preference's and added all 4 drives from my Mac Pro in there and made sure that my username had full read and write capabilities. I then tried logging into my Mac Pro from my iMac, just like I've done in the past, and I was still unable to copy the files. So I removed all the folders and turned off file sharing. I then clicked 'Get Info' for my main Macintosh HD and tried changing the permission settings there. I clicked the option to make my username the owner, and then I clicked 'Apply to enclosed items...' and this brought up a progress bar that I let go for about 10 minutes. Then I got a pop-up error message stating "System extension cannot be used" and had an extension path listed underneath, saying it was installed improperly and cannot be used. This happens an endless amount of times. It seems to be giving me this message for every single extension on the computer. If I hold down enter the pop-ups just keep coming with different extensions listed.
    I hope someone with some insight on how permissions work in OS X Lion can give me some advice on how to resolve, and possible the correct way I should be setting up sharing if I've been doing wrong all this time. What strikes me as odd is that I never had any issues with sharing anything up until about a week or so ago, and I can't remember if there were any system updates that I installed that might have something to do with this.
    Any help is much appreciated, thanks!

    I had this problem recently in addition to my laptop getting stuck on the Apple logo and spinning icon. It took me a long to time to work through it so I thought I would share what I did to make it easier for others.
    The best thing to do when having permission problems is to do a 'disk permissions repair'. You can do this using the disk utility app found in your applications/utilities folder. This will attempt to rewrite all the permissions that were incorrectly set. When it is doing this it is common to get a message saying 'ACL...found and not expected...' do not go and delete these files. Its normal for this correction process to take more than 30 minutes, for me it took an hour.
    If this proccess doesnt work for you than you can also try a disk repair.
    If you can't boot using the normal disk you can also access this program through the recovery boot (holding Command-R of Option at startup), through the safe mode (holding Shift on start up) or through a recovery CD. You can also boot in a terminal type mode but this is a last ditch effort as a misspelt command could do more damage. personally, because I do not know what the commands I am using actually mean, I would recommend talking to a person at apple then using this approach.
    Hope this helps

  • Missing/corrupted system file in ..\system32\config and in ..\repair folder

    Hello everyone,
       Could you please help me with this proble ? I have got Windows XP PRO SP3 OEM.
    Today when I started pc i have got error meesage system file in Windows/system32/config missing. When I look into folder system file is here, but maybe he is broken. I said fine no problém I have got Windows/repair. I only need to copy default file to config
    folder.
    But..
    When I wanted to copy system file from Windows/repair folder there is no system file only system.bak. So I copy this file into Windows/system32/config and rename it onto system. I tried reboot PC, I saw starting Windows logo I almost jump into air, but after
    few seconds my smile disappear. I got automatic restart. I tried it again, again and again same. So I tried run pc in safe mode with same result.
    On the internet I read its can be by oem version of system. But where can I get system file now. Its possible to take system file form another pc ? Thank you for your advice. 

    Problem solved.
    There is solution which help me, so maybe it can help to others.
    Its better when you can unplug disk from pc and connect it to another via usb or via ata/sata such as another disk in the pc.
    1. At first at computer you need to see invisible files and protected files of operation system.
                          Computer > F10 > Tools > Folder options
    2. Now on the "corrupted disk" in the root you can see folder called "System volume infomation", but I think you dont have permission for it, right ?
                           Right click > Properties > Security > Add your self and add rights
    -now you can open system volume information folder
    3. open _restore{hexa} folder. Now zou can see a lot of folders started RP<number>, try to open the folder with higher nubmer. Next open snapshot folder. Now you can see a lot of files. But we want
    _REGISTRY_MACHINE_SOFTWARE or _REGISTRY_MACHINE_SYSTEM, choose what you need. Now copy file whant you need for example _REGISTRY_MACHINE_SYSTEM and rename it for SYSTEM.
    4. Open this path Windows\system32\config and rename your corrupted file. For example "system" to system.bad
    5. Last copy your new "system" file from SYSTEM VOLUME FOLDER which you created in step 3 to Windows\system32\config folder.
    6. Plug your hdd back into your pc and start pc and hope all will be fine :) .
    I hope this instruction will help someone, good day and smile :)

  • Malicious or not? Message popped up: Mozilla security found (something like too much, forget exact word) activity on your computer so it will do a fast scan of system file. With OK button.

    I was looking at youtube.com, which always tells me my browser is not supported and recommends I download Firefox, but that is what I was using, so I went to Firefox to check for updates. (I think I also had freecycle.org open.) Then this message popped up in a new page: Mozilla security found (something like "too much", forget exact word) activity on your computer so it will do a fast scan of system file. There was an OK button. The page address was: http://update17.stegner.ce.ms/index.php?Q7Lhl9ShbRxGJXpkM1VLSi4ZE8H4pTedoVPySgeppM3VpC+thEspcFG7qxHgn1pdsC2h5ygPGWI3t5hXqMzL9EQaZZ3J1e3CKXgCb0Qp. I did not click OK but copied the link and closed the window which closed the internet. I have never seen this before and would like to know if it is really Mozilla or possibly something malicious. Thank you.

    Good catch. That almost certainly is an invitation to download malware.
    There are a lot of infected web sites pushing "fake antivirus" software. If you have any doubts about whether your system might have become infected, you can supplement your regular security software with these two highly regarded scanners:

  • How can I repair Vista system files with only a Toshiba recovery disc??

    I have pretty much come to the conclusion that the reason I can't install Vista service pack 2 is due to some corrupt vista files. I ran the program that checks that system files and it said some are corrupt. There are some things I can't do, like turn on the Windows firewall even from that special adminostrar screen, or if I schedule a check disc scan, when I reschedule it for start up, it doesn't do it at startup. I had a Red Screen about a year ago, and it did a bunch of stuff and at the end, it said you had a major event and contact your administartor. Well, I am the administartor, lol. Anyway, it worked fine and I attribute these problems to that event.
    Vista discs come with a repair option. All I have is the Toshiba disc that lets you reinstall the Toshiba and Vendor applications OR reformat the hard drive. I am not going to spend days trying to get my system back to where it is by tracking down everything I have installed especially when its working. Is there a work around? I will buy a Vista Home Premium disc if I have to before refortmatting. I have an x205-S9349 with Vista Home Premium. THANKS!

  • Why is Itunes cluttering my music folder with system files?

    Ok i was using windows 7 before this and it was fine. Then i reformatted my drive and put windows 7 again. Downloaded latest itunes v9 and installed. Copied my entire music library backed up on my external hd and copied it to the music folder under the libraries section. In windows 7 the "my music" folder under user>documents and settings is actually the same as the "music" folder in the libraries on your pc. The music folder in libraries simply can compose of multiple folder so it simply displays all the contents of the "my music" folder and can also include other folders.
    Anyhow itunes screw up indexing my library but thats a whole problem of another sort. The main issue is that after it sees my music library and after I have downloaded something it does this. http://img169.imageshack.us/i/65030372.jpg/
    In that link as you can see in music under libraries it just leaves all those system and downloaded files.There actually ends up being hundreds after it gets album/song artwork since each artwork picture comes up as a ict2 file.
    However if i go to the my music folder in documents and settings it neatly tucks away all those files into their respective folder in itunes media or artworkd, despite the few core library files. http://img223.imageshack.us/img223/5956/55950795.jpg
    AT the moment i have deleted all the music in my library. Deleting those system files simply makes itunes no longer see an library. I have tried reinstalling with no avail. Why is it putting everything in folder in my music but not doing the same in music-libraries which is the same identical folder.

    This is just a thought, because I've not played with Windows 7, but near the top of your 1st image it says *Music Library, Includes 2 Locations*. I think you're looking at a view there which will display the contents of all possible music storage locations and the contents all of their subfolders, i.e. like a search result box. The other image corrsponds to a regular folder layout. iTunes stores an Album Artwork folder inside the main iTunes folder along with it's main database and a number of other supporting files. These files are required for iTunes to work so you can't just delete them. If you want to look at your media folders the use Windows Explorer to look inside *iTunes\iTunes Media*.
