  • Delete tunnel "sit0" failed: Operation not permitted

    I tried to connect to Ipv6 through a 6to4 tunnel, but I couldn't and now I cannot delete the tunnel and I cannot connect to internet at all because all traffic is being redirected to the unusable tunnel.
    When I created the tunnel I ran the following code:
    # ip tunnel add 6to4 mode sit remote any local 192.168.43.68 (which was my address)
    I tried to flush and delete the tunnel and it deleted "6to4", but " sit0" remains. When I try to delete it, it says
    # ip tunnel del sit0
    delete tunnel "sit0" failed: Operation not permitted
    I did this as root, of course, and I need to delete it to get my Internet working again. Help please!
    Oh, and rebooting or modprobe -r sit has not resolved the problem because the interface remains and it doesn't show any webpage, although I can see that it shows connected.
    Is there any config file where tunnel configuration is saved so I could modify the file manually and reboot without it being active again?

    I'm sorry. I actually had a DNS problem that I hadn't figured out. I still have not deleted the sit0 interface, but it's not giving me problems (it wasn't exactly the cause).

    Is there anything to look out for here? What have I done wrong? Did I reformat my drive incorrectly? I chose Mac OS Extended (Journaled).
    Tried also to fix permissions from the install disk but got the same errors.
    Any help would be appreciated. Thanks

    Hmm I haven't seen so many errors either.
    the number of errors is not high at all. Leopard would very often produce at least 3 to 4 times as many.
    It could have something to do with me running snow leopard on a Macbook Pro 2.16 core duo and not a core 2 duo... ?
    no, that would not have anything to do with it. as i said, those are most likely just errors in the permissions database. as i said, leopard was notorious for those. snow leopard is not as bad but produces a number of them too. I just haven't seen this particular kind of messages before. reinstalling SL will fix them but it seems like a serious overkill in this case.

  • Mac OS X 10.6.8, receiving error message "Failed to check for updates. The operation couldn't be completed. Operation not permitted." How to fix?

    When I try to update my software, I'm receiving the error message "Failed to check for updates. The operation couldn't be completed. Operation not permitted."
    I'm using Safari 4.0.3. Yes, I know this is an old version of Safari - I can't update it, or any other software on my MacBook. Should I just wait for the Lion OS, or is there any kind of fix a non-technical Mac user like me can attempt without screwing up her laptop?
    I've tried clearing my cache and resetting Safari already - doesn't help. I've also tried to update after disabling my (Norton) antivirus software, thinking that might be interfering. None of these help.
    I don't know if it's a related problem, but also I can't download .pdf files from the internet, although I used to be able to.

    You should use the NortonAV uninstaller to uninstall it. Disabling the dreadful thing in the past hasn't always been sufficient for it to cease creating system havoc. The Mac NortonAV version has a long and well-earned reputation for doing truly seriously nasty things to OS X. Shame on Comcast for inflicting NortonAV on its Mac customers. It's not a matter of if NortonAV will mess up OS X but when and how badly. I can't help but wondering if some setting in your Norton AV has decided that NortonAV, rather than you, will be making executive decisions about what you are allowed to install on your computer and is keeping that fact a secret.
    After you are done uninstalling Norton use the finder to search for any Norton files that the uninstaller might have missed. Add the option to search for invisible files.
    After you have removed all the Norton bits and pieces restart in safe mode by holding down the shift key right after the startup chime. Keep holding down the shift key until you see the Apple logo and spinning gear. Safe mode does some maintenance tasks which means a much longer than normal startup time. Use Disk Utility to repair permission
    If your Mac works normally in safe mode restart. If things still aren't fixed you might want to give another shot at reinstalling Snow Leopard from the install DVD and applying the Mac OS X 10.6.8 Update Combo before taking your Mac to the Apple Store.
    If you feel the need to run AV software on your Mac use ClamXav in manual mode. It's donationware and doesn't seem to cause the litany of weird problems that are associated with other AV software.

  • Changed Ulimits values for the Oracle user and getting error -bash: ulimit: max user processes: cannot modify limit: Operation not permitted when logging in.

  • -bash: ulimit: open files: cannot modify limit: Operation not permitted

    Hi all,
    i´m preparing a linux 64bits environment to install Oracle 10g R2. I´m following the installation manual and there say that:
    Depending on the oracle user's default shell, make the following changes to the default shell startup file:
    For the Bourne, Bash, or Korn shell, add the following lines in the /etc/profile file (or the /etc/profile.local file on SUSE systems):
    if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
    else
    ulimit -u 16384 -n 65536
    fi
    fi
    Ok, I did it, so when execute the follow comand I get a error like this.
    tetis:/etc # su - oracle
    -bash: ulimit: open files: cannot modify limit: Operation not permitted
    oracle@tetis:~>
    Can anybody help me ?
    Regards,

    The limits for -u and -n are defined in limits.conf, it looks like the -n section is not working (-u is already 16384), just to double check, show us the output for:

  • HT4968 Calendar is locked on my Mac. I keep getting the message "The server responded with an error: Access to iCloud is not permitted. The server responded 403 to operation caldavmigrate to server queue able operation." How do I resolve?

    Calendar is locked on my MAC.
    I keep getting the message" The server responded with an error: Access to icloud is not permitted. The server responded 403 to oepration caldavmigrate to server queueable operation."
    How do I recify?

    We previously had a similar issue when migrating multiple accounts from MobileMe to iCloud.  The issue was resolved by disabling and then enabling iCal sync through iCloud on our iMacs in System Preferences.
    Always backup your calendar before troubleshooting (File > Export > iCal Archive).
    The following steps are roughly from a Apple Support Community discussion.
    Open iCloud in System Preferences.
    Switch off (uncheck) iCal sync in iCloud System Preferences pane.
    Backup iCal before doing this. You will need to remove calendar data.
    Open iCal and verify the iCloud account is removed in the iCal preferences under accounts.
    Close iCal, reopen System Preference and switch on (check) iCal sync in iCloud System Preferences pane.
    Reopen iCal and verify the iCloud account is enabled in the iCal preferences under accounts.
    At this point if the problem persists you might try completely signing out of iCloud and then signing back in. But remember to backup all related data (iCal, Contacts, Mail, Photostream, etc) before turning off iCloud sync!

  • Error mounting NFS share - mount.nfs: Operation not permitted

    I've got an NFS share on a FreeBSD server which I mount via fstab.
    It mounts automatically at boot and everything is fine.
    However, if I unmount it and try to mount it again I get:
    mount.nfs: Operation not permitted
    I have tried vers=3 and nfsvers=3 in fstab, but to no avail.
    rpcbind is allowed in /etc/hosts.allow.
    Does anyone have any ideas?
    fstab entry:
    server:/path/to/files /mnt/files nfs ro,hard,intr,nfsvers=3 0 0

    Tagging along, I have the same problem, although I have a different setup:
    - Server = Arch linux
    - Client1 = Debian Testing linux
    - Client2 = Arch linux
    On client1, I'm unable to mount all NFS-shares. 2 out of 3 mount ok and the third fails with this error (both through fstab and manually):
    # mount -a
    mount.nfs4: access denied by server while mounting (null)
    On Client2 I'm able to connect automatically and manually to all shares.
    Maybe it is Debian-related, but the debian user forums have not been of much help...
    THX for any input!

  • FB50L error: Postings to G/L accounts with open item management are not permitted

    Dear All
    I need your help.
    I am trying to do some adjustment to GR/IR clearing account in Non-leading ledger. Since for this account open item management is ticked, I am getting an error message 'Postings to G/L accounts with open item management are not permitted'.
    Now I have checked the forum to find some solution...but does not fit my requirement.
    I cannot create a new account. I cannot change the existing account. I tried OBA5, but the message persists.
    I also checked the notes.
    Appreciate a response on how the post to open item managed accounts in non-leading ledger.
    Regards
    Kunaal

    Hi Kunaal
    Usually, OIM accounts are not allowed for Non Leading Ledger postings... With EhP4 or 5, i guess, a new feature is added in GL Master whereby you can specify that a GL will be OIM for Leading Ledger and Not OIM for a Non Leading Ledger

  • Operation not permitted - Permission errors when restoring

    Hi Guys,
    I'm trying to restore some files from a time machine backup from a DIFFERENT machine (i.e. browse other Time Machines) to a different laptop.
    BOth machines run 10.6. When using Time Machine it didn't want to know about it with the graphical restore.
    I tried the browsing via Finder and drag/drop onto the new machine's desktop and no joy - error messages.
    Finally, I used the command line and the even used sudo, but got this error:
    mv: Linwood College//10Bi SS/Global Terrorism/Rainbow warrior comic.comicdoc: Operation not permitted
    The command I used was:
    MacBook:Grad School sam$ sudo mv -f Linwood\ College/ ~/Desktop/
    I did enter my password too, which is an Admin account on the machine.
    Any suggestions on how I can recover these files? I'd really like to get them off the external hard drive before I give up and wipe it.
    Appreciate all help in advance.

    What does that mean? Did you get an error message? If so, what? If not, what happened?
    You should be able to restore to an "alternate location," per #16 in the Frequently Asked Questions *User Tip,* also at the top of this forum.

  • Creating files in user directory results in "Operation not permitted" error

    Hello everyone,

    PowerMac G5 & PowerBook G4   Mac OS X (10.4.6)  

    That is good to know, but it will probably make it ever harder to locate the cause of this problem. In the meantime, I made a backup of my FileVault-enabled user directory on my PowerMac and reinstalled the operating system on my PowerBook. During the backup, I have encountered a couple of I/O errors so I'm guessing either the filesystem was damaged (and could not be completely repaired by Disk Utility, which I have tried) or the hard drive is damaged.
    Just to be on the safe side, I have ordered a new hard drive and exchanged it (wouldn't want to risk data loss with the old hard drive) and everything works perfectly again with a completely new user directory.
    I am still wondering what caused all this trouble though, since I want to avoid another incident like this in the future.
