Thread: Network file sharing not working suddenly

  1. #1

    Default Network file sharing not working suddenly

    SUSE 13.1, 3.11.6-4 x86_64, KDE 4.11
    The latest thing I've discovered that has been broken by the latest series of updates is CIFS file sharing. I'm connected to a NAS device on the local network, and suddenly found myself unable to transfer files to and from the device. I can, however, view and browse the files over the network, just not open or transfer them.
    Furthermore, I can not connect to localhost via the network: If I try to browse \\127.0.0.1, I get a message stating "could not connect to host for smb://127.0.0.1/" That's never happened before.
    Here's the output of " systemctl status smb.service "
    Code:
     systemctl status smb.service

    I just checked, there is no "/run/samba" or "/var/run/samba" on this machine.
    How can I get my network file sharing services back online?

    I've got a work-around by stopping apparmor:
    Code:
    sudo rcapparmor stop
    But this leaves me patiently awaiting the bugfix.


    Furthermore, after stopping apparmor, I'm getting persistent tracker-miner processor spikes, and I still can transfer files to and from the NAS. My processor is currently at 90 degrees C, and shows no sign of slowing down.

    Just run "sudo /usr/sbin/logprof" to update the Apparmor profile and allow smbd and nmbd to create that directory.
    Then it should work fine with Apparmor again.

    You need Apparmor to prevent tracker from slowing down your system?
    That's an interesting approach...

    Why don't you just uninstall tracker then?

    I've had to do that twice; once, and then again after a reboot. The second time didn't seem to change as many things, so we'll have to wait and see if this is a fix, or a workaround I'll have to invoke every time I reboot.

    If I'm not mistaken, isn't that what Apparmor is supposed to do?
    # whatis apparmor
    apparmor (7) - kernel enhancement to confine programs to a limited set of resources.
    Anyway, tracker-miner-fs has , in my experience, been known to go a little inexplicably nuts every now and then, but not often enough to warrant complete removal, seeing as how the indexing enhancement it provides probably outweighs the occasional trouble it provides.

    You should have to do that only _once_!
    But logprof will of course ask you about any other things that have been blocked as well. So of course there can be new things every time you run it.
    But you should not just enable all of them, that would undermine Apparmor's presence, you could just as well uninstall it then.

    Only allow the stuff for smbd and nmbd (/var/run/samba and maybe /var/cache/samba should be enough, and of course the configured shares) and it should work without running logprof again.

    If I'm not mistaken, isn't that what Apparmor is supposed to do?
    Well, actually its purpose is to increase security by not allowing selected applications to access all things they want.

    But in tracker's case it would be better to just configure it to not index the stuff you don't want to index. I don't know how this is done though, I guess with "tracker-preferences". I never used tracker, this is one of the first things I uninstall, as I use KDE which has its own file indexer. No sense in running both...

    But I wasn't even aware that there was a profile for tracker included. Did you create one yourself?
    And it sounded to me like you completely block tracker with Apparmor. In that case it really would have been better to just uninstall it...

    Ah, if you're referring to Nepomuk, I just assumed tracker-miner worked with it. If Nepomuk works completely independently of tracker-miner, then I suppose I could afford to get rid of it.

    You probably know way more about it than I do. I have no idea how to configure tracker-miner, never tried, and probably never will, as I just uninstalled it.

    That's correct. Nepomuk and tracker (including tracker-miner) are separate things and work completely independent of each other.

    If you want to search in an application that uses tracker (GNOME applications mainly, nautilus f.e.), you have to run tracker of course.
    KDE applications like dolphin should use Nepomuk.

    Well, not really. The last time I searched for a way to turn off tracker I didn't even find any, that's why I always uninstall it...
    Btw, you can configure Nepomuk (and its file indexer) in "Configure Desktop"->"Desktop Search". But I guess you knew that already.
