How to share folders in Linux using samba

Have you tried sharing a folder in Linux, especially in OpenSuse? If you open your File Browser/Nautilus and you right clicked on a folder, you will see a “Sharing Options” and when you try to share a folder and hit on the “Create Share” button, there’s an error prompting at the window: ‘net usershare’ returned error 255: net usershare: usershares are currently disabled.

Well the solution to this problem is quite simple:

Note: Before starting make sure that Samba is already installed and that the Samba daemon are already started:

Starting the Samba daemon

As root:

rawswift:~ # /etc/init.d/smb start
Starting Samba SMB daemon                                            done
rawswift:~ #

Now here’s what you will do next (as root):

  1. Edit ‘/etc/samba/smb.conf’.
    rawswift:~ # vi /etc/samba/smb.conf
    

    add the following under the “[global]” category:

    usershare allow guests = Yes
    usershare max shares = 100
    usershare owner only = False
    
  2. Create the ‘usershare’ directory (this is where Samba will store the lists of shared folders).
    rawswift:~ # mkdir /var/lib/samba/usershares
    rawswift:~ # chgrp users /var/lib/samba/usershares/
    rawswift:~ # chmod 1770 /var/lib/samba/usershares/
    
  3. Then finally, restart Samba daemon:
    rawswift:~ # /etc/init.d/smb restart
    Shutting down Samba SMB daemon                                       done
    Starting Samba SMB daemon                                            done
    rawswift:~ #
    

That’s it! Simple, eh?

Share a folder

  1. Open your file browser/Nautilus.
  2. Right click the folder you want to share.
  3. Click ‘Sharing Options’.
  4. Tick ‘Share this folder’ and ‘Guest access (for people without a user account)’.
  5. And hit ‘Create Share’ button.

Sun’s VirtualBox on OpenSUSE 11.1

Here’s how to install VirtualBox on OpenSUSE 11.1:

  1. First, you’ll have to download the package from Sun’s website.
  2. Get the right package for your OS platform (32-bit or 64-bit). I had the mistake of installing the wrong package. You can check your platform by running ‘uname’ command with ‘-a’ (print all information) argument:
    ryan@rawswift:~/Desktop> uname -a
    Linux rawswift 2.6.27.7-9-default #1 SMP 2008-12-04 18:10:04 +0100 x86_64 x86_64 x86_64 GNU/Linux
    ryan@rawswift:~/Desktop>

    A 64-bit kernel will give you ‘x86_64 x86_64 x86_64′ and a 32-bit would show ‘i686 i686 i386′.

  3. After you’ve download the package, it time to install it:
    ryan@rawswift:~/Desktop> sudo rpm -i VirtualBox-2.1.2_41885_openSUSE111-1.x86_64.rpm
    Creating group 'vboxusers'. VM users must be member of that group!
    ryan@rawswift:~/Desktop>

That’s it! Now run ‘Sun xVM VirtualBox’ on your application menu or ‘VirtualBox’ on your shell. Enjoy!

Problems and fixes (especially on a 32-bit and OSE package)

  • VirtualBox’s library requirements. Install the following:
    pam-devel
    libqt2-32bit
    libqt4-x11-32bit
    SDL-32bit
    libxslt-32bit
  • After running VirtualBox, it doesn’t show up on screen. Run VirtualBox on shell:
    ryan@rawswift:~/Desktop> VirtualBox
    WARNING: The vboxdrv kernel module is not loaded. Either there is no module
             available for the current kernel (2.6.27.7-9-default) or it failed to
             load. Please recompile the kernel module and install it by
    
               sudo /etc/init.d/vboxdrv setup
    
             You will not be able to start VMs until this problem is fixed.
    /usr/bin/VirtualBox: line 72: /usr/lib/virtualbox/VirtualBox: Permission denied
    /usr/bin/VirtualBox: line 72: exec: /usr/lib/virtualbox/VirtualBox: cannot execute: Success
    ryan@rawswift:~/Desktop>

    If the above error appears, you should run ‘vboxdrv’ script to create the VirtualBox kernel module:

    ryan@rawswift:~/Desktop> sudo /etc/init.d/vboxdrv setup
    Stopping VirtualBox kernel module                                    done
    Removing old VirtualBox netflt kernel module                         done
    Removing old VirtualBox kernel module                                done
    Recompiling VirtualBox kernel module                                 failed
      (Look at /var/log/vbox-install.log to find out what went wrong)
    ryan@rawswift:~/Desktop>

    If it fails to compile, install ‘kernel-source‘ through YaST. Then run ‘/etc/init.d/vboxdrv setup’ again.

    ryan@rawswift:~/Desktop> sudo /etc/init.d/vboxdrv setup
    Stopping VirtualBox kernel module                                    done
    Removing old VirtualBox netflt kernel module                         done
    Removing old VirtualBox kernel module                                done
    Recompiling VirtualBox kernel module                                 done
    Starting VirtualBox kernel module                                    done
    ryan@rawswift:~/Desktop>
  • Permission denied:
    ryan@rawswift:~/Desktop> VirtualBox
    /usr/bin/VirtualBox: line 72: /usr/lib/virtualbox/VirtualBox: Permission denied
    /usr/bin/VirtualBox: line 72: exec: /usr/lib/virtualbox/VirtualBox: cannot execute: Success
    ryan@rawswift:~/Desktop>

    Run ‘chmod’ on ‘VirtualBox’. This will set the execute bit:

    sudo chmod +x /usr/lib/virtualbox/VirtualBox
  • Driver mismatch. If an error box appear when you ‘Start’ a virtual machine:
    The VirtualBox support driver which is running is from a different version of VirtualBox.
    You can correct this by stopping all running instances of VirtualBox and reinstalling the software.
    (VERR_VM_DRIVER_VERSION_MISMATCH).
    
    Result Code:	NS_ERROR_FAILURE (0x80004005)
    Component:	Console
    Interface:	IConsole {e3c6d4a1-a935-47ca-b16d-f9e9c496e53e}

    Check your VirtualBox package platform (64-bit or 32-bit, see the tutorial above).

Brasero cannot detect drive: No available medium

I’ve experience a problem with Brasero. After a fresh intall of OpenSUSE 11.1, I tried to burn an ISO using Brasero, I had no problem with it on my previous install or so I think. When I try to burn, it couldn’t detect my DVD drive: “No available medium” but the DVD disc are properly placed inside the tray. Anyway I’ll be post here the quick fix I did to get it working:

Here’s it is:

  1. Open YaST
  2. Go to ‘Security and Users
  3. Click ‘User and Group Management
  4. Edit your profile
  5. Go to ‘Details‘ tab
  6. Then on the ‘Additional Groups‘, check the ‘cdrom
  7. Click ‘Ok‘ to save setting

Now open Brasero and start burning!

Note: If Brasero still can’t detect your DVD drive, restart your system this would fix it.

How to remove “Online Help” and “openSUSE” icon on OpenSUSE 11.1

After the installation, The first thing I do is to remove those icons because first, I don’t use it and second, I like my desktop clean.

Here’s how you can remove the “Online Help” and “openSUSE” icon on Gnome desktop:

As root, change directory to ‘/usr/share/dist/desktop-files/’ then delete or move this files:

  • GnomeOnlineHelp.desktop
  • SuSE.desktop

Remove

rawswift:/ # cd /usr/share/dist/desktop-files/
rawswift:/usr/share/dist/desktop-files # rm *

Move

rawswift:/ # cd /usr/share/dist/desktop-files/
rawswift:/usr/share/dist/desktop-files # mv * /to/backup/folder/.

After you remove or move it, notice that the two icons will automatically disappear on the desktop (must be a daemon, run by Nautilus Greeter Application, ‘ggreeter’).

I hope this helps!

Update!

I just found out about this! While I was removing applications on session startup, I’ve noticed an entry named ‘SUSE’ that run an application called ‘ggreeter’. I’m not really sure if removing it will disable those icons, anyway I continue on and disable that entry. The name just gave me a hint and so far I haven’t encountered any problem. Here’s how to disable it:

  1. Open the ‘Control Center
  2. Click ‘Sessions‘ under ‘System‘ category
  3. On ‘Startup Programs‘, uncheck ‘SUSE
  4. Then click ‘Close‘ button

What ‘SUSE’ does is run ‘ggreeter –once’ on startup, must be a daemon.

Freshly installed OpenSUSE 11.1

I’d upgraded my office workstation’s OS from OpenSUSE 10.3 to 11.1. Been waiting for a chance to install this new version, since it’s public release (December 2008).  I’ve been using OpenSUSE as my primary OS for web development at the office and run Windows XP in VirtualBox. After years of trying out different Linux distribution and BSDs. I’ve never seen anything quite like OpenSUSE. So! for years I’ve been stickin with it and I think I’ll never let go.

Still stuck with Windows? Go get OpenSUSE!
