Installing Oracle VM Extensions under Ubuntu

To install the Oracle VM Extensions that will allow you the usage of USB under Virtualbox do the following:


  1. Download and install the same version of the extensions as the Virtual box.
  2. Type Sudo usermod -aG vboxusers yourUserName in a terminal.
  3. Log off and log in again.
  4. Open the VM control panel and tick under USB to use USB 2.0.
  5. Plug the USB device. The OS will grab the device. Eject it and the Virtual box will see it is now free and capture it for itself.
I have tried that with various USB devices; some where found straight away (like an iPod for example), others never did. It's a hit a miss I guess.

Remove the background in desktop shortcuts in Xubuntu

To remove the background color on your Xubuntu desktop do the following:

Open your editor of choice with the sudo command.
E.g. sudo gedit ~/.gtkrc-2.0

Paste the following lines into the empty file:
style "xfdesktop-icon-view" {
XfdesktopIconView::label-alpha = 0
fg[NORMAL] = "#ffffff"
fg[SELECTED] = "#000000" }
widget_class "*XfdesktopIconView*" style "xfdesktop-icon-view"


Save the file and log off/log in to see the changes. Now your desktop labels will have a white foreground with transparent background.

You can change the #ffffff (white) to any color it suits your desktop colors. Don't forget to change the #000000 (black) to something that will be visible on your wallpaper.

Add a second HDD to ClearOS

Connect to the console on ClearOS.
  1. Type fdisk -l to display the list of HDD in your system.
  2. Type fdisk /dev/hdb to create a partition on your second drive (in this case hdb). Select P for primary partition, 1 for Partition number and Hex Code 83 (for Linux file system). At the end type W to write the partition.
  3. Type mkfs.ext3 -b 4096 /dev/hdb1 to create a filesystem to that partition. Follow prompts.
  4. Type sudo mkdir /mnt/DataDrive to create a mounting point call DataDrive (or any other label you see fit).
  5. Type mount /dev/sdb1 /mnt/DataDrive to mount the DataDrive.
  6. Type nano /etc/clearos/flexshare.conf to edit the configuration file that controls the flexshares.
  7. Find the line that shows FlexshareDirCustom and change it to FlexshareDirCustom==Disk1:/mnt/DataDrive/ to make permanent the change. Press Control+X to exit nano. It will ask you if you want to save. Say Yes.
Now you can use the second hard drive in ClearOs. I would like to thank all the people with their posts that helped me to be able to add a second HDD (finally) to my ClearOS system.

To purge the installer from the system

sudo add-apt-repository ppa:webupd8team/java
To re-enter the repository into the list

sudo apt-get update
To update the list

sudo apt-get install oracle-java7-installer
To download and install the package

And that was it.

WSUS doesn't report client status

Some times WSUS server will not report the status of client computers into the management screen. If the reset authorisation and reportnow commands don't work try the following:


  • Open a command prompt
  • Type in:
  1. net stop wuauserv
  2. REG DELETE "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate" /v SusClientId /f
  3. net start wuauserv
  4. wuauclt /resetauthorization /detectnow
  5. wuauclt /reportnow 
And that's it. Clients should start reporting back after a refresh in the WSUS.

Fix slow connection to windows shares in Ubuntu 12.04

I had this annoying issue with my Ubuntu 12.04; it wouldn't connect sometimes to a NAS system in my network. Sometimes it would, other times it would say can't connect to share. I was pulling my hair (what ever is left after all those years in IT support) when finally I found a mention to the same problem online. Now there were a few suggestions that unfortunately didn't work for me. At the end I did a bit of mix and match and I got a solution:

open a terminal window and type the following:
sudo apt-get install smbfs winbind


Next type in:
sudo gedit /etc/nsswitch.conf
to open the nsswitch file for editing

There is a line showing the following:
hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4

change it by adding the word 'wins' before the 'dns' like so:
hosts: files mdns4_minimal [NOTFOUND=return] wins dns mdns4


One quick reset later, and my Ubuntu would connect to the share straight away!

I would like to thank all the people that contributed to this solution. Unfortunately I can't remember all the web sites I got ideas from, so a big THANK YOU to each and all of you.

Windows firewall is missing in Services


That is mainly due to a virus/malware infection. To repair the registry entries do the following:

*** Taken from http://www.hageltech.com/blog/2012/02/07/base-filtering-engine-problems.html ***

First of all apply the firewall registry fix: 
http://dl.hageltech.com/blog/Firewall-Repair-Windows-7.reg

Then apply the BFE reg fix 
http://dl.hageltech.com/blog/BFE-Repair-Windows-7.reg

Fix permissions in the registry:

1.     Open Registry Editor (type regedit in Start Menu):
2.     Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE\Parameters\Policy
3.     Right-click and select Permissions
4.     Click Add, enter “Everyone” and click OK
5.     Click on Everyone in the list at the top, and check the “Allow Full Control” checkbox below.
6.     Click OK to dismiss this dialog.

**********************************************************

Copy and paste the following to a .bat file and run it as Administrator.

sc config MpsSvc start= auto
sc config KeyIso start= auto
sc config BFE start= auto
sc config FwcAgent start= auto
net stop MpsSvc
net start MpsSvc
net stop KeyIso
net start KeyIso
net start Wlansvc
net start dot3svc
net start EapHostnet
net stop BFE
net start BFE
net start PolicyAgent
net start MpsSvc
net start IKEEXT
net start DcaSvcnet
net stop FwcAgent
net start FwcAgent

If you get an Error 5 for MpsSvc do the following:

Fix permissions on the SharedAccess registry

1.     Open Registry Editor (type regedit in Start Menu):
2.     Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SharedAccess
