Windows Server 2012 (R2) – Turn GUI off or on

Windows Server 2012 (R2) can be migrated with a single reboot to a Server Core and back. This quite handy feature is mostly used on domain controllers or Hyper-V controllers, this way you can install and configure your server roles with an GUI interface and afterwards go back to the Core edition to require lower recourses and have a small attack surface. These commands only work if you have installed the server with the GUI, you can’t install the GUI if you have installed the core edition.

If you want more information about the Windows Server Core features: please visit this link 

You can turn off the GUI with the following PowerShell command:

Or turn the GUI back on if you want to modify something on your server with the following PowerShell command:

Don’t forget to reboot after running these commands succesfully.

This can be done with the following command:


Acronis 11.5 Linux agent installation – Debian / Ubuntu

From my point of view is Acronis one of the best back-up tools on the market. They provide agent for different kind of OS’s, cloud storage support, central management and etc. Nevertheless installation of the Acronis 11.5 Linux agent has some dependencies that are not written out in the Acronis manual. Therefor I’m writing still how-to for the installation on Debian / Ubuntu.

This how-to is tested on Debian 6 & 7 and Ubuntu 12.04 (all i386), the installation of the Acronis Management server is not covered by this how-to. For detailed information on how to install and configure the Acronis Management server I need to redirect you to the Acronis 11.5 manual

First we need to download the up to date and correct Acronis 11.5 Linux agent, the best place for this is Acronis website @

So head on over to your account, go to “My Product & Downloads”, choose your product and download the agent on the Linux component tab. Once you have downloaded the Agent you will have a file called “ABR11.5AL_en-EU.i686”, this file needs to be transferred to your Linux server. If you are looking for a secure way to transfer file on and off your Linux server please check out WinSCP.

Once the Acronis 11.5 Linux agent is transferred to a temporary folder like /tmp , you will need to execute the following commands as root (su or sudo)

Give the appropriate rights

Update, upgrade, download and install the dependencies

Once all the dependencies are installed you can start the agent by executing

The installation process of the Acronis 11.5 Linux agent will start, now just follow the wizard and fill out the license and management server and your Linux Acronis Agent is configured and installed.

Installation Zabbix agent on Debian 7 x64

I could not find a tutorial that showed how to install the precompiled Zabbix 2.0 agents on a 64 bit Debian box, so I’m making a how to for Zabbix agent on Debian 7 x64 . This tut also works on Debian 6 x64 or x86.

The latest downloads for precompiled agents and source code for building servers is here. , there is no Zabbix agent on Debian 7 x64 so you will need the source code.

On the Debian system that is getting the agent (remember this is for 64 bit version of Debian, go to the Zabbix download site for the link to the 32 bit agent if your system is 32 bit):

You should be logged in to a root sudo or su session for the following

Change “Server=” option to the IP address of your Zabbix server, for example:

Exit and save the file

Change “LogFile=/tmp/zabbix_agentd.log” to:

Change “Server=” option to the IP address of your Zabbix server, for example:

Change “ServerActive=” option to the IP address of your Zabbix server, for example:

Change the hostname to the fqdn of the server or rem out the “Hostname=Zabbix server” line:

Exit and save the file

Exit and save the file

Now the Zabbix agent on Debian 7 x64 is installed. Go to your Zabbix server’s web interface and add the new system to hosts as you normally would and configure accordingly and you are done.


Antivirus Exclusions Microsoft Products

Running a good, constantly updated Anti-Virus program on your computers – server and workstations – is a must when looking into the potential risks in today’s IT world. However, when installing Anti-Virus software on a computer, you also risk having issues with some of the services and applications that run on these computers, most specially with the server machines. Anti-Virus software scans and sometimes locks files on the computers, and when you scan these files, performance and operating system reliability problems may occur because of file locking.

This is why it is extremely important to properly configure the Anti-Virus software to exclude specific files, file type and/or folders on the computers (most importantly – server machines) with an antivirus exclusions for Microsoft Products.
