Step 1: Connect your digital TV box to an aerial and power supply.

Connect your TV box to an aerial or digital supply. Also, make sure your device is connected to a power supply.

Step 2: Connect the HDMI to DVI cable

Connect your HDMI side of your HDMI to DVI cable to the digital TV box. Also, hook the DVI output side to the Dell TFT monitor. Make sure your TFT monitor is also connected to a power supply.

Step 3: Connect the audio output of the TV box to the input of a stereo or  a sub-woofer

The sound generated by your digital TV box needs to be amplified when you are watching TV. Hence, you need to connect it to a stereo system, amplifier or a sub-woofer.

Most digital TV boxes come with RCA cables coded with red and white colors. You need to connect that cable to your digital TV box and your stereo

Step 4: Power on everything and search for Channels

Once everything is said and done, power on your digital TV box, TFT monitor and amplifier/stereo system/sub-woofer.

Your TFT monitor will display the output from the digital TV box and because this is the first time you are setting up the system., you will be prompted to search for channels.

Once the searching is complete, you will see crisp images of your TV and you will be able to enjoy  a stereo sound from your TV box. Enjoy.

How to Disable Apache 2.4 Directory Browsing On Ubuntu 16.04

Apache is a corner stone of most web applications. The modern open source web server is critical in running your hosted websites and software. It supports most Operating systems including Windows and Linux so it should work pretty well with your Ubuntu 16.04 distribution.

However, since Apache is placed at the edge of your network, it can become potentially vulnerable.  Majority of web applications attacks occur due to information leakage.  Malicious attackers can utilize directory listing to gain a better insight of your web application’s directory and file structure.

For instance an attacker can run a URL like from any browser. If directory browsing is not disabled your Apache server will list all the files in that directory and this would speed up the hackers’ reconnaissance process.

One of the most practicable steps in securing your Apache web server is to disable directory browsing. This limits the Apache server from listing the directory files if there is no default index file (e.g. index.html) defined on that directory.


Step 1: Open the Apache Base Configuration File for Editing Using nano Text Editor

If you are running a single site, editing the Apache base configuration file might a good option. This will eliminate the need of creating separate configuration files and symbolic links which can be time consuming for a single website.

To edit the base Apache configuration file using nano, type the command below.

sudo nano /etc/apache2/apache2.conf
  • Once the nano text editor opens, find the directory option directives and you will see some text similar to the below excerpt.
<Directory /var/www/>

            Options Indexes FollowSymLinks

            AllowOverride None

            Require all granted


In Apache, options pertaining to a particular directory are enclosed in a paired <Directory> and </Directory> tags inside a configuration file.

  • The Options None directive tells Apache that there are no specific features applied to that directory.
  • AllowOverride None specifies that the directory options will not be overridden by any .htaccess file.
  • The option Followsymlinks simply tells the Apache web server to follow symbolic links in that directory. This is very useful for shared applications such as PhpMyadmin which must be shared across different websites.
  • The Indexes option instructs Apache to prepare and display a list of pre-formatted index in case the directory does not contain a default index file such as index.html or index.php.
  • The allow from alldirective authorizes any host to access documents and services within that directory.

We are interested in the Indexes options and we are going to change it to disable directory listing

Step 2: Changing the Indexes Directive

We need to change Options Indexes FollowSymLinks to Options -Indexes +FollowSymLinks on the nano text editor that we opened above. Please note, adding a preceding “-” sign on an option disables and adding a “+” sign enables a directive as shown below.

<Directory /var/www/>

            Options -Indexes +FollowSymLinks

            AllowOverride All

            Require all granted


Once you have finished editing the file, press CTRL+X, Y and then Enter to save the changes

Step 3: Disabling Directory Browsing on Virtual Hosts Files

Apache’s lion market-share is attributed to its capability of running unlimited virtual hosts in a single instance. This allows website owners to run numerous sites, sub-domains and application on a single instance.

Some websites do not consume a lot of server resources and the best way to get the most from your Vultr VPS is to utilize this Apache virtual hosting feature.

While the virtual host is a bullet-proof for hosting multiple sites, its configuration can become a double-edged sword.

Managing the configuration files for virtual hosts can be difficult. However, there is a better approach. Each virtual website configuration file can be placed under the /etc/apache2/sites-available/ and a symbolic link would be maintained under /etc/apache2/sites-available directory.

Apache will then maintain and load the configurations for each website independently. 

With that in mind, if you are hosting multiple sites, you may disable directory browsing directly on each virtual host configuration file. By default, Apache comes with a single default virtual host.

Type the command below to edit the configuration file:

sudo nano /etc/apache2/sites-available/000-default.conf

Add the details below before the </virtual host> closing tag at the end of the file to disable directory browsing.

<Directory /var/www/html >

Options -Indexes +FollowSymLinks -MultiViews

AllowOverride All     
Require all granted


The Order allow,deny directive makes deny directives to take precedence as they are applied after the allow directives.

Remember to press CTRL+X then Y and Enter, when you finish editing the /etc/apache2/sites-available/000-default.conf file for the changes to take effect.

You may follow the same procedure above for any virtual websites that you have on your Ubuntu 16.04 server. Remember all virtual hosts configuration files end with a .config extension. For example, to edit the configuration file for an virtual host, enter the command below.

sudo nano /etc/apache2/sites-available/

Then, add the following details at the end of the file just before the </virtual host> closing tag.

<Directory /var/www/ >

Options -Indexes +FollowSymLinks -MultiViews

AllowOverride All     
Require all granted


Important: Remember to match your virtual host directory to your website’s public folder. In the above example, our website files are found under /var/www/

Step 4: Restarting Apache Web Server

Finally, we need to restart Apache for the changes to take effect by typing the command below:

sudo service apache2 restart


That’s all when it comes to disabling directory browsing. Remember to double check whether the changes have been effected by typing your domain/IP address on your browser followed by a forward slash and the folder you want to check.

For example, to double check a config folder under your website, we should type. http://www.example.conm/config.

If the directory browsing was successfully disabled, we should be greeted with a forbidden error message, “Forbidden you don’t have permission to access /config on this server. Enjoy your Apache web server!
