Setting DNS Server di Ubuntu

When using the internet, then it implies that we use DNS (Domain Name System). The main function of this control system is to translate host names into IP numbers (IP address) or vice versa so that the name is easily remembered by Internet users. System control also serves to provide information about a host to the entire Internet network. About how the DNS Server itself will not be discussed in this article but the way its setting alone secaara simple.

1. Installing Bind

Software that is widely used as a DNS server is Bind. Of course we must first install this application.

# Sudo apt-get install bind9

Next install again the next package, namely dnsutils

# Sudo apt-get install dnsutils

2.The next step, ie edit the Ethernet card that will be used later.

# Nano / etc / network / interfaces

Select the Ethernet to be used for example eth0 with ip 192.168.44.2 DNS Servers it. The contents also his netmask and gateway.

3. Then edit the file / etc / bind / named.conf.options

# Nano / etc / bind / named.conf.options

Remove the "/ /" and enter DNS Server ip the same as before.

4.  Next, edit the file / etc / bind / named.conf.local

# Nano / etc / bind / named.conf.local

Here the DNS server is named bayuwicaksono.com. Correction on the setting of the second zone, which is on file "/ etc/bind/db.192"; not a file "/ etc/bind/db.44";.

5. The next step by adding the file / etc / bind / db.local into the directory / etc / bind / db.bayuwicaksono.com

# Cp / etc / bind / db.local / etc / bind / db.bayuwicaksono.com

Then edit the files you have added earlier

# Nano / etc / bind / db.bayuwicaksono.com


Here only name server is loaded and also the DNS server ip alone that could have also added to mailserver, ftp server or the other.

6.The next step is almost the same as the previous step by adding the file / etc/bind/db.127 into the directory / etc/bind/db.192

# Cp / etc/bind/db.127 / etc/bind/db.192

Then edit the files you have added earlier

# Nano / etc/bind/db.192

7. Then edit the file / etc / resolv.conf

# Nano / etc / resolv.conf

8. Then again edit the file / etc / hosts file to add the host computer information.

# Nano / etc / hosts

9. The final step to restart the services that have been in previous settings.

# / Etc/init.d/bind9 restart

# / Etc / init.d / networking restart

10. After all the settings then the live test DNS server is already running.

how to install Kubuntu KDE in Ubuntu

Ubuntu default desktop uses Gnome window manager, which can be a difficult transition for Windows users. KDE desktop will be much more familiar to Windows users, such as KDE has something comparable to the start menu.

If you've installed Ubuntu, and you do not want to completely reset with Kubuntu, you can only install the KDE window manager to install kubuntu-desktop package and its dependencies.

You can install kubuntu using GUI tools, but the easiest way is to open a terminal window, and type the following command:

sudo apt-get install kubuntu-desktop

You will be prompted for a password, and then you will be asked again to ask if you really want to install. Press Y to continue, and let the install begin.

Download all the updates can take a while, so you might want to get a cup of coffee or something. You will be prompted to choose the login manager, which you can select as gdm (ubuntu) or kdm (kde). I decided to leave the default gdm.

Reboot the computer, and when you get to the login prompt, click the Options button in the lower left corner:

You will be prompted to select the session you want. Here we will click KDE to continue.

Login, and you should now see the KDE desktop! All applications are found in a menu-like "Start", as you can see:

Note: If you are running Ubuntu inside VMware and end up with some display issues which is really weird screen resolution is really great, but the desktop shows at 800 × 600 instead (see screenshot), there is a fix for this.

When I encountered this problem, I also can not use a mouse. I rebooted, and logged back into Ubuntu desktop instead of KDE, and go into the directory / etc/X11 /.

You may notice that your xorg.conf file backed up during installation xorg.conf.1 / KDE Kubuntu. Just copy xorg.conf.1 back into xorg.conf, reboot, and everything should be fine.

Again, do not mess with the xorg.conf file unless you are really experiencing this problem.
