Setup Oracle Virtualbox Network

So in this post, I will record how do I create a environment with networking. Let get to know the available network setting type that available in Oracle Virtualbox.

Available network type that can found in Oracle Virtualbox

• Not Attached 
• NAT (Default)
• Bridged Network 
• Internal-Network
• Host-only Network

Not Attached

It simple as there is no network connected. It is isolated from physical network and VM network. So the guest OS is stand alone without any connection and communication can make.

NAT

By default, the VM will set the network type to NAT.It work like the physical computer that behind the router. In the virtual case, the guest OS will sit behind the VM router. This connection can consider is the most secure way to access the network.

Bridged Network

Bridged networking connects a virtual machine to a network using the host computer's Ethernet adapter. This is often the easiest way to give your virtual machine access to that network. If you use bridged networking, your virtual machine needs to have its own identity on the network. In another word, your host computer (the Mac) will share its network connection with the virtual machines, they'll be sitting as if they were another computer on your network, everyone on the network will see them and be able to interact with them.

Internal-Network

Internal network which is the connection between guest OS. So the communication is only able to make between guest OS that in this mode. The guest OS is unable to communicate with the host. These network is isolated from the physical network.

Host-Only Network

With this network setting, it provide the connection between the guest and host computer. So other host, guest is unable to see the particular guest OS in the network. Another explanation with example is peer to peer connection between two computer in a LAN.

Install Android Studio

Recently the official Android Development website have release the new version of Android SDK know as Android Studio. So i get to try this new SDK and I found that there is very less guide on this. So now I here to share my installation of  the new Android Studio.

So make sure you have install the JDK and JRE with the version of 7.

Here the link to get JDK 7  and here to get JRE 7. Remember to accept the term & condition before proceed with download.

After you download install JRE and JDK. At the mean while you need to download the Android Studio as well. You may get the SDK from here.

The Android Studio is Ziped and install it. After install it, open it according your window platform bit. In my case, 64 bit Window 7 is locate at C:\Program Files\Android\Android Studio\bin\studio64.exe

If 32-bit is so double-click the Studio.exe

Reset Window Server 2008 Local Admin Password

After a long run of Window server 2008 without any documentation. When the Window facing issues and need the local admin account to perform some task or installation. So is ok if you forget your administrator password. So here I going to document the way to change the administrator password of Window server 2008.

Tools that require are:

Physically access to window server 2008, a window server 2008 installation disk for sure a CD ROM

Let begin.

Insert the Window Server 2008 CD into CD ROM then restart and boot into the CD. This process similar to install a new Window Server to a new machine, but take note you are going to change the password. So there is one of screen please chose Repair your computer at the left bottom of the window screen.

Then you need to chose command prompt to give the command to move and copy a file.

So first thing going to do is rename and backup the utilman.exe file. Below is the command.

MOVE C:\Windows\System32\Utilman.exe C:\Windows\System32\Utilman.exe.bak

Your screen will like screenshot below.

Next, we going to copy again the utilman.exe file. Below is the command.

COPY C:\Windows\System32\cmd.exe C:\Windows\System32\Utilman.exe

Your screen will similar to screenshot below.

Nearly done
After assign this 2 command, eject your CD ROM disk and reboot your Window Server. After reboot, at the Window login screen left bottom you will see a icon
. Click on the ease of access icon and run the command prompt.


Once you see the command prompt, give the command below.

net user administrator *

When you press enter it will ask you to enter new password and confirm the new password. Your screen will be like screenshot below.

Once you successful login the Window Server, please do not forget to delete the Utilman.exe and then rename Utilman.exe.bak back to plain old Utilman.exe.

My Begin of Software Development

I get to know how to begin the software development in my uni life. As those time quite a hard time for me to figure out how a software being created. Now i try to do some summary of my experience. I have the some experience in ASP .Net, Java, PHP.

Basically to begin an development for sure is an idea to start with. What application you going to develop / build. I wont mention the software development life cycle in here that was too bored start with those theory. For sure you need a tools to start a software development which is... tata.... a pc... lolx..

For the software tools that use to develop a application know as software development kit (SDK) or IDE. (Google it to know more about the different)

So for Java application development, I am begin by using BlueJ then follow by Netbeans. Both of this tools is very easy to setup like ABC. To setup of these tool you must have to install the java JDK before install this software. What i like this tool is it is FREE, this is one of the good thing about Java.

For the ASP development tool is MS Visual Studio. The language use might be C#, VB.... You may develop webpage, console application, desktop apps, and mobile app by using only this application. But this is license software. Installer size is huge and take time to install.

Lastly the most frequent use program to open those source code is Notepad++. I like this program very much as it able to open many file type of code file and formatted accordingly and colored to identify the reserve words.
