DNS Slave Configuration

The benefit of DNS Master is that one no longer needs to memorize the ip address to access a domain. The DNS Master will translate or translate ip addresses into a domain name and vice versa because DNS master is the one who holds the complete list of a domain it manages. While the benefits of DNS Slave is a backup of DNS Master.

The DNS Slave is a backup DNS if our primary DNS occurs damage. There will be mutual transfer of information between the primary DNS and the DNS slave. The steps to build a Slave DNS are as follows:

Set up a new DNS server, the old DNS server keeps running. For configuring the DNS Slave, we must first install DNS with the same steps as in DNS Server. We have to install bind9 first and then do the Slave DNS configuration.

Edit and add configuration for forward and reverse on named.conf.local file.

Finally, restart the daemon from bind9.

The dns master should be rebooted after the dns slave finishes in settings.

Computer Graphics Project "MINION" Source Code with Glut OpenGL

Image
Hello !!! This time I post about computer graphics again. And yes, I will share a project which mainly used rotation and a little bit morphing. You can download this project here ( Download here to download glut and follow the instruction ) .The character used in this project is well known. Well here’s the depiction of this project. Minion !!! The eyes will rotate. And it’s smile will move up and down which give you a creepy smile hahaha.  So here’s the source code for this project : #include <stdio.h> #include <math.h> #include <GL/glut.h> #ifndef M_PI #define M_PI 3.141592653589793 #endif typedef struct { float x; float y; } point2D_t; typedef struct { float r; float g; float b; } color_t; ////////////// OpenGL drawShape Functions ver 1 ///////////////// void setColor(float red,float green,float blue) { glColor3f(red, green, blue); } void setColor(color_t col) { glColor3f(col.r, col.g, col.b); } void drawDot(float x,float y) { ...

Computer Graphics Project "Planet Orbit" Source Code with Glut OpenGL

Image
Hello there !!!  This time I will post a project in the past. It is about rotation and applied to make earth orbital with moon and sun. As reminder, for you who haven’t install glut you can download it in here and follow the instruction I uploaded too. You can download this orbital project in here too. The image above is the result of orbital project. Here is the source code for this project. #include <windows.h> #include <stdlib.h> #include <GL/glut.h> #include <math.h> void myinit() { glClearColor(0.0, 0.0, 0.0, 1.0); glColor3f(1.0, 0.0, 0.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-400.0, 400.0, -400.0, 400.0,-400.0,400.0); glMatrixMode(GL_MODELVIEW); glShadeModel(GL_FLAT); glEnable(GL_DEPTH_TEST); } float putaransatu, putarandua = 0; typedef struct{ float x,y; } point2D_t; void drawDot(int x,int y){ glBegin(GL_POINTS); glVertex2i(x,y); glEnd(); } /*void bintang(void) { static int tick=0; static...

Image Processing : Image Enhancement & Grayscale Histogram - PART 1 -

Image
Image enhancement, or image quality improvement is one of the early processes in image processing. Improved image quality is required because often the image being made object have the quality not match as expected. The histogram in the grayscale image represents the distribution of the gray degree in an image. From this histogram can be seen whether the image is more dark color or more bright colors. Look at the picture below. Figure 1. An example of a grayscale image Figure 1 is actually a color image. But in this lab all colored images will be grayscale images. Figure 1 certainly has its own histogram value. Here is the histogram value of Figure 1. Figure 2. Histogram in Figure 1 Figure 2 is a histogram of Figure 1. If the value is seen in the graph, the value distribution is at most between the 30 to 99, so it has a dark dominant color. If you look again, the value above 149 is lower than the value below 149. It can be seen in Figure 1 is more dominant dark co...
