DHCP server with NAT

Posted on June 7, 2015June 25, 2015 by coder

# DHCP Client

#1. DHCP sunucusuna giren adamin, ping atabilmesi icin, asagidaki komutu yazmasi gerekir. NAmeserver olarak dhcp sunucusunu vermesi gerekir.

nameserver 172.20.0.1
# bunu yazdiktan sonra ping atiyor. ama Dosya indiremiyor.

DHCP SERVER

# If the client wants to connect internet, The DHCP server should enable ip forwarding, after that

should SET default GATeway to NAT router GW.

Aspect-oriented programming

Posted on June 6, 2015June 7, 2015 by coder

An aspect is a common feature that’s typically scattered across methods, classes, object hierarchies, or even entire object models.

Express this structure in code with traditional object-oriented techniques.

For example, let’s say you wanted to add code to an application to measure the amount of time it would take to invoke a particular method. In plain Java, the code would look something like the following.

public class Account
{
    public void Calculate(double amount)
    {
         long startTime = System.currentTimeMillis();
         try
         {
            // Actual method body...
         }
         finally
         {
              long endTime = System.currentTimeMillis() - startTime;
              System.out.println("Draw Actual area," + endTime);
         }
    }
}

public class Account

{

public void Calculate(double amount)

{

long startTime = System.currentTimeMillis();

try

{

// Actual method body...

}

finally

{

long endTime = System.currentTimeMillis() - startTime;

System.out.println("Draw Actual area," + endTime);

}

Implementing metrics in a AOP Interceptor

 public class Metrics implements org.jboss.aop.advice.Interceptor {
   public Object invoke(Invocation invocation) throws Throwable
   {
     long startTime = System.currentTimeMillis();
     try
     {
       		return invocation.invokeNext();
				// if  return fails,   Test it your self. 
     }
     finally
     {
		   long endTime = System.currentTimeMillis() - startTime;
		   java.lang.reflect.Method m = ((MethodInvocation)invocation).method;
		   System.out.println(" Our kutays methods  end :  " + m.toString() + " time: " + endTime + "ms");
     }
   }
 }

public class Metrics implements org.jboss.aop.advice.Interceptor {

public Object invoke(Invocation invocation) throws Throwable

{

long startTime = System.currentTimeMillis();

try

{

return invocation.invokeNext();

// if return fails, Test it your self.

}

finally

{

long endTime = System.currentTimeMillis() - startTime;

java.lang.reflect.Method m = ((MethodInvocation)invocation).method;

System.out.println(" Our kutays methods end : " + m.toString() + " time: " + endTime + "ms");

}

Example Return for result in controller

Posted on May 28, 2015June 4, 2015 by coder

Controller.cs

                // Index.aspx   << View has ViewResult 
        public ViewResult Index()
        {
            String asd= Request.Params.Get(0);
            int hour = DateTime.Now.Hour;
            ViewData["kutay_variable"] = (hour < 12 ? "morning" : "afternoon");
            return View();
        }

Controller.cs

// Index.aspx << View has ViewResult

public ViewResult Index()

{

String asd= Request.Params.Get(0);

int hour = DateTime.Now.Hour;

ViewData["kutay_variable"] = (hour < 12 ? "morning" : "afternoon");

return View();

}

Inside of View page,

 <%=ViewData["kutay_variable"]%>

>>> Out put is   morning or afternoorn

<%=ViewData["kutay_variable"]%>

>>> Out put is morning or afternoorn
