Okho banget…

gini gini.. sekarang ni aku lagi mikir gimana caranya bikin network monitoring system sendiri

kemudian setalah pikir2. aku pengen nyoba pake java. karena belom pernah nyoba java hehehe

nah code ini udah ditest n bikin penasaran begadang merenungi pribahasa “Java bisa apa sih?”

import java.io.*;
import java.net.*;

public class ReachableTest {
public static void main(String args[]) {
try {
InetAddress address = InetAddress.getByName(“r1-ska.radio.dishubpku.net”);
System.out.println(“Name: ” + address.getHostName());
System.out.println(“Addr: ” + address.getHostAddress());
System.out.println(“Reach: ” + address.isReachable(3000));
}
catch (UnknownHostException e) {
System.err.println(“Unable to lookup r1-ska.radio.dishubpku.net”);
}
catch (IOException e) {
System.err.println(“Unable to reach r1-ska.radio.dishubpku.net”);
}
}
}

trus dicompile

debian:~# javac ReachableTest.java

trus dijalanin

debian:~# java ReachableTest
Name: r1-ska.radio.dishubpku.net
Addr: 172.16.20.197
Reach: true

trus kok bisa cepet banget ya? ah jadi penasaran.. berapa lama ya kalo 200 host yang dia test?
