Un ottimo scanner di rete in JAVA che ho trovato; ho lasciato, giustamente, le licenze all\'interno del codice:
Pscan.java
import java.io.*;
import javax.swing.Timer;
import java.net.*;
import java.util.*;
import java.lang.Thread;
public class Pscan
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);
System.out.print(\"\\nAD ASTRA! PortScanner 2.0 2008\\nCreated By eddiewrc\");
System.out.print(\"\\nTarget IP address: \");
String ip = in.next();
System.out.print(\"\\nStart at port: \");
int start = in.nextInt();
System.out.print(\"\\nFinish at port: \");
int finish = in.nextInt();
System.out.print(\"\\nNumber of Threads (50 < Suggested < 100): \");
int trd = in.nextInt();
System.out.print(\"\\nStart scanning... \\n\");
Thread[] socks = new Thread[trd];
class ScanThread extends Thread
{
ScanThread(String ip1, int i)
{
porta = i;
ip = ip1;
}
public void run() {
try
{
Socket s = new Socket(ip, porta);
System.out.println(\"Port: \" + porta + \" Status: OPEN\");
}
catch (IOException ex)
{
//System.out.println(\"Port: \" + porta + \" Status: CLOSE\");
this.stop();
}
}
private int porta;
private String ip;
}
int i, j;
StopWatch time = new StopWatch();
time.start();
for (i = start; i < finish; )
for (j = 0; j < trd; j++, i++)
{
socks[j] = new ScanThread(\"127.0.0.1\", i);
socks[j].start();
}
time.stop();
System.out.println(\"Scan finished at port: \" + i);
System.out.println(\"Scan time: \" + time.getElapsedTimeSecs() + \" secs\");
}
}
StopWatch.java
public class StopWatch {
private long startTime = 0;
private long stopTime = 0;
private boolean running = false;
public void start() {
this.startTime = System.currentTimeMillis();
this.running = true;
}
public void stop() {
this.stopTime = System.currentTimeMillis();
this.running = false;
}
//elaspsed time in milliseconds
public long getElapsedTime() {
long elapsed;
if (running) {
elapsed = (System.currentTimeMillis() - startTime);
}
else {
elapsed = (stopTime - startTime);
}
return elapsed;
}
//elaspsed time in seconds
public long getElapsedTimeSecs() {
long elapsed;
if (running) {
elapsed = ((System.currentTimeMillis() - startTime) / 1000);
}
else {
elapsed = ((stopTime - startTime) / 1000);
}
return elapsed;
}
/*//sample usage
public static void main(String[] args) {
StopWatch s = new StopWatch();
s.start();
//code you want to time goes here
s.stop();
System.out.println(\"elapsed time in milliseconds: \" + s.getElapsedTime());
}*/
}
