customscanthread.java

本程序是是用Java写的端口扫描器,Xml做配置文件,能自定义端口

package src;

import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.Socket;
import java.net.SocketAddress;

public class CustomScanThread extends Thread {
	private int port_num;
	private Socket s;
	private int i;
	
	public CustomScanThread(int port_num){
		this.port_num=port_num;
	}
	
	public void run() {
		while(ScannerGUI.sum_1 < port_num){
			s=new Socket();
			i=Integer.parseInt((String)ScannerGUI.list.get(ScannerGUI.sum_1));
			SocketAddress soc=new InetSocketAddress(ScannerGUI.getIPAddress(),i);
			try {
				s.connect(soc,2000);
				ScannerGUI.textArea.setText("开放端口:"+i+"\n");
			} catch (IOException e) {

			}
			ScannerGUI.d.progressBar.setValue(ScannerGUI.sum_1);
			if(ScannerGUI.d.progressBar.getValue()==ScannerGUI.d.progressBar.getMaximum()){
				if(ScannerGUI.d!=null){
					ScannerGUI.d.toggleButton.setEnabled(true);
				}else{
					
				}
			}
			ScannerGUI.add1();
		}
		ScannerGUI.d.toggleButton.setEnabled(true);
	}
}
