目前,我正在尝试创建的是用户输入范围的ping扫描。

我已经尝试了互联网上的各种资源,但是它们非常模糊,或者我似乎无法使它们正常工作,因此请记住我对Java非常陌生。

我试图完全键入但无法正常工作的一个来源位于-http://www.coderanch.com/t/205721/sockets/java/Determining-computers-network

我尝试使用的代码是...

import java.net.Inet4Address;
import java.net.InetAddress;
import java.util.Arrays;
import java.io.IOException;
import java.io.*;
import java.util.Scanner;
import jpcap.*;
import jpcap.packet.*;

public class ARP{
public static void main(String[] args) throws IOException{

//Obtain the list of network interfaces
NetworkInterface[] devices = JpcapCaptor.getDeviceList();

//for each network interface
for (int i = 0; i < devices.length; i++) {
//print out its name and description
System.out.println(i+": "+devices[i].name + "(" + devices[i].description+")");

//print out its datalink name and description
System.out.println(" datalink: "+devices[i].datalink_name + "(" + devices[i].datalink_description+")");

//print out its MAC address
System.out.print(" MAC address:");
for (byte b : devices[i].mac_address)
System.out.print(Integer.toHexString(b&0xff) + ":");
System.out.println();

//print out its IP address, subnet mask and broadcast address
for (NetworkInterfaceAddress a : devices[i].addresses)
System.out.println(" address:"+a.address + " " + a.subnet + " "+ a.broadcast);
}

//NetworkInterface[] devices = JpcapCaptor.getDeviceList();
int index =1; // set index of the interface that you want to open.

//Open an interface with openDevice(NetworkInterface intrface, int snaplen, boolean promics, int to_ms)
final JpcapCaptor captor=JpcapCaptor.openDevice(devices[index], 65535, false, 20);









//JpcapCaptor captor=JpcapCaptor.openDevice(device[1], 65535, false, 20);

//call processPacket() to let Jpcap call PacketPrinter.receivePacket() for every packet capture.
//captor.processPacket(10,new PacketPrinter());
//System.out.println(packet);
//captor.close();

}
}


上面的代码在我尝试使用它时有很多错误,不能完全确定我在做什么错。

同样,我对Java还是很陌生,如果有人可以指出正确的方向,那将对您有很大的帮助。

我也尝试过使用这个YouTube教程,该教程涵盖了端口扫描和Ping扫描,但是运气不佳。

任何帮助将不胜感激,

谢谢,

我从这里https://stackoverflow.com/a/14110872/868040获得的这段代码可对设备执行ping操作。您可以轻松地对此进行修改以对一系列设备执行ping操作。

import java.io.*;
import java.util.*;

public class JavaPingExampleProgram
{

  public static void main(String args[])
  throws IOException
  {
    // create the ping command as a list of strings
    JavaPingExampleProgram ping = new JavaPingExampleProgram();
    List<String> commands = new ArrayList<String>();
    commands.add("ping");
    commands.add("-c");
    commands.add("5");
    commands.add("74.125.236.73");
    ping.doCommand(commands);
  }

  public void doCommand(List<String> command)
  throws IOException
  {
    String s = null;

    ProcessBuilder pb = new ProcessBuilder(command);
    Process process = pb.start();

    BufferedReader stdInput = new BufferedReader(new InputStreamReader(process.getInputStream()));
    BufferedReader stdError = new BufferedReader(new InputStreamReader(process.getErrorStream()));

    // read the output from the command
    System.out.println("Here is the standard output of the command:\n");
    while ((s = stdInput.readLine()) != null)
    {
      System.out.println(s);
    }

    // read any errors from the attempted command
    System.out.println("Here is the standard error of the command (if any):\n");
    while ((s = stdError.readLine()) != null)
    {
      System.out.println(s);
    }
  }
