获取客户端的IP地址或获取连接到热点的Andr​​oid客户端的信息（SSID）（圈养后） [英] Getting the IP address of client or getting the information(SSID) of Clients connected to Hotspot Android (after Tethering)

问题描述

我得到了，我得到了一个开放式（非加密）热点的Andr​​oid程序的无线网络共享。我喜欢观看客户端（SSID和IP地址）的连接到我的热点的细节。 我用SocketAddress的socketid = socket.getLocalSocketAddress（）;同时还采用

 公共无效getLocalIpAddressString（）{
   尝试 {
       对于（枚举＆LT;的NetworkInterface＆GT; EN = NetworkInterface.getNetworkInterfaces（）; en.hasMoreElements（））{
          NetworkInterface的INTF = en.nextElement（）;
          对于（枚举＆LT; InetAddress类＆GT; enumIpAddr = intf.getInetAddresses（）; enumIpAddr.hasMoreElements（））{
                InetAddress类InetAddress类= enumIpAddr.nextElement（）;
               如果（！inetAddress.isLoopbackAddress（））{
                   //返回inetAddress.getHostAddress（）的toString（）。
                    Toast.makeText（getApplicationContext（），inetAddress.getHostAddress（）的toString（）
                            Toast.LENGTH_SHORT）.show（）;

                }
           }
        }
    }赶上（例外前）{
      Log.e（IPADDRESS，ex.toString（））;
   }
  //返回null;
   }
 

这些只会返回本地IP，但你可以请帮我在得到客户端连接到我的WiFi热点的IP地址。谢谢你。

解决方案

最后，我得到了获取客户端IP连接到我的热点响应

。下面的code将跟踪Mac和新的客户端添加到我的网络每次IP更改

 公共无效getClientList（）{

    INT macCount = 0;
    的BufferedReader BR = NULL;
    尝试 {
        BR =新的BufferedReader（新的FileReader（的/ proc /净/ ARP））;
        串线;
        而（（行= br.readLine（））！= NULL）{
            串[]分裂= line.split（+）;

            如果（分裂= NULL和放大器;！＆安培; splitted.length＆GT; = 4）{
                //基本的完整性检查
                串MAC =分裂[3];

                如果（mac.matches（..：..：..：..：..：..））{
                    macCount ++;
                    ClientList.add（客户端（+ macCount +））;
                    IpAddr.add（分裂[0]）;
                    HWAddr.add（分裂[3]）;
                    Device.add（分裂[5]）;
                    Toast.makeText（
                            getApplicationContext（），
                            Mac_Count+ macCount +MAC_ADDRESS
                                    + MAC，Toast.LENGTH_SHORT）.show（）;
                    的for（int i = 0; I＆LT; splitted.length;我++）
                        的System.out.println（Addressssssss
                                +分裂[I]）;
                }
            }
        }
 

I got the program for Wifi tethering which i got a open (non secured) hot spot in Android. I like to view the details of client (SSID and IP address) connected to my hotspot. I used SocketAddress socketid=socket.getLocalSocketAddress(); and also used

public  void getLocalIpAddressString() {
   try {
       for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();) {
          NetworkInterface intf = en.nextElement();
          for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) {
                InetAddress inetAddress = enumIpAddr.nextElement();
               if (!inetAddress.isLoopbackAddress()) {
                   // return inetAddress.getHostAddress().toString();
                    Toast.makeText(getApplicationContext(), inetAddress.getHostAddress().toString(),
                            Toast.LENGTH_SHORT).show();

                }
           }
        }
    } catch (Exception ex) {
      Log.e("IPADDRESS", ex.toString());
   }
  // return null;
   }

These will return only the local IP but can you please help me in getting the IP address of client connected to my Wifi Hotspot. Thank you.

解决方案

Finally I got the response for getting the Client IP connected to my hotspot. The code below will track the Mac and IP changes each time a new client is added to my network

public void getClientList() {

    int macCount = 0;
    BufferedReader br = null;
    try {
        br = new BufferedReader(new FileReader("/proc/net/arp"));
        String line;
        while ((line = br.readLine()) != null) {
            String[] splitted = line.split(" +");

            if (splitted != null && splitted.length >= 4) {
                // Basic sanity check
                String mac = splitted[3];

                if (mac.matches("..:..:..:..:..:..")) {
                    macCount++;
                    ClientList.add("Client(" + macCount + ")");
                    IpAddr.add(splitted[0]);
                    HWAddr.add(splitted[3]);
                    Device.add(splitted[5]);
                    Toast.makeText(
                            getApplicationContext(),
                            "Mac_Count  " + macCount + "   MAC_ADDRESS  "
                                    + mac, Toast.LENGTH_SHORT).show();
                    for (int i = 0; i < splitted.length; i++)
                        System.out.println("Addressssssss     "
                                + splitted[i]);
                }
            }
        }
