//获取网卡地址
  private String getMacAddress(String remotePcIP){
      String str="";
      String macAddress="";
      try {
           Process pp= Runtime.getRuntime().exec ("nbtstat -A " + remotePcIP);
           InputStreamReader ir = new InputStreamReader(pp.getInputStream());
           LineNumberReader input = new LineNumberReader (ir);
           for (int i = 1; i <100; i++)
              {
               str=input.readLine();

关键在于nbtstat 的参数,可在dos 下运行nbtstat看看
物理地址???你是说MAC(媒体访问控制)地址吗?
