Java中调用nmap进行主机探测的原理

发布时间:2015/11/30 来源:澳门美高梅官方网站

 在Java中通过调用Runtime这个类可以执行其他的可执行程序,执行后返回一个进程(Process),利用Process这个类我们可以取得程序执行的回显,因此在Java中调用nmap进行主机探测的原理就很清晰了。通过给函数传递nmap所在路径和我们需要执行的命令即可。
 
具体实现代码:
 
/**
* 调用nmap进行扫描
* @param nmapDir nmap路径
* @param command 执行命令
* @return 执行回显
* */
public String getReturnData(String nmapDir,String command){
Process process = null;
StringBuffer stringBuffer = new StringBuffer();
try {
process = Runtime.getRuntime().exec(nmapDir + " " + command);
System.out.println("请稍等。。。");
BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream(),"UTF-8"));
String line = null;
while((line = reader.readLine()) != null){
stringBuffer.append(line + "n");
}
} catch (IOException e) {
e.printStackTrace();
}
return stringBuffer.toString();
}
 
测试:
NmapTest1 nmapTest1 = new NmapTest1();
String str = nmapTest1.getReturnData("D:nmapnmap.exe","-sS -P0 -A -v www.zifangsky.cn");
System.out.println(str);
 
返回结果:
