Question

我需要实现一个能够每秒向一定数量的目的地发送ping数据包的代码。问题是我想在1秒窗口内尽可能多地ping目的地。出于这个原因，我在想是否有办法将循环强制转换为nmap [我的意思是类似于-cycle nmap参数]，这样套接字只能打开一次并在循环ping结束时关闭，从节省的时间比使用“看nmap”的方法！

Answer 1

Nmap项目的一部分是Nping tool。它的设计完全符合您的要求，并且非常易于配置。这是一个示例运行：

$ sudo nping --rate 4 --icmp 192.168.1.4/30

Answer 2

您可以通过以下命令行在命令行中生成多个并行nmap进程：

nmap [options for destination 0] > output0 &

为每个目标生成许多此类nmap请求，同时保持outputX文件的运行索引（output0，output1等）。当您的所有请求都完成后，您可以检查每个输出文件的内容

NMAP连续ping
