带有数据包统计信息的 Nmap

Question

我正在创建应该 ping 云实例并收集数据包数据的程序，因此为了避免 ping 和不得不打开 ICMP，我们决定使用 NMAP，但挑战在于使用 NMAP 我不确定哪个选项可以显示数据包统计信息。

我试过 $nmap -sn hostname 但它没有产生任何关于数据包的信息。

Answer 1

nmap -sn hostname 命令应该有信息，但它使用 ICMP afaik。 您可以尝试使用其中一些选项使 ir 更加冗长：

nmap -sn -v3 主机名（这是该命令的更详细版本，您可以使用 v1 或 v2 来减少冗长的响应）

nmap -sn -d1 主机名（这将返回调试。您可以控制详细程度，增加数字直到-d6 ）
