帶有數據包統計信息的 Nmap

Question

我正在創建應該 ping 雲實例並收集數據包數據的程序，因此為了避免 ping 和不得不打開 ICMP，我們決定使用 NMAP，但挑戰在於使用 NMAP 我不確定哪個選項可以顯示數據包統計信息。

我試過 $nmap -sn hostname 但它沒有產生任何關於數據包的信息。

Answer 1

nmap -sn hostname 命令應該有信息，但它使用 ICMP afaik。 您可以嘗試使用其中一些選項使 ir 更加冗長：

nmap -sn -v3 主機名（這是該命令的更詳細版本，您可以使用 v1 或 v2 來減少冗長的響應）

nmap -sn -d1 主機名（這將返回調試。您可以控制詳細程度，增加數字直到-d6 ）
