Scapy 中是否有一个选项：only_summaries？

Question

我正在用 Scapy 处理一个巨大的 pcap 文件，但是速度很慢。

当我计划用 Pyshark 重构它时，我发现有一个名为 'pyshark.FileCapture()' 的函数提供了一个选项：only_summaries.

这就是我想要的。那么，Scapy中是否也有任何选项或方法？

Answer 1

不，它没有。我在 github 上得到了 gpotter2 的回答，他是 scapy 的负责人之一。

见https://github.com/secdev/scapy/issues/1509

If you want to perform the better, you can use with

PcapReader(filename) as reader:
    for pkt in reader:
        [... actions on  the pkt ...] You can store specific informations on the packet that you want, or directly perform actions

on the packet. But scapy does not have a only_summaries by itself: scapy would have to dissect the packet anyways, before returning only some few informations
