当我使用命令行使用Tshark捕获时，如何限制数据包大小

Question

目前我的命令是tshark.exe -i（int interface）-V -x -w C：\ file.pcap但我无法找到我应该添加的内容以限制数据包大小

Answer 1

您可以使用-s capture snaplen选项。

-s capture snaplen
    Set the default snapshot length to use when capturing live data. No more than snaplen bytes of each network packet will be read into memory, or saved to disk. A value of 0 specifies a snapshot length of 65535, so that the full packet is captured; this is the default.
    This option can occur multiple times. If used before the first occurrence of the -i option, it sets the default snapshot length. If used after an -i option, it sets the snapshot length for the interface specified by the last -i option occurring before this option. If the snapshot length is not set specifically, the default snapshot length is used if provided.
