A newer tool called tcpflow complements tcpdump and provides a way to do protocol flow analysis and to properly reconstruct data streams, regardless of packet order or retransmissions.

You can also try the cross-platform tcpdump tool, which is supported on most UNIX and Linux operating systems.

您也可以尝试使用跨平台的tcpdump工具，它支持大多数的UNIX和Linux操作系统。

Another way to process the content from tcpdump is to save the raw network packet data to a file and then process the file to find and decode the information that you want.

处理来自tcpdump的另一个方法是将原始网络数据包数据保存到一个文件中，然后处理这个文件以便查找和解码出您想要的信息。
