[tcpdump-workers] extracting tcpdump data

[Rusma Mulyadi]

I am looking for tools/ scripts that can be use to preprocess tcpdump file.  For the tcp packets, I wanna be able to extract the connection level information about the network traffic (e.g. start time, duration, participating hosts and ports, etc.) for further processing using data mining tool. Any comments and inputs are very welcome. Thanks, Rusma
