tcpick is a textmode sniffer libpcap-based that can track, reassemble and
reorder tcp streams. Tcpick is able to save the captured flows in
different files or displays them in the terminal. It can handle multiple
interface types and is capable of capturing files being transferred by any
protocol, for example FTP or HTTP (with a little post-processing).

I don't promise this will work on 64-bit but if it doesn't you can bug me.
