However, I am facing two problems.Simply, Snort can't do that. You'll need to use something like ethereal's 'follow stream' feature. Stream4 needs to read packets off of the wire to function correctly. It can't do that from a pcap file.
Sounds like it would be useful to take tcpreplay which is a "tool to replay saved tcpdump files at arbitrary speeds".
