Run series of PCAPs PCAP file format: [http://wiki.wireshark.org/Development/LibpcapFileFormat]. Thought: might be able to skip the first 24 bytes of each PCAP file and concatenate together (something like what mergecap probably does) without killing RAM.

Yes, it does work, w/ fol cmd: dd if=cap-3of8.pcap bs=1 skip=24 | cat >> /tmp/cap-2of8.pcap

Best way to use it is probably with a named pipe: mkfifo p cat cap-1of8.pcap > p && dd if=cap-2of8.pcap of=p bs=1 skip=24 And then in another window, read 'p' as if it's a PCAP file.

ToolBrief note

SANCP Has proven unreliable for large pcap file analysis. Messes up direction too often to provide good results. Bro connection logger may do better?
