![]() Here's an example run on wget packet capture for this blog, along with a cat for each generated file: $. See Capture Filter Examples for what you can use. tshark_streams.sh capture.pcap "http" it dumps only HTTP streams. There is also an optional argument which is the filter, so if you run it as. bin files to the console if you've captured binary data, use xxd, hexdump, hexedit, or even something like vim. ![]() bin file that stores just the raw stream and nothing else. txt file that contains an ASCII representation of the packet, so that non-printable characters are substituted - unfortunately it also seems to like mixing in packet byte size numbers prefix by a tab before each packet, and it seems this is impossible to disable, so I've also fixed it to generate a. This takes a pcap file generated from wireshark, tshark, tcpdump (or anything that outputs libpcap files) and creates two files for each socket stream. Tshark -r "$1" -qz follow,tcp,ascii,$i > "$1"_stream-$INDEX.txt Tshark -r "$1" -T fields -e data -qz follow,tcp,raw,$i | tail -n 7 | tr -d '=\r\n\t' | xxd -r -p > "$1"_stream-$INDEX.bin STREAMS=$(tshark -r "$1" -T fields -e tcp.stream | sort -n | uniq) STREAMS=$(tshark -r "$1" -R "$2" -T fields -e tcp.stream | sort -n | uniq) Here's the script: #!/bin/bashĮcho "Usage: tshark_strams.sh " Why do all packet capture tools do things you never ask them to do? It took me a while to figure out how to get clean streams using just tshark from pcap files.
