Command dissect

The dissect command (alias: dis) allows you to read a fluxzy archive file or a fluxzy dump directory and extract a specific part of it.

Options

Description:
  Read content of a previously captured file or directory.

Usage:
  fluxzy dissect <input-file-or-directory> [command] [options]

Arguments:
  <input-file-or-directory>  A fluxzy file or directory to dissect

Options:
  -i, --id <id>                    Exchange ids, comma separated exchange list
  -f, --format <format>            Specify how to format each matching exchanges to the outputted
                                   result. The default value is "{id} - {url} - {status}"
  -o, --output-file <output-file>  Output the formatted result to a file instead of stdout
  -u, --unique                     Result must be unique or exit error [default: False]
  -?, -h, --help                   Show help and usage information

Commands:
  pcap <input-file-or-directory>  Export pcapng files from an archive or dump directory.

List exchanges

Running the command without the filter id option (-i) will list all exchanges of the fluxzy archive or dump directory with the default formatting ({id} - {url} - {status}).

fluxzy dissect /path/to/archive.fxzy

Or with a dump directory:

fluxzy dissect /path/to/dump-folder

Filtering exchanges

You can use the -i option to filter exchanges by id. If you wish to select multiple exchange ids, you can separate the values with a comma (,).

fluxzy dissect /path/to/archive.fxzy -i "1,2,3"

Formatting output

By default, fluxzy will output the matching exchanges with the default format {id} - {url} - {status}. If you want to display a specific part of the exchange, you can change this default format with the -f option.

For example, the following formatting will output the remote host instead of the url.

fluxzy dissect /path/to/archive.fxzy -i "1,2,3" -f "{id} - {host}"

The possible values of the format are:

Value Description
url The url of the request
method The method of the request
status The status of the response
content-type The content type of the response
authority The authority of the request
path The path of the request
host The host of the request
id The id of the exchange
http-version The http version of the exchange
scheme The scheme of the request
request-body-length The length of the request body
response-body-length The length of the response body
response-body The response body, any transport transformation (gzip, chunk,...) are removed
request-body The request body, any transport transformation (gzip, chunk,...) are removed
pcap The pcap of the connection used by the exchange
pcap-raw The pcap raw of the connection used by the exchange (encrypted)

Filtering on specific fields

To filter on a specific field, you can use the format option (-f) referencing the specific field and use a shell search command (grep, egrep or find for windows) to find the desired entry.

Here a sample to search for all exchanges with a status code 200.

fluxzy dissect /path/to/archive.fxzy -f "{id} - {status}" | grep "200"

Exporting binary data

You can export binary data of an exchange with the dissect command. Binary data can be: request body, response body, pcap and pcap raw. For this you can use the format option with only the field you want to export.

fluxzy dissect /path/to/archive.fxzy -i "1" -f "{response-body}" -o /path/to/output -u

If you don't want the result on standard output, you can use the -o option to specify the output file as in the example above.

Additionally you can use the -u option to abort the command if multiple outputs are found for the specified exchange.

Exporting PCAP files

The pcap subcommand allows you to export pcapng files from an archive or dump directory.

fluxzy dissect /path/to/archive.fxzy pcap -o /path/to/output.pcapng

PCAP export requires that the capture was performed with the --include-dump (-c) option enabled during the start command.
