usage: pdml2flow [-h] [-f FLOW_DEF_STR] [-t FLOW_BUFFER_TIME] [-l DATA_MAXLEN]
                 [-s] [-x] [-c] [-a] [-m] [-d]

Aggregates wireshark pdml to flows

optional arguments:
  -h, --help           show this help message and exit
  -f FLOW_DEF_STR      Fields which define the flow, nesting with: '.'
                       [default: ['vlan.id', 'ip.src', 'ip.dst', 'ipv6.src',
                       'ipv6.dst', 'udp.stream', 'tcp.stream']]
  -t FLOW_BUFFER_TIME  Lenght (in seconds) to buffer a flow before writing the
                       packets [default: 180]
  -l DATA_MAXLEN       Maximum lenght of data in tshark pdml-field [default:
                       200]
  -s                   Extract show names, every data leave will now look like
                       { raw : [] , show: [] } [default: False]
  -x                   Switch to xml output [default: False]
  -c                   Removes duplicate data when merging objects, will not
                       preserve order of leaves [default: False]
  -a                   Instaead of merging the frames will append them to an
                       array [default: False]
  -m                   Appends flow metadata [default: False]
  -d                   Debug mode [default: False]

Example

Sniff from interface:

$ tshark -i interface -Tpdml | pdml2flow

Write xml output

$ tshark -i interface -Tpdml | pdml2flow -x

Read a .pcap file

$ tshark -r pcap_file -Tpdml | pdml2flow

Aggregate based on ethernet source and ethernet destination address

$ tshark -i interface -Tpdml | pdml2flow -f eth.src -f eth.dst

Pretty print flows using jq

$ tshark -i interface -Tpdml | pdml2flow | jq

Post-process flows using FluentFlow

$ tshark -i interface -Tpdml | pdml2flow | fluentflow rules.js
