go-flows filtering omits packet #21

@Wistm

Description

@Wistm

attached files:

  • wrongFilteringGoFlows.pcap: Unfiltered pcap with two flows in there.
  • write_pcap.json: go-flows configuration file

used command:

  • ../go-flows run features ../write_pcap.json export ipfix test.pcap source libpcap wrongFilteringGoFlows.pcap (dependent on the used folder structure)

Following that, a folder structure is created with two folders. Within folder "0", there lies the filtered "0.pcap".

Detected problem:

  • packet 135 in wrongFilteringGoFlows.pcap corresponds to packet 69 in 0.pcap
  • packet 134 in wrongFilteringGoFlows.pcap is not present in 0.pcap although it should be there because it belongs to the same flow.
