Metron: ingest PCAP files

msumbul1 — Fri, 15 Sep 2017 20:20:45 GMT

Hi,

I saw that it's possible to use pycapa script in order to capture data and send it to kafka.
Do you know if there's an easy way to directly ingest pcap file that has been generated by another system? Like a program that read the pcap file and send it to kafka? Or another manner to do it?

Thanks

Michel

Yes, we do that a lot for testing.

First, use a tool like 'tcpreplay' to replay a pcap file to a network interface. There is even a simple tool in Metron (https://github.com/apache/metron/tree/master/metron-deployment/roles/pcap_replay) that effectively wraps 'tcpreplay' to make it easy to replay packet captures to a virtual network interface.
Then use 'pycapa' in producer mode to sniff the packets from that network interface and land them in Kafka.

@nallen

The pcap_replay is install as a service by default with HCP 1.2? If not, how to install it manually?

Thanks
