Allows access decisions to be made external to the applications. I.e. security inside of the app server container. introduces a 15-20% performance hit.
One option: dump to pcap-ng (use -P to dump in the earlier libpcapc) - then convert for chaosreader
dumpcap -i wlan0 -w file.cap
Pcap-NG (aka NTAR). This format allows for more advanced features than the old libpcap (aka PCAP) format, such as multiple interface types and annotations.
