Try to squeeze all in the json buffer
Try to import bulk buffer

Problem: libcurl hangs?
seperate command from data
srcaddr and dstaddr did not existed in mapping
Added v4 as suffix
Program still hangs
Changed default index settings
enabled bulked import
Fixed timestamp to be accepted by elastic search

TOFIX Millis are ignored
Added millis for the firstseen timestamp
Add also millis for lastseen timestamp
leading zeros are needed for millis otherwise exceptions are thrown
First stress test
