# Client's sensors in database are created dynamically by server's sensor.
# Communication between server/client is encrypted.
# Can be only one server's sensor for now, the other sensors must be clients. Old fashioned remote sensors can be used together.
# Implicitly, client process a data, saves a pcaps to a local spooldir, sent the sql inserts/queries to the server's sensor
# and server's sensor does the whole sql operations. So on client side isn't needed any sql setting.
# Modification of this process can be done in client configuration.

# temporarily slow the sender will not loose single packet. The mirroring is trying to reconnect in case of 
# failure. Packets are mirrored including the the original timestamp and headers. 
# this mirroring hopefully replaces pcapscandir feature which will be probably removed in favor of this approach.
