The NTP server we will be testing will be connected to a Cesium clock
providing a 1pps pulse so that is really not my problem.
I want to check if this system can handle DDoS attacks, and bad packets.
This will be done in a lab environment, possibly point-to-point from
the test machine, to the server, or maybe
In order to test DDoS, probably some FPGA H/W is needed to generate good
packets, and the S/W stuff is there to generate bad packets and
check how the server reacts to those
Recording the packets will be done with FPGA H/W as well.
