Anyone knows if there are any available Linux based S/W to test the

I.E:
packets per second?
% of lost packets
etc?

I hope not. I can just see someone deciding to test one of the stratum 1
main servers (eg at the usno) Why in the world would you want this?
Sigh! I'm sure it has happened and will happen again! I'm sure that
there are people complaining to the National Bureau of Standards or
the Naval Observatory that their time is incorrect! ;-)
If you really want time with better than micro-second accuracy, consider
get a GPS Timing receiver. The one I bought several years
ago claimed 50 nanosecond plus or minus of the correct time.
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.
