NTP Survey 1999 code

The files here are the code from my NTP survey of 1999. For more information, please see the paper.

The code here is not intended for others to run, it was not designed for reusability. Instead, it is provided here for others to reed to see how the NTP survey was conducted and maybe take ideas for implementing further surveys.

Please contact me if you intend to actually use any of this code.

• NTPSpider.java, the actual spider class, tracks where its gone and where to go.
• WorkerPool.java, an abstraction for multithreading the work.
• QueryServer.java, a single worker, handles calling xntpdc.
• Host.java, data object for one host. A small amount of IP address parsing code was borrowed from JDK sources.
