[comp.protocols.tcp-ip] Time server

kdenning@pcserver2.naitc.com (Karl Denninger) (03/01/91)

Hi!

I'm looking for the source code to the Internet time server program.  The
MIPS systems we have here have a thing called "timed", and the Suns have 
"rdate".  Both of these appear to be proprietary to their respective
machines.

I would like to be able to synchronize all the clocks in our domain using
this.... including PCs.  Beame and Whiteside has the ability to query one on
demand, if I can find the Unix-side code!

Thanks in advance for pointers or code!

UNIX Review, Vol 8 No 12 says, in the Daemons and Dragons column, that RFC
1129 covers Network Time Protocols.  The article describes the time service
reasonably clearly, I think.  According to the author, he/they use xntpd
"written by Dennis Ferguson at the University of Toronto."  "To obtain the
xntp implementation of the NTP protocol, use anonymous ftp to louie.udel.edu
and look in the directory ~ftp/pub/ntp/xntp.  The distribution consists of 
a 49 KB compressed tar archive.  The distribution takes approximately 10
minutes to build on a Sparcstation 1." [typos, if any, are mine]
