Thanks Harlan for your reply.

Why the ntp-dev?

According to this listing:
http://www.eecis.udel.edu/~ntp/ntp_spool/ntp4/

there is a 'stable' version as new as 2004 Jun 17.
I am looking for a simple and reliable solution
to use my existing NTP broadcasts (using Tardis)
to synch up my FreeBSD box.  Using a 'development'
version implies that it hasn't been certified to
be used in a production environment, correct?

Thanks for this procedure list.  I actually did
the following:

# cd /usr/ports/net/ntp/
# make deinstall

(went to /etc/rc.conf and commmented out lines concerning NTP,
then rebooted to disallow the ntpd program from running)

# mkdir ntp-stable-4.2.0a-20040617
cd /usr/ports/distfiles/
#ftp
ftp> open ftp.starhub.net.sg
ftp> cd /pub/funet/unix/tcpip/ntp/xntp/udel/ntp4/
ftp> get ntp-stable-4.2.0a-20040617.tar.gz
ftp> exit
# cp -p ntp-stable-4.2.0a-20040617.tar.gz
/usr/ports/net/ntp/ntp-stable-4.2.0a-20040617/
# cd /usr/ports/net/ntp/ntp-stable-4.2.0a-20040617/
# tar xvzf ntp-stable-4.2.0a-20040617.tar.gz
# mkdir A.x                    # Why 'A.x'?  Would 'temp' work?
# cd A.x
# ../configure
# make
# make install

The 'make install' seemed to go smoothly , but
I cannot find the new executables for NTP.  The 
old ones from 2003 Oct 27 are still in /usr/sbin/.

When I try to find any files modified in the
past day and run:

find ./ -name "*.*" -mtime 1

I don't find 'ntpd' or any other new NTP
related executables.  Does anyone know why 
I can't find the executables, and why the old 
ones are still here?  Where should the new
ones be?

Right.  This is what I have been using in rc.conf:

xntpd_enable="YES"
xntpd_flags="-A -c /etc/ntp.conf -p /var/run/ntpd.pid -l
/var/log/ntpd.log"

Well, I am sure it should be, but I can't find a 
clear, step-by-step procedure for it.  ;^)

Again, Tardis does not have the option for
authentication--as far as I know.

Well, I thought it would be just a simple matter
to get my FreeBSD box to listen to the existing
Tardis NTP broadcasts.  I was hoping to avoid
all the complications of setting up NTP on 
a FreeBSD box to duplicate what Tardis is already
doing.

As an aside, I am very dissapointed that that
there isn't more clear and simple documentation
for FreeBSD/Unix software.  I've found 'man'
pages to be almost useless.  They rarely give
examples, and when they do, they are extremely
complicated.  Criminy, why make it easy for
Bill Gates to keep his stranglehold?
