SCO Unix and ntpdate

[Joel Hammer]

No solutions, just some observations. I don't use w2k.
This is from the documentation for ntp:

	ntpdate: Directory containing sources for a program to set the
	local machine time from one or more remote machines running NTP.
	Operates like rdate, but much more accurate.

I can get your error when I run ntpdate against an XP pro box and against a
linux box which is not running ntp. But, it works fine with a linux box
running xntpd. However, when I turned off the xntp daemon, then
turned it back on, it took several minutes for the server to come up to full
speed before it started to accept requests from ntpdate from my client, even
though xntpd was running fine on the server.

So, is the Win2K server running the ntp daemon?  Do any other clients
connect successfully? Maybe it is running a timeserver daemon on port 37? (rfc 868).
Do you have the equivalent of netstat -anp on the win2k box?

ntp can be configured to serve only certain hosts or networks. How is the
win2k box configured?

Also I might ask, why do you want to run ntpdate? Why not just run the
xntpd daemon on your Unix box and be syncronized to within milliseconds?
Once it is set up, it works without any problems (so far.)
