Synchronize time HP-UX with Windows 2000

[Robson Menezes]

We have tree HP-UX Servers and one Windows 2000 Server. How Can I synchronize the time HP-UXs with Windows 2000?

HP-UX nameserver B.11.00 A 9000/712
Windows 2000 Server is the Master Server Time.

I tried the NTP Daemon and put the lines on ntp.conf:

server nameserver version 3 prefer
broadcast version 3

But it didin´t work.

Please post output of:

ntpq -q

or

ntpq -p

I forget which.

Windows 2000 Servers standard time server is not ntp standards compliant and can not be used as a time source for HP-UX.

Patching is required to make it compliant.

Hi Robson,

I have prepared a step-by-step guide for you: How to synchronize time of HP-UXs with Win2K :-)

Sincerely,

ewwww, there's a few things to say here.

windows 2000 is using SNTP (S as in 'Simple')

- it doesn't know how to send broadcasts
- it doesn't know how to receive broadcasts

broadcast is the statement to *send* broadcasts, but the IP of the windows server of course is no broadcast address.

What You want is done by simply saying
server version 3

Notes:
- Windows is not good at timekeeping, and Unix is very critical about time, so this might not be a very good idea and unless You chose to run the NTP distribution on the windows host, You won't get broadcast to work
- the correct statement to let hp-ux listen for broadcasts is
broadcastclient
- rather use multicast

Wow, Hakan, I just looked at Your pdf -
great idea for a walkthrough!

Hi Robson,

Verify /etc/rc.config.d/netdaemons file.

export NTPDATE_SERVER=sntp.domain.net
export XNTPD=1
export XNTPD_ARGS=

My dears friends...thank´s for all!
I`m sorry but my English isn´t good. It´s not my first language :-)

I did all the steps by Hakan´s PDF, but didn´t work.
After the PDF I made some things.
My procedures...
1. Netdaemons file
/etc/rc.config.d/netdaemons

export NTPDATE_SERVER=
XNTPD=1
export XNTPD_ARGS=

2. ntp file
/etc/ntp.conf
broadcastclient yes
server nameserverWin2000 version 3
driftfile /etc/ntp.drift

3. Run xntpd
/sbin/init.d/xntpd start

After that...ERRO
root@suport:/etc =>/sbin/init.d/xntpd start

4. ntpd tests

Ahh...where has nameserverWin2000...is the name of the Windows 2000 Server.Ok

HELP ME!
Thanks > Obrigado!

Robson,

I'm are going to give this a shot.

First off I agree with SEP and Florian that Windows doesn't use the same ntp tha HP-UX does.

As you can see in your test 3 and test 4 "no server suitable for synchronization found" means exactly that. I don't believe that Windows can do a broadcast, without 3rd party software, but it can do a receive. If you want to look at 3rd party software I would suggest that you look at Tardis 2000 located at
http://www.kaska.demon.co.uk/tardis.htm

It has the capability to get the time from atomic clocks on the internet AND do a broadcast (not worked with that part).

We sync our HP-UX servers to the atomic clocks using the ntp that is provided as part of HP-UX, broadcast the tiime on our intranets and then have the pc's and I believe the Windows servers also sync to that signal with no additional software on either of them. This,unfortunately, is just the opposite of what you want to do.

If you MUST sync your HP-UX to the Windows you might try Tardis above.

There are free servers for NT/2000/2003 that actually comply with Unix standards.

Thank you!!!
I´m going to try now.
I think that the problem is the port 123 (Windows 2000).
See you...
