network time protocol

[Animesh Chakraborty]

Hi ,
I am using NTP to synchronise the time among servers.Will there be any problem synchronising time with hp-ux 11.00(server) to 10.20 client ?

Thanks
Animesh

Hi,

NTP is a protocol. This protocol uses different devices like routers, servers, ... You can synchronize time on all devices which support NTP.

Yes you can synchronize time yours client on HP-UX 10.20 with server on HP-UX 11.00.

Hi Animesh,

As NTP is a widely used protocol, you may use it to synchronize nearly all systems, from different brands and O/S type.

If this wasn't possible, you wouldn't be able to synchronize to an internet stratum 1 or 2 if it wasn't the same equipment as yours.

We use it between HP-UX 10.20, 11.0 , Windows NT, Novell Netware, AIX and SOLARIS.

It works like a charm.

Best regards,

Dan

I agree that it works 10.20 and 11.00.

Connect the SEWRVER to an Atomic Clock Signal from the WEB or an Hardware Device.
Poor man's version:
Buy an ATC clock and place on your desk and verify the time on the server.

Broadcast the time.

Time intervals are platform, class, and mpc code dependant.

DO NOT TURN BACK the time on an ACTIVE DATABASE!

I have one K580 that drifts but, the others are godd for ONCE a day.

Because it works, information is vague from HP.

We use ntp in a mix of HP-UX 11.00, 10.20 and Sun Solaris 2.6. Works great and I highly recommended you use it. Keeping time sync'ed is now one less thing an admin needs to worry about.

Hi
Thanks a lot for your inputs.Its working fine with 10.20 client.
Another problem : I am unable start xtpd demon in one client.
#/sbin/init.d/xntpd start
gives mesg in syslog :xntpd[29020]: bind() fd 11, family 2, port 123, addr ca2a25ff, in_classd=0 flags=0 fails: Address already in use.
#ntpq -c rv
ntpq: read: Can't assign requested address
Can any one suggest how to start it now without rebooting the server?
Thanks
Animesh

Hi:

Make sure you don't have 'ntpdate' running. It uses the same port as 'xntpd'. Also make sure 'xntpd' isn't already running, either.

Hi,
The ntpdate and xntpd are not running.
When I try to stop it ,gives following mesg.
#/sbin/init.d/xntpd stop
#ERROR: Unable to stop xntpd (cannot find pid)

thanks
