Time syncronization

Patrick Chim — Thu, 08 Mar 2001 02:02:27 GMT

Hi all,

1. May I ask how to syncronize the time between two HP servers running HP-UX 11.0 ?
2. Does HP provide any software or is there any freeware on the internet so that I can syncronize the time between an HP server and a RedHat server no matter they are on the same subnet or not (of course they can telnet to each other)?

Thank you for your kind attention !

Patrick

Patrick, what you want to do is to run ntp. there have been a number of discussions on the forums on configuring ntp - do a search in the forums for ntp -to start you off check:

redhat also supports ntp - you would have to download the rpm file for xntp

good luck

Well xntpd is available on 11.0 and you should be able to set it up using SAM. HP now includes xntp as standard distribution with the OS. From the man page:
xntpd is a daemon which maintains a UNIX system's time-of-day in agreement with Internet standard time servers.

Hi Patrick,

Just a quick start for you. Let say you got two servers called "time_server" and "time_client", and that you want "time_client" to sync. with the system time of "time_server".

Steps,

1. in time_server, create the file /etc/ntp.conf containing the line "server 127.127.1.1"

2. in time_client, create the file /etc/ntp.conf containing the line "server time_server version 3"

3. to both time_server and time_client, edit the file /etc/rc.config.d/netdaemons, change the XNTPD varible to 1.

4. to both time_server and time_client, start xntpd (network time protocol daemon) by entering "/sbin/init.d/xntpd start"

Then time_client will start to synchronize with time_server.

Rgds,
Philip

To add u can use more than 1 time server over internet to increase the level of accuracy .
Startum 1 servers are said to be the most accurate servers.There are even hardware available which you can install in the host and get the time relayed by a GPS or a radio resource.
