Cem Tugrul — Thu, 17 Nov 2005 05:00:43 GMT

Hi,

i have just set ntp server one of my hp-ux server then started to set ntp clients hp-3600
series WS HP-UX B.10.20 A 9000/785 2010909088 two-user license.They seems Ok means they can
get time from my ntp server but i could not able to set one of it.
manct12 /sbin/init.d > ./xntpd stop
manct12 /sbin/init.d > ./xntpd start
manct12 /sbin/init.d > ps -ef|grep -i xntp
root 7241 5558 0 12:00:27 ttyp1 0:00 grep -i xntp

Problem is xntpd is not working on this WS.
i have checked all necessary files as others
but could not find any difference!!!
Where do i have to look or check on this WS?

Shalom Cem,

See if the ntp.conf file in /etc directory is the same on the working workstation as the one not working.

If not, you may want to copy the good file and then restart xntp.

ntp can be set to auto start as follows:

vi /etc/rc.config.d/netdaemons

XNTPD=1

ntpq -p

# diagnostic test.

Makes sure there are not firewalls between the workstation and the time server.

Before you start xntpd on WS, do as follows and post.

ntpq -p "ntp_server"

If time difference too big to adjust, then xntpd will not work and will exit. To correct this, first set the time manually and then start xntpd. Beaware that setting time backward/forward may upset some apps/progrms-particularly databases.

ntpdate -B "ntp_server"

Hi Cem,

Nice to be close. Someday I'll visit.

Can the workstation have other kinds of network connectivity with the time server?

ping
telnet

etc

Insure network connectivity and report back.

Thanks.

I just remembered,

If the system time is too far off the time server its possible no adjustment will be made at all.

Manually change the workstation to within say half an hour of the time server time, start ntpd service and then run ntpq -p

We should see something.

In ntp.conf, set driftfile and statsdir directives.

start xntpd manually wiith -l option.

xntpd -l /var/adm/ntp.log

Does it give any clue.

Also are required ports opened??
