Hi

I have an annoying problem with ntp on AIX 5.3 TL7. This is what I
did:
1. I have enabled start of xntpd in /etc/rc.tcpip
2. /etc/ntp.conf looks like this:

server <my ntp server ip>
broadcastclient

driftfile /etc/ntp.drift
tracefile /etc/ntp.trace

3. I run ntpdate <my ntp server ip>
4. Finally, I run startsrc -s xntpd

The subsystem has started and runs just fine without a crash. The time
is correct, the date is correct, the time zone is good (I set it
earlier). There is no error regarding to xntp src. But...
The xntpd does not start after reboot. After reboot the date and time
are still correct and seem to be synchronized. But xntpd subsystem is
inoperative. After every reboot I have to start it manually. Then I
run ntpq -p and the output is like this:

remote refid st t when poll reach delay
offset disp
================================================== ============================
*x.x.x.x x.x.x.x 4 u 94 128 377 1.16 -0.367
0.12

So the offset is not the issue. After reboot there is no error in
errorlog and after starting src manually ntp runs just fine without
the crash.
Am I doing something wrong or what? Why xntpd doesn't start after
reboot? I have thi issue on all my LPARs in p595 server, firmware
version SF240_320. I will appreciate any help, thanks in advance

Check the conslog to check whether or not you see a messages for the
xntpd during boot.
From memory
$ alog -f /var/ras/adm/conslog -o

or put even an lssrc -s xntpd right after the start of the xntpd

Try strating the xntpd daemon at system boot by putting the following
entry in /etc/inittab
xntp:2nce:/usr/bin/startsrc –s xntpd > /dev/console 2>&1
I suppose xntpd doesn't get initialized through rc.tcpip. Pls correct
if I am wrong.

Conslog is clear, adding xntp:2nce:/usr/bin/startsrc -s xntpd > /dev/
console 2>&1 to inittab makes no effect, hovever when I put xntp:
2:respawn:/usr/bin/startsrc -s xntpd > /dev/console 2>&1 to inittab
and restart, the message has occured in /var/adm/ras/conslog:

INIT: Command is respawning too rapidly. Check for possible errors.
id: xntp "/usr/bin/startsrc -s xntpd /dev/console 2>&1"

The xntp subsystem was still inoperative. So, it seems the xntp is
starting and stopping very fast. But whty is it stopping? I put all
facilities in all priority levels in syslog but after restart there is
no entry in log file. There also are no errors in bootlog or errorlog.
After starting inoperative system manually the entry shows in syslog:

Apr 22 11:07:36 piwmbtdev daemon:notice xntpd[327904]: 3.4y
Apr 22 11:07:36 piwmbtdev daemon:notice xntpd[327904]: 3.4y
Apr 22 11:07:36 piwmbtdev daemon:notice xntpd[327904]: tickadj = 1000,
tick = 10000, tvu_maxslew = 99000
Apr 22 11:07:36 piwmbtdev daemon:notice xntpd[327904]: tickadj = 1000,
tick = 10000, tvu_maxslew = 99000
Apr 22 11:07:36 piwmbtdev daemon:info xntpd[327904]: precision = 6
usec

But I see no errors here either Is that possible the xntp starts at
reboot time, synchronizes the time with ntp server and then stops
normally? I think I run out of ideas abouthis silly problem :P

As mentioned by you in your original post - running startsrc -s xntpd
from the command line starts the daemon and keeps it running. Then it
should also be running without any issue when it is run through
inittab. This is just to automate the start of process and to keep it
running at that runlevel.

Well, it should but this isn't happening. As I posted above, puting an
entry in inittab:
xntp:2nce:/usr/bin/startsrc -s xntpd > /dev/console 2>&1
and rebooting does NOT start xntpd. It is still inoperative and I
could't find any error in any place in AIX.
I know, it's strange. I have the latest version of AIX with latest
technical level and fix packs. Maybe there is just an unknown error.
But thank You for Your reply, appreciate this

1) Disable xntpd in the /etc/rc.tcpcip
2) Start xntpd from the inittab as the LAST entry and directly with
the debug option
...
xntp:2nce:/usr/sbin/xntpd -D 10 > /dev/console 2>&1

In case it is working move the initab entry directly AFTER the
rctcpip:23456789: .....
entry

Also check that the inittab order is correct. meaning that the network
is already configured and the rctcpip is right after srcmstr.
Example:
...
srcmstr:23456789:respawn:/usr/sbin/srcmstr # System Resource
Controller
rctcpip:23456789:wait:/e
...

Also check your /etc/rc.net file. Cuurently i assume that at the time
you try to start the xntpd the network is not configured.
For debuuging you can also write a wrapper script for the xntpd to
check the environment at the time the xntpd started.
Meaning move /usr/sbin/xntpd to /usr/sbin/xntpd.exe and create a shell
script /usr/sbin/xntpd , make it executable and reactivate the start
from the rc.tcpip.
The script itself could look like

#!/usr/bin/ksh
ifconfig -a
echo $PATH
/usr/sbin/xntpd -D

This must be of cource
/usr/sbin/xntpd.exe -D
