Mandriva 2006, patched to current spec. NTPD is installed as a service and
instructed to start on boot. Both on startup and on manual attempts to
start it from a root console, it leaves this entry in /var/log/messages

Feb 24 13:44:56 manduck ntpd[15157]: ntpd 4.2.0@1.1161-r Wed Sep 7 20:06:56 CEST 2005 (1)
Feb 24 13:44:56 manduck ntpd[15157]: precision = 1.000 usec
Feb 24 13:44:56 manduck ntpd[15157]: kernel time sync status 0040

and shuts down without any other mention anywhere that I've been able to
find.

ntpdate 0.pool.ntp.org works. 0.pool.ntp.org is in the /etc/ntp.conf file.

I have tried disabling software firewalls and configuring my ADSL
modem/router with a specific pass-through on port 123. Neither of these
have worked. I hve tried starting ntpd with various of the options. Most
of these segfault. I was once able to get the program to start but have
not been able to replicate that.

Any assistance you can offer would be appreciated. Thanks.

Can you post your /etc/ntp.conf file (without the comments)? I usually
find NTP "finicky" whever I'm trying to get it installed (again; really
makes me hate upgrades).

First, however, google for the "kernel time sync status 0040" -- that
looks kind of wierd to me (I've never noticed it in my syslog)

Various pages state that this is one of the standard lines the daemon gives on startup.

Sorry bout the flaky line endings. Here it is again, cleaned up:

server 127.127.1.0 # local clock

server 3.pool.ntp.org mask 255.255.255.255 nomodify notrap noquery

I would try making /etc/ntp.conf simple and work back up from there.
I would also use time.windows.com just to get started and
the system clock needs to be fairly close to the correct time.

Using the Mandriva Linux Control Center you would get something like

$ grep -v \# /etc/ntp.conf
fudge 127.127.1.0 stratum 10

server time.windows.com

driftfile /etc/ntp/drift
broadcastdelay 0.008


$ cat /etc/ntp/drift
77.657


$ cat /etc/ntp/step-tickers
time.windows.com

Done and did. No joy.

I don't see anything particularly odd - though the choice of local clock
servers seem unique.

I'd turn on logging and remove the "restrict kod ..." line first, and see
if it comes up ok, and slowly turn things back on. Primarily I'm looking
at the nopeer and noquery restrictions, and wondering if that's not
somehow (magically) getting applied to the external peers.

Start pulling most everything out - particularly the "broadcastdelay" (why
so high?). And check shorewall again, to make sure you're not blocking
it there (3 hours into my last debugging session ....)

bit twister

Hmmm, I have no idea where to look now.
I do have ipv6 disabled on my
Mandriva Linux release 2006.0 (Official) for i586


I am running shorewall as my firewall, all inbound ports are blocked, no
outbound port blocks. Snippet from /var/log/messages where you can see
it took several minutes to sync to time server.

Here is my latest ntp.conf file, which is stripped to the bare bones ...
and doesn't work:

fudge 127.127.1.0 stratum 10
server 127.127.1.1
server pool.ntp.org
server time.windows.com

driftfile /etc/ntp/drift
broadcastdelay 0.002
logfile /etc/ntp/ntpd.log

----------

I note that, when started as a service, the daemon is NOT making entries
into the log file or the drift file. I've thought that my copy of the
program itself may be garbled and I have replaced it twice, once with
urpmi and once by compiling from source. Arg.

remove the pool.ntp.org and the /etc/ntp/step-tickers
has to have
time.windows.com <=== followed by a carriage return
