xntpd config help on 2 SCO 5.05 boxes

[lec maj]

I have 2 Sco 5.05 boxes and wanted to syncronize them in time. They are
on a local lan and there is no connection to outside world. There is one
trick though. If either machine ever dies it has to come up and get the
time from the other one that was already up. So that means that somehow
both have to be master and slave at the same time.

I am mainly concerned on how i should set up the /etc/ntp.conf

Thank you

I think I would consider using ntpdate running in cron on both machines
pointed at the other system. On my network, I use it once each day but
you can set them to run more often if better synchronization is needed.
Then in each start up you could add a line to sync to the other. I
would probably add a file named S99sync in the /etc/rc2.d directory with
the ntpdate command.

Note that ntpdate won't work if xntpd is running, check man for both.

Hope that is some help.

I think the perfect choice in your situation is just not using xntpd but
timed with option -M. Without any tricks.

Am I wrong?

I think i have it working well with xntpd, syncronizying very nicely every
night.

One thing that i was puzled about, if i do right after bootup of both machines

ntpq -p

i get the master information, and the ip 127.127.1.1, but i do not get the "
* " in front of it. Now, after reading the man pages on xntpd multiple times
it seems that xntpd will not work properly and will not accept ntpdate if the
" * " is not there. Within 20 mins the " * " comes up and all works well.

Is there a timeout somewhere that i need to set to 0, not to sure what time
out thought, -t maybe? Right now my command for start up of xntpd looks like
this:

/etc/xntpd -c /etc/ntp.conf

ntp.conf has a server 127.127.1.1 and broadcast to local subnet that both
machines are on.

Sorry for jumping in, but I got myself really confused when I
was first learing ntpdate and xntpd. I was trying to
mess with the xntpd while it was running, but I was always
using the wrong app! Use xntpdc, not ntpq :)
I don't think they're interchangeable.

Cheers,
