Thanks, I see how I could use this. I'm still a litte unclear on the
meaning of the "state" word. For example, the ntp-wait perl script
expects this:
if (/^state=4/) {
print "\bOK!\n" if ($opt_v);
exit 0;
}
But my ntp-4.2.0 doesn't return "state=4" even though it appears to be
sync'd:

I read the ntpq.htm page but there wasn't any description of the
semantics. Any pointers?
Thanks
