I'd like to set up a rule that would restart NTP when two conditions
hold:
a) The host is connected to my ISP (no point to bothering if I can't
get out to an external time source), and
b) The set of NTP servers the host is _trying_ to sync against _does
not_ include some of the external ones.
I could evaluate the first via something like:
PPPCOUNT=`route -n | grep ppp | wc -l`
The latter something like:
NTPSERVERS=`echo dmpeers | ntpdc | wc -l`
... And I'd want to do something like:
shellcommands:
ntpserver::
"if $PPPCOUNT > 0 and $NTPSERVERS < 5; then
/etc/init.d/ntp restart
fi"
I could write an external script that evaluates this; that may well be
the answer I go with. Is there some way I'd best evaluate this inside
cfengine?
