Hi,
An elegant (I think) way of solving this is to
put scripts in /etc/ppp/ip-[up|down].d/ to stop
and start ntpd when pppd reconnects.
My /etc/ppp/ip-down.d/ntp-server simply says,
-----
#!/bin/sh
[ -x /usr/sbin/ntpd ] || exit 0
echo "Stopping NTP server"
/etc/init.d/ntp-server stop
-----
and my /etc/ppp/ip-up.d/ntp-server,
-----
#!/bin/sh
[ -x /usr/sbin/ntpd ] || exit 0
echo "Starting NTP server"
/etc/init.d/ntp-server start
-----
Just make sure these scrips are executable (755).
