this works even better here is linkwatch.sh
run it as root linkwatch & it checks even min and only restarts as long as
it HAS to! even catchs half dead links :))

#!/bin/sh
#
ADMIN=child
WATCH=your.isps.gateway.ip
RESTART='killall ppp ; /usr/sbin/ppp -auto city > /dev/null &'

while [ true ]; do
for minute in 1 2 3; do
  sleep 60
  if [ X"`/sbin/ping -nc3 ${WATCH} | /usr/bin/grep '100%'`" != X ]; then
       ${RESTART}
       echo mpd restarted | /usr/bin/Mail -s "auto restart ppp" ${ADMIN}
    else
 fi
