hey,

    i use a script which pings the far side of the connection (or something
which is always reachable if the connection is up).  if the connection is down,
it restarts ppp automatically.  i run it from cron every five minutes.  here
it is...


#!/bin/sh
PATH=/sbin:/usr/sbin:/bin:/usr/bin
ipaddr="$1" # which ip address to check for basic connectivity
ppptag="$2" # which tag in ppp.conf to use to redial
pppline=`ps -axu | grep "[p][p][p][) ]"`
if [ ! -z "$pppline" ] ; then
  if ping -c 10 $ipaddr 2> /dev/null | grep -q "100% packet loss" ; then
    ppppid=`echo $pppline | awk '{print $2}'`
    kill $ppppid
    sleep 3
    ppp $ppptag > /dev/null 2>&1 &
  fi
else
  ppp $ppptag > /dev/null 2>&1 &
fi
