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
