I am running the following script from cron to verify my PPP connection
and if necessary, reestablish it. The script works fine except when ppp
is invoked from the script, it is a CPU hog! Any suggestions on fixing
this?
#!/bin/sh
PATH=/sbin:/usr/sbin:/bin:/usr/bin
ipaddr="199.3.232.12" # which ip address to check for basic connectivity
ppptag="simplesite" # 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 &
fi
else
ppp $ppptag &
fi
Partial output of 'top'
