[pptp-server] periodically check a pptp client connections

[Vladimir Strezhnev]

I found this script a while ago in this list archives.
Sorry, can not supply the original author credentials.
Hope his posting is still in the archives and can be traced.

#!/bin/bash 
ans1=`ps -ef | grep pptp | grep -v grep | grep -v query | wc -l | /bin/awk 
'{print $1}'` 
tim=`date | awk '{print $4}'` 
dat=`date | awk '{print $1 " " $2 " " $3 }'` 
if [ "$ans1" = "0" ] 
then echo "pptp is down!" 
echo "cleaning up pptp" 
ifconfig ppp0 down 
if [ -e /var/run/ppp0.pid ]
    then kill HUP `cat /var/run/ppp0.pid` 
    fi
    if [ -e /var/run/pptp/* ]
    then rm /var/run/pptp/* 
    fi
echo "re-initiating link on $dat at $tim" 
/usr/sbin/pptp-command start 
fi

Sometimes the script failed to make a total cleen-up, so we used slightly 
modified one for about a year without problems. It was run by cron every min.

#!/bin/bash 
ans1=`route -n | grep ppp0 | grep -v grep | grep -v query | wc -l | /bin/awk 
'{print $1}'` 
tim=`date | awk '{print $4}'` 
dat=`date | awk '{print $1 " " $2 " " $3 }'` 
if [ "$ans1" != "3" ] 
then echo "pptp is down!" 
echo "cleaning up pptp" 
ifconfig ppp0 down 
if [ -e /var/run/ppp0.pid ]
    then kill HUP `cat /var/run/ppp0.pid` 
    fi
    if [ -e /var/run/pptp/* ]
    then rm /var/run/pptp/* 
    fi
echo "re-initiating link on $dat at $tim"
/usr/sbin/pptp-command stop  
sleep 5
/usr/sbin/pptp-command start 
fi
