Script help abt firewall alert

[telenor]

I made a following script that check every 5 minutes to check firewall is up or not, if firewall down that raise an alert only 1 time, but following script generate an alert every 5 minutes according to cronjob:



****************************************************
FILE="/var/log/fwstatus"
CHK="/tmp/fwstatus"

service iptables status | if grep ESTABLISHED 1> /dev/null 2> /dev/null

then
rm -f $CHK
echo "Firewall Running on Server"

if test -f $CHK
then
echo "Not Sending an Email"
exit
fi


else

echo `date` | tee $FILE
echo | tee -a $FILE

echo "Firewall not Running" | tee -a $FILE
echo | tee -a $FILE
echo "Starting a Firewall Service" | tee -a $FILE
echo | tee -a $FILE

/scripts/fw-scripts/fw | tee -a $FILE (This is IPTABLES Script)

if test $? = 0
then
echo "FW Run" | tee -a $FILE
else
echo "FW Stop" | tee -a $FILE
fi

echo "Now sending mail"
$MAILPROG -s "$SUBJECT" "$EMAIL" < $FILE

echo "Creating Tmp File"
touch $CHK

fi
