Two new Pandora user modules
You can find them at http://pandora.sourceforge.net/en/index.php?sec=../examples/user_modules
# Check for WEB Page content change
# This user module checks contents of a web page and makes a MD5 of all
static data
# its compared with a proposed value (to get this value simply exec the
MYMD5 command). If changes, module fails.MYMD5=`echo -e “GET / HTTP/1.0nnn” | nc -w 30 pandora.sourceforge.net 80 |
grep -v “Date:” | md5sum | awk ‘{ print $1 }’`
VALIDMD5=e85c0b9018a22c1086c8e0179cd224b1
if [ “$MYMD5” != “$VALIDMD5” ]
then
MD5SUM=0
else
MD5SUM=1
fi
echo “” ”
echo “pandora.sourceforge.net_WEBContenct ”
echo “generic_proc ”
echo “$MD5SUM”
echo “# MODULE END ========================
# Check for DNS Entry change
# This user module try to compare public IP with your local IP.
# Makes a traceroute, and if needs to get out of your LAN it’s because
your public IP is not the same that
# are published in internet’s DNS. You need to adjust MAXHOPS. In a LAN
without firewalls (only your dsl router), 1 hop is needed.HOSTNAME=pandora.sourceforge.net
MAXHOPS=1
MAXHOPS2=`expr $MAXHOPS + 1`
SALIDA=`traceroute -n $HOSTNAME -w 5 -m $MAXHOPS2 2> /dev/null |

# if SALIDA != MAXHOPS, error (more than MAXHOPS hop, if this is our
local IP, no more than MAXHOPS hop its needed
if [ “$SALIDA” == “$MAXHOPS” ]
