NimbostratusMonitor HTTP Site needing NTLM to Test for Return String
I need to come up with a monitor for an HTTP site that requires NTLM authentication to access. Basically, our developers have a specific ASPX file I want to call and test a for a return string. The ASPX file does a database call and verifies some backend stuff for the site and returns a "1-UP" if its cool. This is what I need to verify I receive. If not, mark the node down. For instance, http://something.someone.org/something.aspx
Now I have looked at some code examples and other threads and it seems most call for using an external monitor using cURL. For instance, http://devcentral.f5.com/wiki/default.aspx/AdvDesignConfig/HTTPMonitor_cURL_GETWithHostSpecificHeaders.html
I have tried to get this to work but I think I am missing something and just not understanding the code at all. I set the variables for URI == /whatsup.aspx and RECV == 1-UP as the author states. I took out the "-k" too as its not HTTPS.
Can anyone provide a code example that would achieve what I am trying to do?
This is what I did:

@() $Id: http_monitor_cURL+GET+HostSpecificHeaders,v 1.0 2007/06/28 15:03:15 deb Exp $
(based on sample_monitor,v 1.3 2005/02/04 18:47:17 saxon)
these arguments supplied automatically for all external monitors:
$1 = IP (nnn.nnn.nnn.nnn notation)
$2 = port (decimal, host byte order)
additional command line arguments ($3 and higher) may be specified in the monitor template
This example does not expect any additional command line arguments
Name/Value pairs may also be specified in the monitor template
This example expects the following Name/Vaule pairs:
URI = the URI to request from the server
RECV = the expected response (not case sensitive)
PIDFILE="/var/run/`basename ${0}`.${NODE}_${PORT}.pid"
kill of the last instance of this monitor if hung and log current pid
if [ -f $PIDFILE ]
then
kill -9 `cat $PIDFILE` > /dev/null 2>&1
fi
echo "$$" > $PIDFILE
remove IPv6/IPv4 compatibility prefix (LTM passes addresses in IPv6 format)
NODE=`echo ${1} | sed 's/::ffff://'`
PORT=${2}
set the value for the Host header based on IP
(defaults to IP address if IP doesn't match)
case "$IP" in
"10.10.185.39")
HOST="intranet.acc.org"
;;
"10.10.185.40")
HOST="intranet.acc.org"
;;
*)
HOST="$IP"
;;
esac
send request & check for expected response
curl --ntlm -v -u 'DOMAIN\username:pswd' http://${NODE}:${PORT}${URI} -H "Host: ${HOST}" | grep -i "${RECV}" 2>&1 > /dev/null
mark node UP if expected response was received
if [ $? -eq 0 ]
then
echo "UP"
fi
rm -f $PIDFILE
exit
Thank you.
