SNI External Monitor for ADFS

It seems the while loop inside getscript() was looping indefinitely, which only appears to happen as part of the monitor. Here's a minor tweak:

!/bin/bash

pidfile="/var/run/$MONITOR_NAME.$1..$2.pid"

if [ -f $pidfile ]
    then
    kill -9 -`cat $pidfile` > /dev/null 2>&1
fi

echo "$$" > $pidfile

node_ip=`echo $1 |sed 's/::ffff://'`
node_port=$2

getscript () {
    echo 'GET / HTTP/1.1'
    echo 'Host: adfs.open-techs.com'
    echo ''
    sleep 1
    echo 'quit\n'
}

docurl () {
    IFS=$'\n'
    arr=($(getscript | openssl s_client -connect ${node_ip}:${node_port} -cipher 'ECDHE-RSA-AES256-SHA' -servername 'adfs.open-techs.com' 2>/dev/nul |grep -E '200 OK'))
    unset IFS
}

docurl

echo ${arr[0]}

if [ -n "${arr[0]}" ]
then
     Remove the pidfile before the script echoes anything to stdout and is killed by bigd
    rm -f $pidfile
    echo "up"
fi

 Remove the pidfile before the script ends
rm -f $pidfile

You may have to adjust the sleep statement depending on the application server's response.
