# description: Starts the NDT Web server
# written by Peter Bertoncini <pjb@anl.gov>
#
# Customized NTP startup script for Internet Network Performance Tools
# Live CD.  The process for this tool, and all the others, it to let 
# Knoppix take care of some customization during the boot phase.  Knoppix
# will automatically look for, and execute, a knoppix.sh script on an
# attached drive.  This means that we will store the customized file
# on a USB thumb drive.  At boot time the boot process will find and
# execute a knoppix.sh script that will copy the config files into
# the proper place.  If they don't exist, then prompt the user to
# customize things.
#
# At shutdown, copy the files back to the mounted USB drive.
# Rich Carlson - 4/20/06
# 
# Added a function to alert a daemon that NDT has started up, along with the
# location of the configuration file
# Aaron Brown - 2008-07-02
