# Log Server Status

# This script is designed to be run at a frequent interval by something
# like cron.  It connects to the server and downloads the status
# information.  It reformats the information to a single line and logs
# it to a file.  Make sure the directory $wherelog is writable by the
# user who runs this script.

$port = "80";                   # Port on server
