The hostname command will not work on schools there are with remote help
activated. The school information is retrieved from prd.zone but using
the IP address instead of school id.

The ME variable was not being used on this script. It comes from the
current prd_schoolinfo script that retrieves the hostname with the
'hostname' command.
