+#!/bin/sh
+# This script is designed to be used by Nagios. It checks for the availability of both Microsoft SQL Server 7 and 2000.
+#
+# Requirements:
+#
+# Sqsh (http://www.sqsh.org/)
+# FreeTDS (http://www.freetds.org/)
+#
+# It was written by Tom De Blende (tom.deblende@village.uunet.be) in 2003. 
+#
+# Version 1.0.
+# Version 1.1: rewritten the initial script so that it not only works from the CLI but also from within Nagios. Always helpful...
+#
+# You might want to change these values:
