Beyond just good programming practice, always use full paths to external
programs within your scripts. $PATH may not be what you expect it to be,
especially when being run by the nagios daemon which has a more restrictive
environment.
# (paths may be different on your system)
used=`/usr/bin/sudo /usr/bin/rsh $1 /bin/df -v | /bin/grep starlite |
/usr/bin/head -1 | /usr/bin/awk '{print $4}'`
(chop...)

You already have this value as $free; why not just use it instead of rsh'ing
again?

Bad test. Never test the functionality of a plugin as root. root can rsh into
the box but can the nagios user? Depending on how your command{} definition is
set up, you probably want to make sure that the value 'LEGACYBOX' is exactly
the same as what you have defined as the 'address' in the host{} definition.

nsca has nothing to do with it since you aren't using it. Verify that the
nagios user can rsh into the box and test your plugin as the nagios user, not
root.
