Wall execution problems from cron

So I've been tasked with creating a shell script to run in a cron every few minutes to check duplex settings on my eth0 nic card. I would like for the server to send a wall message to whoever is on the console or in a terminal session. Below is what I have so far.

Code:

0,10,20,30,40,50 * * * *  /home/acc4000d/test10

I have it in my root's cron so that wall will run. Can someone tell me what I'm missing for the wall to actually happen?

Script looks like this;

Code:

#!/bin/bash
DUPLEX=$(ethtool eth0 | sed -n 's/Duplex:\(.*\)/\1/p')
if [ $DUPLEX = Half ]
then /usr/bin/wall duplex_error 
fi

annnnd the wall message file is called "duplex_error"

yum-cron

yum-cron(8)															       yum-cron(8)

NAME

       yum-cron - an interface to convieniently call yum from cron

SYNOPSIS

       yum-cron [config-file]

DESCRIPTION

       yum-cron  is  an  alternate  interface to yum that is optimised to be convenient to call from cron.  It provides methods to keep repository
       metadata up to date, and to check for, download, and apply updates.  Rather than accepting many different command line arguments, the  dif-
       ferent functions of yum-cron can be accessed through config files.

       config-file  is	used  to optionally specify the path to the configuration file to use.	If it is not given, the default configuration file
       will be used.  It is useful to be able to specify different configuration files for different use cases.  For  example,	one  configuration
       file  might  be set to update the repository metadata, and a line could be added to the crontab to run yum-cron frequently using this file.
       Then, another configuration file might be set to install updates, and yum-cron could be run from cron using this file just once each day.

FILES

       /etc/yum/yum-cron.conf
       /etc/yum/yum-cron-hourly.conf

SEE ALSO

BUGS

       There of course aren't any bugs, but if you find any, you should email
	the mailing list, yum@lists.baseurl.org, or consult bugzilla.
